<div>The '''testnet''' is an alternative Bitcoin [[block chain]], to be used for testing. Testnet coins are separate and distinct from actual bitcoins, and are never supposed to have any value. This allows application developers or bitcoin testers to experiment, without having to use real bitcoins or worrying about breaking the main bitcoin chain.<br />
<br />
Run bitcoin or bitcoind with the -testnet flag to use the testnet (or put testnet=1 in the bitcoin.conf file).<br />
<br />
There have been three generations of testnet. Testnet2 was just the first testnet reset with a different genesis block, because people were starting to trade testnet coins for real money. '''Testnet3''' is the current test network. It was introduced with the 0.7 release, introduced a third genesis block, a new rule to avoid the "difficulty was too high, is now too low, and transactions take too long to verify" problem, and contains blocks with edge-case transactions designed to test implementation compatibility. On the December 21 of 2015 SegNet was deployed, to test the Wuille's Segregated Witness proposal.<br />
<br />
==Differences==<br />
* Default Bitcoin network protocol listen port is 18333 (instead of 8333)<br />
* Default RPC connection port is 18332 (instead of 8332)<br />
* Bootstrapping uses different DNS seeds.<br />
* A different value of ADDRESSVERSION field ensures no testnet Bitcoin addresses will work on the production network. (0x6F rather than 0x00)<br />
* The protocol message header bytes are 0x0B110907 (instead of 0xF9BEB4D9) <br />
* Minimum [[difficulty]] of 1.0 on testnet is equal to difficulty of 0.5 on mainnet. This means that the mainnet-equivalent of any testnet difficulty is half the testnet difficulty. In addition, if no block has been found in 20 minutes, the difficulty automatically resets back to the minimum for a single block, after which it returns to its previous value.<br />
* A new genesis block<br />
* The IsStandard() check is disabled so that non-standard transactions can be experimented with.<br />
<br />
==Genesis Block==<br />
<br />
Testnet uses a different genesis block to the main network. You can find it [https://www.biteasy.com/testnet/blocks/000000000933ea01ad0ee984209779baaec3ced90fa3f408719526f8d77f4943 here] or [http://blockexplorer.com/testnet/b/0 here].<br />
The testnet was [https://github.com/gavinandresen/bitcoin-git/commit/feeb761ba07af74a7cd78b8c8f7c2a961fd9ea1c reset with a new genesis block] for the 0.7 bitcoin release.<br />
<br />
==Size==<br />
Testnet receives less transactions than the main block chain and is typically much smaller in size. As of June 2016 the size of the data on disk was 7GB, containing data for about 4 years worth of testnet activity. Downloading this data required about 6GB of network activity peaking at 2MB/s rate of transfer.<br />
<br />
==Mining==<br />
[[solo.ckpool]] has a testnet bitcoin solo mining implementation available, without the need to set up bitcoind locally.<br />

<hr />
<div>[[File:FirstBitcoinBills.jpg|thumb|right|200px|Casascius holding early paper wallets]]<br />
<br />
In the most specific sense, a '''paper wallet''' is a document containing all of the data necessary to generate any number of Bitcoin [[private key]]s, forming a wallet of keys. However, people often use the term to mean ''any'' way of storing bitcoins offline as a physical document. This second definition also includes '''paper keys''' and '''redeemable codes'''. A paper key is a single key written on paper that is used multiple times like a wallet (this is strongly [[address reuse|discouraged]]). A redeemable code is a single key intended to be funded and "redeemed" only once: these are commonly used for gifts and as part of physical Bitcoin coins/notes.<br />
<br />
Storing bitcoins on paper wallets is not safe unless very strict security precautions are undertaken during their initial preparation. (See below.)<br />
<br />
__TOC__<br />
<br />
==Use cases==<br />
<br />
===Tips and gifts===<br />
<br />
By creating a keypair, one can store bitcoins on a physical medium to be left as a tip or a gift.<br />
The recipient then sweeps the private key to their own wallet.<br />
<br />
===Physical tokens===<br />
<br />
A trusted provider can hide the private key inside a tamper-resistant token, and issue them as a form of bitcoins.<br />
This requires those who accept it as payment to trust that when the provider produced the tokens, they loaded them with the correct amount of bitcoins, and that they have not been tampered with since then.<br />
To redeem the bitcoin value, the token must be destroyed to access the private key.<br />
Often a bitcoin address is embedded on the outside visible, but there is no guarantee (without destroying the token) that this matches the private key inside, or, even if it does, that the private key is not replicated on multiple tokens or saved by the producer.<br />
<br />
===Wallets===<br />
<br />
Proper paper wallets are often a very secure way of storing bitcoins, since they are not typically exposed to malware. They can also be easily stored securely in safes and safe deposit boxes. However, it may be more difficult to securely "backup" paper wallets, and due to the current sub-optimal software support, it may be easier to make a mistake that causes loss of bitcoins.<br />
<br />
Sometimes people try to use single keys as true bitcoin wallets. However [[address reuse]] is very bad for privacy and security. Because of this, one is forced to choose between hazardous options:<br />
* '''Use the key only once to receive, and only once to send the full amount.''' This requires the user to know the full amount he wants to store in advance, and often leads to the next situation:<br />
* '''Create multiple keys.''' By using more than one key, the user can receive more than once using a different address each time, including using new addresses for change. This is very complicated, and makes it easy to accidentally reuse addresses, produce the wrong change/fee combination, lose some keys, spend hours searching for the right key, etc. Not even skilled bitcoin experts are comfortable managing their own keys manually like this.<br />
<br />
Therefore, it is highly recommended that you use proper paper wallets which allow you to generate an infinite number of addresses from a single seed.<br />
<br />
==Encoding/formatting==<br />
<br />
[[File:BitcoinPaperWallet-sample.jpg|thumb|right|300px|Paper keypair with private key secured beneath folds]]<br />
[[File:PaperWallets-offlineaddress-com.png|200px|thumb|right|Paper keypair]]<br />
Proper, multi-key paper wallets usually take the form of a multi-word [[Deterministic wallet | HD wallet]] seed mnemonic. The list of several words corresponds to some binary data that is used to generate all of the addresses. Words are used to make it easier to avoid and correct errors. Trying to memorize an entire seed mnemonic is very difficult and is generally not recommended.<br />
<br />
A single key (for use in insecure single-key paper wallets or redeemable codes) can be represented in several formats, but typically the Wallet Import Format (WIF) is used, since keys represented that way are very short (51 characters) and thus easy to re-enter when importing or "sweeping" it for withdrawal.<br />
<br />
==Creation of a paper wallet==<br />
<br />
===Generation of secure keys===<br />
<br />
The private seed is used to prove your right to spend the bitcoins transferred to the paper wallet, and as such should be kept hidden and secret.<br />
If the private seed on a paper wallet is exposed (for example in a photograph) then the wallet may be used by anyone who sees it.<br />
To guard against accidental revelation, the private key displayed on the paper wallet may be encrypted or split into several different parts (for example using [https://en.wikipedia.org/wiki/Shamir%27s_Secret_Sharing Shamir's secret sharing scheme]).<br />
At the very least, the private key should be well hidden e.g. by folding the wallet in half and sealing it shut.<br />
<br />
Currently, at least [[Armory]] and [[Electrum]] support generating mnemonic codes for their wallets, which can be written down or printed to make a multi-key paper wallet.<br />
<br />
Several tools exist for producing single keys, including [[Bitcoin Address Utility]], [[vanitygen]], and [[Cwallet]]. Again, using single keys for anything except one-time ''transfers'' of bitcoins is strongly [[address reuse|discouraged]].<br />
<br />
===Web-based key generators===<br />
<br />
Some websites feature free open-source client-side keypair/wallet generators written in JavaScript.<br />
Keypairs/wallets generated by JavaScript or using websites are inherently weak and insecure, and unless the code of the website is audited every time it is used, it may leak the generated keys back to the server—especially if un-audited Javascript is downloaded and run locally.<br />
Even with careful code auditing, browser plugins or other websites may compromise the environment.<br />
<br />
Some established web-based wallets that can be downloaded and ran "offline:<br />
* BitcoinPaperWallet.com<br />
* BitAddress.org<br />
<br />
===Recommendations===<br />
* Disconnecting from the Internet guarantees that that the paper wallet generator is truly self-contained and isn't transmitting your keys online. <br />
* Verifying the integrity of the code (and the trustworthiness of the author) is important to make sure a hacker hasn't modified the download so that it generates predictable seeds instead of truly random ones.<br />
* Remember, spyware and viruses often attempt to monitor your computer activities so that their authors can steal from you. They are interested in passwords to online accounts, and anything of value. Bitcoin wallets are something of value that have already been targeted by malware. If your computer is infected with spyware or viruses - even if there are no symptoms, or your antivirus isn't reporting anything - then anything you type, view, or save on your computer, could potentially be stolen by someone remotely controlling your computer. Your private seed can then be intercepted while you enter it, so only enter a Bitcoin private seed into your computer when you are certain it is secure (such as a fresh boot of a LiveCD).<br />
* The wallet should never be saved to a computer hard drive or sent via email or other network connections. You should also never scan/type your key into your computer, except at the moment you are using it.<br />
* If possible, the wallet should be kept hidden, for example by using BIP38 encryption (single keys only), and/or by folding the paper to hide the private key so that a photograph or photocopy of it will not reveal or replicate the private key.<br />
* A web-based generator should not be used.<br />
* A generator should use an appropriate source of random numbers (entropy). This means that the generated keys aren't predictable. If the addresses come from a predictable or partially-predictable patterns like pseudorandom numbers <ref>[https://en.wikipedia.org/wiki/Pseudorandomness#Cryptography Pseudorandomness] '' is not enough for strong cryptography''</ref>, someone else who can predict the pattern can steal the balance. Randomness should NEVER be human generated, as the human brain is incapable of secure entropy.<br />
* Remember that unlike wallets (paper or otherwise), a single paper key is only good to receive a single payment, and must be redeemed in its entirety.<br />
<br />
===Printer Security===<br />
<br />

==Redeeming Keys and Withdrawing Funds==<br />
<br />
This section applies only to single-key paper "wallets".<br />
<br />
Paper keys, when used as wallets, are very different from wallets such as Bitcoin Core in that it is not possible to transfer (withdraw) a ''portion'' of a key's bitcoins.<br />
The only way to withdraw funds is to import or "sweep" the ''entire'' received amount to a new address, typically a wallet or online exchange.<br />
Once the transfer has been confirmed, ''the key should not be reused''.<ref>[http://www.reddit.com/r/Bitcoin/comments/1c9xr7/psa_using_paper_wallets_understanding_change/ reddit.com] ''Using Paper Wallets and Understanding Change''</ref><br />
<br />
There are various methods for copying the private key data to other wallets.<br />
* bitcoind supports an "importprivkey" RPC method for this purpose.<br />
* Bitcoin-Qt's debug console can also be used in a similar way (see also [[How to import private keys in Bitcoin Core 0.7+]]).<br />
* [[BlockChain.info]] and [[Armory]] can also import them directly into wallets.<br />
* [http://MyCelium.com/download Mycelium] is a Android mobile wallet with an easy to use "cold storage" spending function. It is also available via Android and iTunes playstore. The iTunes version may not yet support cold storage spending.<br />
<br />
Note that importing a private key that may be compromised can result in the entire wallet becoming insecure.<br />
For this reason, sweeping is generally recommended over importing.<br />

<br />
In the most specific sense, a '''paper wallet''' is a document containing all of the data necessary to generate any number of Bitcoin [[private key]]s, forming a wallet of keys. However, people often use the term to mean ''any'' way of storing bitcoins offline as a physical document. This second definition also includes '''paper keys''' and '''redeemable codes'''. A paper key is a single key written on paper that is used multiple times like a wallet (this is strongly [[address reuse|discouraged]]). A redeemable code is a single key intended to be funded and "redeemed" only once: these are commonly used for gifts and as part of physical Bitcoin coins/notes.<br />
<br />
Storing bitcoins on paper wallets is not safe unless very strict security precautions are undertaken during their initial preparation. (See below.)<br />
<br />
__TOC__<br />
<br />
==Use cases==<br />
<br />
===Tips and gifts===<br />
<br />
By creating a keypair, one can store bitcoins on a physical medium to be left as a tip or a gift.<br />
The recipient then sweeps the private key to their own wallet.<br />
<br />
===Physical tokens===<br />
<br />
A trusted provider can hide the private key inside a tamper-resistant token, and issue them as a form of bitcoins.<br />
This requires those who accept it as payment to trust that when the provider produced the tokens, they loaded them with the correct amount of bitcoins, and that they have not been tampered with since then.<br />
To redeem the bitcoin value, the token must be destroyed to access the private key.<br />
Often a bitcoin address is embedded on the outside visible, but there is no guarantee (without destroying the token) that this matches the private key inside, or, even if it does, that the private key is not replicated on multiple tokens or saved by the producer.<br />
<br />
===Wallets===<br />
<br />
Proper paper wallets are often a very secure way of storing bitcoins, since they are not typically exposed to malware. They can also be easily stored securely in safes and safe deposit boxes. However, it may be more difficult to securely "backup" paper wallets, and due to the current sub-optimal software support, it may be easier to make a mistake that causes loss of bitcoins.<br />
<br />
Sometimes people try to use single keys as true bitcoin wallets. However [[address reuse]] is very bad for privacy and security. Because of this, one is forced to choose between hazardous options:<br />
* '''Use the key only once to receive, and only once to send the full amount.''' This requires the user to know the full amount he wants to store in advance, and often leads to the next situation:<br />
* '''Create multiple keys.''' By using more than one key, the user can receive more than once using a different address each time, including using new addresses for change. This is very complicated, and makes it easy to accidentally reuse addresses, produce the wrong change/fee combination, lose some keys, spend hours searching for the right key, etc. Not even skilled bitcoin experts are comfortable managing their own keys manually like this.<br />
<br />
Therefore, it is highly recommended that you use proper paper wallets which allow you to generate an infinite number of addresses from a single seed.<br />
<br />
==Encoding/formatting==<br />
<br />
[[File:BitcoinPaperWallet-sample.jpg|thumb|right|300px|Paper keypair with private key secured beneath folds]]<br />
[[File:PaperWallets-offlineaddress-com.png|200px|thumb|right|Paper keypair]]<br />
Proper, multi-key paper wallets usually take the form of a multi-word [[Deterministic wallet | HD wallet]] seed mnemonic. The list of several words corresponds to some binary data that is used to generate all of the addresses. Words are used to make it easier to avoid and correct errors. Trying to memorize an entire seed mnemonic is very difficult and is generally not recommended.<br />
<br />
A single key (for use in insecure single-key paper wallets or redeemable codes) can be represented in several formats, but typically the Wallet Import Format (WIF) is used, since keys represented that way are very short (51 characters) and thus easy to re-enter when importing or "sweeping" it for withdrawal.<br />
<br />
==Creation of a paper wallet==<br />
<br />
===Generation of secure keys===<br />
<br />
The private seed is used to prove your right to spend the bitcoins transferred to the paper wallet, and as such should be kept hidden and secret.<br />
If the private seed on a paper wallet is exposed (for example in a photograph) then the wallet may be used by anyone who sees it.<br />
To guard against accidental revelation, the private key displayed on the paper wallet may be encrypted or split into several different parts (for example using [https://en.wikipedia.org/wiki/Shamir%27s_Secret_Sharing Shamir's secret sharing scheme]).<br />
At the very least, the private key should be well hidden e.g. by folding the wallet in half and sealing it shut.<br />
<br />
Currently, at least [[Armory]] and [[Electrum]] support generating mnemonic codes for their wallets, which can be written down or printed to make a multi-key paper wallet.<br />
<br />
Several tools exist for producing single keys, including [[Bitcoin Address Utility]], [[vanitygen]], and [[Cwallet]]. Again, using single keys for anything except one-time ''transfers'' of bitcoins is strongly [[address reuse|discouraged]].<br />
<br />
===Web-based key generators===<br />
<br />
Some websites feature free open-source client-side keypair/wallet generators written in JavaScript.<br />
Keypairs/wallets generated by JavaScript or using websites are inherently weak and insecure, and unless the code of the website is audited every time it is used, it may leak the generated keys back to the server—especially if un-audited Javascript is downloaded and run locally.<br />
Even with careful code auditing, browser plugins or other websites may compromise the environment.<br />
<br />
Some established web-based wallets that can be downloaded and ran "offline:<br />
* BitcoinPaperWallet.com<br />
* BitAddress.org<br />
<br />
===Recommendations===<br />
* Disconnecting from the Internet guarantees that that the paper wallet generator is truly self-contained and isn't transmitting your keys online. <br />
* Verifying the integrity of the code (and the trustworthiness of the author) is important to make sure a hacker hasn't modified the download so that it generates predictable seeds instead of truly random ones.<br />
* Remember, spyware and viruses often attempt to monitor your computer activities so that their authors can steal from you. They are interested in passwords to online accounts, and anything of value. Bitcoin wallets are something of value that have already been targeted by malware. If your computer is infected with spyware or viruses - even if there are no symptoms, or your antivirus isn't reporting anything - then anything you type, view, or save on your computer, could potentially be stolen by someone remotely controlling your computer. Your private seed can then be intercepted while you enter it, so only enter a Bitcoin private seed into your computer when you are certain it is secure (such as a fresh boot of a LiveCD).<br />
* The wallet should never be saved to a computer hard drive or sent via email or other network connections. You should also never scan/type your key into your computer, except at the moment you are using it.<br />
* If possible, the wallet should be kept hidden, for example by using BIP38 encryption (single keys only), and/or by folding the paper to hide the private key so that a photograph or photocopy of it will not reveal or replicate the private key.<br />
* A web-based generator should not be used.<br />
* A generator should use an appropriate source of random numbers (entropy). This means that the generated keys aren't predictable. If the addresses come from a predictable or partially-predictable patterns like pseudorandom numbers <ref>[https://en.wikipedia.org/wiki/Pseudorandomness#Cryptography Pseudorandomness] '' is not enough for strong cryptography''</ref>, someone else who can predict the pattern can steal the balance. Randomness should NEVER be human generated, as the human brain is incapable of secure entropy.<br />
* Remember that unlike wallets (paper or otherwise), a single paper key is only good to receive a single payment, and must be redeemed in its entirety.<br />
<br />
===Printer Security===<br />
<br />
Some advanced printers have internal storage (even hard drives) that preserve copies of printouts. This is a risk if someone gets access to your printer, or if you dispose of your printer. There is also the possibility that a smart enough printer can be hacked. (Consider [http://en.wikipedia.org/wiki/Stuxnet StuxNet] which was able to rewrite the firmware of non-computer devices indirectly connected to the Internet) If this concerns you, use a "dumb" printer, and never let your printer have access to the Internet or to an Internet-connected computer.<br />

<div>= Using Blockchain.info =<br />
As of August 2012, possibly the easiest way to import a private key is using [[Blockchain.info]]'s My Wallet service. When successully imported through the "Import/Export" screen, the bitcoins assigned to a private key can be immediately sent to any Bitcoin address. The [[MtGox]] Bitcoin exchange will allow individual private keys to be redeemed but since they must sweep the address, the user must wait 6 confirmations for access to the funds. There is an API method to import an entire wallet.dat as well.<br />

As of August 2013, [[File:BIPS.gif|20px|link=https://bips.me]] [[BIPS]] allows for easy import of private key using Paper Wallet - Import. User can choose to type in the private key manually or scan a QR code containing the private key using the camera. The user must wait 6 confirmations for access to the funds, and system is based on batch importation.<br />

Steps described are with the following settings:<br />

<br />
== Partial spend from cold storage ==<br />
Use this function if you would like to keep some funds on the paper wallet.<br />
# Download [https://play.google.com/store/apps/details?id=com.mycelium.wallet&hl=en Mycelium] from the Android Play Store<br />
# Press the menu button and select "Cold Storage"<br />
# Scan in private key<br />
# Select your destination address<br />
# Select the amount <br />
## Press the blue currency tag at the top to toggle currency.<br />
# Send!<br />
<br />
After spending, the private key in memory is destroyed so the paper private key remains somewhat secure.<br />
<br />
== Import key from a paper wallet ==<br />
Use this function if you would like to import a private key so all funds are immediately available for spending.<br />

After importing this paper private key, you might consider destroying the original so it cannot be found and your funds stolen. Alternatively, you can keep it safe to be used as an offline backup.<br />

<br />
If you are using [[Cold storage]], a [[Paper wallet]] or generating [https://bitcointalk.org/index.php?topic=25804.0 vanity addresses] you may have a need to import a [[Private key]]. Since Bitcoin-QT/bitcoind v0.6.0, you can import private keys using built-in RPC command [[importprivkey]]. Before v0.6.0, you needed to rely on third-party [[wallet.dat]] manipulation tool such as [[Pywallet]]. <br />
<br />
<br />
<br />
<br />
This article describes how to import a private key through the RPC API of bitcoind, which is a topic for advanced users.<br />
<br />
'''Note that importing a key to bitcoind and/or Bitcoin-Qt may be dangerous and is not recommended unless you understand the full details of how it works'''<br />
<br />
== Start Bitcoin client ==<br />
Unlike third-party wallet.dat manipulation tools such as [[Pywallet]], you do not have to close the Bitcoin client before proceeding. Instead, you need to start the bitcoind server.<br />
* Close bitcoin-qt and start ''bitcoind -damon'' in Terminal Emulator. The version of bitcoind MUST be the same as bitcoin-qt!<br />
<br />
Bitcoin-QT does not enable its RPC interface by default. To enable it:<br />
* Close Bitcoin-QT and restart it with ''bitcoin-qt -server''.<br />
<br />
== Unlock your wallet ==<br />
If you have an encrypted wallet (recommended), you need to unlock it temporarily before importing private keys. The RPC command for unlocking an encrypted wallet is ''walletpassphrase <passphrase> <timeout>''. Typing this directly in a bash terminal will leave your wallet passphrase directly in the bash history but there are a couple of techniques you can use to avoid this. Simply add a space before the command:<br />
<br />
(space)bitcoind walletpassphrase yourpassphrase 120<br />
<br />
Another alternative is to use a bash variable:<br />
<br />
read x<br />
(input your passphrase)<br />
bitcoind walletpassphrase "$x" 120 # Do not set the timeout too long or too short.<br />
<br />
== Import Private key(s) ==<br />
The last command unlocked your wallet temporarily for 120 seconds, during which time you must import your private keys. Since private keys can be as important as your passphrase, you may want to use the same techniques as above to prevent their being recorded in bash history (bash variable or space before the command):<br />
<br />
(space)bitcoind importprivkey "5yourveryveryveryverylongprivatekeystring" "my-new-key" # "my-new-key" is a label for the key/address pair and is optional<br />
<br />
The importing process is now started. Bitcoind will rescan the entire block data to ensure this key has not been used before. This process will take from one to two minutes, depending on your CPU performance. DO NOT abort it before finishing!<br />
<br />
If no errors occurs, the import is a success and Bitcoin-QT users will be able to see the new address in the GUI immediately. If you need to import more keys, just repeat the instructions above. There is currently no command to import a batch of private keys so you will need to wait a minute or two for each key to be imported.<br />
<br />
== Cleaning up ==<br />
<br />
bitcoind walletlock<br />
<br />
This will lock your wallet again (so you don't have to wait for timeout)<br />
<br />
unset x<br />
unset y<br />
<br />
These commands will clear the passphrase and private key from memory if you used the ''read'' technique. If you started bitcoind, you will need to stop it before Bitcoin-QT will start again:<br />
<br />
bitcoind stop<br />
<br />
===Deleting Keys===<br />
At some point, you may wish to delete private keys from a wallet.dat file but as of version v0.6.0 of Bitcoin-QT/bitcoind, there is no RPC method available for this purpose.<br />

<hr />
<div>Bitcoin Wednesday is a global meetup event scheduled for the first Wednesday of every month.<br />
<br />
The [https://bitcointalk.org/index.php?topic=248358.msg2635123#msg2635123 genesis] of this event was a forum post highlighting the coincidental synchronicity of nearly a dozen local bitcoin meetups.<br />
<br />
If you are a member of any of the [https://en.bitcoin.it/wiki/Meetups local bitcoin meetups], you should make every effort to promote a special meeting for Bitcoin Wednesday.<br />
<br />
Add your city here, or on [https://bitcointalk.org/index.php?topic=248358.msg2635123#msg2635123 the discussion for this event].<br />
<br />
==Start Your Own Local Community==<br />
# '''Find a good location'''. It helps if the meeting place is accessible, has WiFi, and food and beverages. The merchant does not have to accept Bitcoin yet.<br />
# '''Add your city to the list'''. Also announce your meetings in the [https://bitcointalk.org/index.php?topic=248358.msg2635123#msg2635123 forum topic].<br />
# '''Invite local Bitcoin people'''. Some great resources to find locals are [http://bitcoins.meetup.com Meetup.com], and [http://LocalBitcoins.com LocalBitcoins.com]. You may also find numerous regional groups on social media sites like [http://reddit.com/r/bitcoin Reddit], Facebook, and Google Plus.<br />
# '''Show up and have fun'''. If the meeting spot merchant will allow it, consider making a banner/display that identifies your group as Bitcoin friendly. This will advertise your presence to other patrons and generate more interest.<br />
<br />
==Event Agenda Ideas==<br />
* Socialize with other great people interested in Bitcoin: Newcomers, gurus and early pioneers, writers, entrepreneurs, economists, investors, activists, etc. Celebrities have been known to drop in on these events. Don't see someone you think should be there, just bring them along.<br />
<br />
* Learn more and teach others.<br />
<br />
* Buy, sell, barter. Keep the coins circulating in the community.<br />
<br />
* Talk about how to spread Bitcoin to more people, more businesses.<br />
<br />
* Engage in fascinating conversations.<br />
<br />
* Demonstrate or pitch your latest Bitcoin project.<br />
<br />
* Hold presentations and debates.<br />
<br />
* Indulge in good food and drink.<br />
<br />

=== Popular Mining Cards ===<br />
This information has been included to make choosing a card easier. The cards selected are generally readily available online. Once you have purchased a card or cards, use the tables below to compare different configurations and setups.<br />
=== genBTC's Card Comparison Spreadsheet ===<br />
The purpose of this chart is 1) Update used prices 2) To consolidate multiple sources of information into an at-a-glance format. 3) Provide 3 hashrate columns to make it easier to figure out performance before 4) You use this table to make informed decisions about purchasing a card for mining.<br><br />
Only edit Common MH/s. MH/s #1 and MH/s #2 were outsourced.<br><br />
I will continue to work on this chart, and it is a work in progress. <br><br />
Created February 25th 2013, Updated February 27th 2013 <br><br />

Ebay Price taken from http://cgi5.ebay.com/ws/eBayISAPI.dll?SellHub3 and questionable prices marked with a ? <br><br />
Cheapest $ = Used price. Sourced from All over the internet as if I had to buy the card today.<br><br />

<br />
=== Card Comparison Spreadsheet ===<br />
This spreadsheet performs several calculations and displays a visualization graph of a theoretical mining rig over time. It can be used to visualize any "what if" scenarios to better wrap your head around which card is the best choice under different conditions. Bright Yellow Boxes are editable, and affect the calculations. Dark Yellow Boxes are editable for notation, but don't affect the calculations. The Green highlighted card is the best under those conditions, the Blue highlight is second best, the Orange highlight is third best. Higher MHash/s performance can be obtained for each card through overclocking, but that drives up the wattage draw of the cards, and I did not have that complete dataset so I used the "average" MHash/s values listed here. <br /><br />

Might you wish to throttle CPU load a bit, so it doesn't reach 100°C, it can be done with Battle Encoder Shirase to a margin, like, -15% of available CPU cycles.<br />
<br />
Often, the best combination to be is to throttle CPU miner to -5% '''AND''' set it to least of priority levels, so as not to choke GPU miner up.<br />

[[de:Treffen]]</div>JulianToshhttps://en.bitcoin.it/w/index.php?title=How_to_accept_Bitcoin,_for_small_businesses&diff=33662How to accept Bitcoin, for small businesses2012-12-12T14:12:22Z<p>JulianTosh: </p>
<hr />
<div>This guide is intended for small business owners who wish to help promote Bitcoin by accepting it as payment for goods and services. It's written with the assumption that you operate a regular business that sells goods or services for regular national currency such as dollars, and that you wish to accept Bitcoin as another legal way to pay, and that you intend to pay taxes on your Bitcoin income just like any other income.<br />
<br />
With Bitcoin being touted as a way to conduct anonymous transactions and as way to compete with government currency, many small business owners wonder what's the right way to accept and account Bitcoin, or if it's legal or ethical, or whether and how they should pay taxes on income received through Bitcoin.<br />
<br />
As far as we know, Bitcoin isn't yet formally recognized by governments and authorities as a "currency". But in practice, Bitcoin is likely no different than accepting payment in other forms, such as cash, or gold, or scrip, or gift cards or foreign currency. We think that it is pretty much the same as the local businesses of Great Barrington, Massachusetts choosing to accept their locally-printed [http://www.reuters.com/article/2007/06/19/us-usa-economy-berkshares-idUSN0530157720070619 "Berkshire Bucks"] to support their local economy.<br />
<br />
==Starting to accept Bitcoin for transactions==<br />
Accepting Bitcoin at a small business is best started in whichever manner keeps the accounting simple for you. This will vary by the type of business you are operating.<br />
<br />
===Start with a sign===<br />
[[{{ns:file}}:WeAcceptBitcoin.png]]<br />
<br />
If you expect that the number of people interested in using Bitcoin is small, you might simply start by posting a sign or a note: "We Accept Bitcoin", and ask people to contact you directly in order to make a payment. Even if hardly anybody uses Bitcoin as a payment method, you're helping Bitcoin in two ways: one, by increasing awareness, and two, by making your customers more willing to accept Bitcoin as payment from others in the future, because now they know somewhere they can spend it.<br />
<br />
===Utilize a merchant solution===<br />
If you sell things on your website (goods or services), you'll want to use a [[#Merchant Services|Bitcoin merchant solution]] to accept the Bitcoins (you can usually opt to have them converted to USD or other currencies automatically). If you sell things in a brick and mortar shop, customers can pay using their mobile phone app (for example [http://www.paytunia.com Paytunia] or [http://www.blockchain.info/wallet Blockchain.info's app]), so it's best if you can place a QR code near your register to which the customers can scan with their phone and pay (use http://ma.eatgold.com/accept to make a QR code sign).<br />
<br />
===Accounting===<br />
When a customer makes a payment, you might simply issue a credit to their account. Ideally, you want to enter it in a way that suggests you received a payment. You could consider entering it as a "discount", but you may want to consider whether this inappropriately disguises the nature of the transaction. If on the other hand, you're giving "discounts" for Bitcoins, but then you are selling the Bitcoins for currency and then counting that as income, then chances are good that your calculation of income is making up for it. Ask your accountant.<br />
<br />
===Businesses that offer gift cards===<br />
If your business sells gift cards or gift certificates, you may find that the easiest way to accept Bitcoin is to accept it only for the purchase of gift cards, and then require the gift cards to be used for actual purchases of goods or services. This way, the accounting practices you already have in place for processing gift cards can be put to use. The accounting for Bitcoins would then be minimized to tracking sales of a single SKU.<br />
<br />
This method is also ideal for retail food establishments and convenience stores, where the payment of Bitcoins through a mobile phone for a small daily food purchase might be cumbersome or disruptive, especially in front of a line of other customers. Bitcoins in this case would be best used to reload prepaid cards that can then be swiped at point-of-sale.<br />
<br />
If you don't accept gift cards, but you already accept credit cards through a swipe terminal, consider the possibility that you could add a retail gift card system through the swipe terminal you already own. Many point-of-sale terminals, including ones from VeriFone&reg;, are designed around the ability to support multiple applications on the same terminal. Gift cards are also highly profitable because of "breakage", or in other words, the fact that a significant percentage of them never get redeemed.<br />
<br />
You could consider adding a private label gift card program from a provider who specializes in this, not just as a jumpstart to accepting Bitcoins, but as an extra boost to income. A private label gift card service provider necessarily have to handle your funds - they can simply provide a solution that keeps track of the balance on the cards on your behalf, including features that allow users to check their balances by phone or by web. Such a solution, of course, is also what makes the cards swipeable through the card reader.<br />
<br />
===Businesses that mail invoices===<br />
Does your business send out invoices to customers? Adding one line may make a huge impact for the Bitcoin economy. Perhaps you list it as a payment option just after Visa, MasterCard, and American Express, even if that means your customer must call or e-mail to make a payment.<br />
<br />
If you have access to the programming expertise such that you can generate Bitcoin addresses programmatically, consider generating a brand new Bitcoin address for each invoice, and print it on the invoice. When a Bitcoin payment arrives, you'll automatically know where it should arrive.<br />
<br />
Customers might wonder how much BTC they should pay in order to satisfy an invoice in full. Your invoice might suggest an amount. For example, if your invoice is for $100 and BTC's are currently worth $1.24 each, your invoice might suggest that it can be paid in full ''"with a payment of 80.65 BTC if paid by (date)"''.<br />
<br />
You might be able to anticipate the possibility that even though a Bitcoin address can be printed on an invoice or payment stub, that they are very cumbersome for most people to type, especially being a mix of uppercase and lowercase letters. However, you should probably still do it anyway. The customer is probably going to want some paper trail for his payment. Giving him a pre-printed payment stub with a pre-printed address will satisfy that, because the customer can independently and publicly prove through [[Block Explorer]] that the payment took place.<br />
<br />
Does your business have a website? On your invoice, consider allowing them to go to a special URL to get the address to make a Bitcoin payment just by typing in their invoice number. For example, ''ht<nowiki>tps://ww</nowiki>w.yoursite.com/paybtc'' with a form they can enter their invoice number, or just ''ht<nowiki>tps://ww</nowiki>w.yoursite.com/paybtc/60365'' for paying invoice #60365. This way, they can see the Bitcoin address, copy and paste it directly into their Bitcoin client.<br />
<br />
Use a brand new address for each invoice whenever possible, and use it only once. This benefits the customer as it removes any ambiguity as to which customer is making which payment and for which invoice.<br />
<br />
===Avoiding fraud===<br />
<br />
You should also consider the possible risk that fraudsters could send counterfeit invoices to your customers, and entice them to make a payment to a Bitcoin address they control, instead of you. While that isn't likely in general - it depends on how well a fraudster could find out who your customers are in the first place - it would certainly be an unpleasant situation if it ever happened. One way you could control that is, whenever possible, never let people try to type Bitcoin addresses off payment stubs - instead, force people to get the full Bitcoin address from your website via secure SSL. But, still print ''most'' of the address on the payment stub (perhaps with four or five characters starred out), so that the customer's need for a paper trail can be satisfied, so they can prove they paid if there is ever a dispute.<br />
<br />
==Setting Prices==<br />
<br />
When a business accepts bitcoins for payment, there generally is the need to convert them to the currencies used for paying suppliers, employees and shareholders. Some merchants set prices based on the current market rate at the time the price quote is presented to the customer (merchant services like [http://paysius.com Paysius] or [http://www.bit-pay.com Bit-pay] do this automatically). <br />
<br />
[[Bitcoin Prices]] lists the exchange rate for many currencies on multiple exchanges.<br />
<br />
When prices are determined using an automated process, the current market rate can be based on either a current price or on a weighted average basis. [[Bitcoin Charts]] provides a [http://bitcoincharts.com/about/markets-api data feed that provides weighted prices].<br />
<br />
When bitcoin funds for purchases are received, some merchants instantly exchange those proceeds into the preferred currency used (again done automatically by [http://paysius.com Paysius] or [http://www.bit-pay.com Bit-pay]). Hedging for each transaction can nearly entirely eliminate exchange rate risk that the business is exposed to when accepting bitcoins for payment.<br />
<br />
==Contract==<br />
<br />
A sales contract might be used to ensure that specific terms are met to lessen the chances of a misunderstanding. For instance, the party sending payment is responsible for paying any [[transaction fee]] that might be necessary. A contract might specify that a transaction fee must be paid and what amount, so as to prevent the situation where the transaction is considered a low priority transaction and thus isn't confirmed quickly.<br />
<br />
Other items that might be addressed in a contract:<br />
<br />
* Requirement and handling of escrow through an [[:Category:Escrow_services|escrow service]].<br />
* Jurisdiction for disputes.<br />
* Refund policy (particularly with the exchange rate being volatile)<br />
<br />
==Paying taxes on Bitcoin income==<br />
[[Tax compliance]] is a topic of concern for small businesses. We aren't accountants or lawyers, and can't give legal or accounting advice.<br />
<br />
But in many respects, Bitcoin transactions work very much like cash. Just like Bitcoin, cash is anonymous and doesn't leave a paper trail, yet is widely used in commerce every day.<br />
<br />
Ask yourself how you would handle a cash transaction. Do you accept cash transactions? Do you normally pay taxes on cash transactions? The answer for Bitcoin should probably be the same.<br />
<br />
As for how to decide what a Bitcoin transaction is worth... the IRS, as far as we know, has never issued a guide mentioning how to value Bitcoin transactions. But they probably have rules and guidelines on how to value transactions made in foreign currency or "cash equivalents". We imagine the accounting would be similar.<br />
<br />
With Bitcoins, there's likely to be some difference between the value of BTC when you received them as payment, versus when you go to exchange them for another currency like USD, should you decide to do so. This scenario, likewise, would be no different if you accepted foreign currency or gold as payment. Under some scenarios, it might make sense to book the dollar value of BTC income as it is received, and then to book any difference incurred when it is exchanged for fiat currency. Under others, it might make sense to book the whole thing at the time of exchange.<br />
<br />
Perhaps you might talk to your accountant. You don't need to get into a discussion with your accountant about block chains and private keys or the philosophy behind a decentralized currency. By comparing the fundamentals of Bitcoins to accounting concepts already well understood by the public, you can probably get all the answers you need. What would you ask your accountant if you decided that you wanted to accept ''Berkshire Bucks'' or 1-ounce gold coins as payment?<br />

<hr />
<div>This guide is intended for small business owners who wish to help promote Bitcoin by accepting it as payment for goods and services. It's written with the assumption that you operate a regular business that sells goods or services for regular national currency such as dollars, and that you wish to accept Bitcoin as another legal way to pay, and that you intend to pay taxes on your Bitcoin income just like any other income.<br />
<br />
With Bitcoin being touted as a way to conduct anonymous transactions and as way to compete with government currency, many small business owners wonder what's the right way to accept and account Bitcoin, or if it's legal or ethical, or whether and how they should pay taxes on income received through Bitcoin.<br />
<br />
As far as we know, Bitcoin isn't yet formally recognized by governments and authorities as a "currency". But in practice, Bitcoin is likely no different than accepting payment in other forms, such as cash, or gold, or scrip, or gift cards or foreign currency. We think that it is pretty much the same as the local businesses of Great Barrington, Massachusetts choosing to accept their locally-printed [http://www.reuters.com/article/2007/06/19/us-usa-economy-berkshares-idUSN0530157720070619 "Berkshire Bucks"] to support their local economy.<br />
<br />
==Starting to accept Bitcoin for transactions==<br />
Accepting Bitcoin at a small business is best started in whichever manner keeps the accounting simple for you. This will vary by the type of business you are operating.<br />
<br />
===Start with a sign===<br />
[[{{ns:file}}:WeAcceptBitcoin.png]]<br />
<br />
If you expect that the number of people interested in using Bitcoin is small, you might simply start by posting a sign or a note: "We Accept Bitcoin", and ask people to contact you directly in order to make a payment. Even if hardly anybody uses Bitcoin as a payment method, you're helping Bitcoin in two ways: one, by increasing awareness, and two, by making your customers more willing to accept Bitcoin as payment from others in the future, because now they know somewhere they can spend it.<br />
<br />
===Utilize a merchant solution===<br />
If you sell things on your website (goods or services), you'll want to use a [[#Merchant Services|Bitcoin merchant solution]] to accept the Bitcoins (you can usually opt to have them converted to USD or other currencies automatically). If you sell things in a brick and mortar shop, customers can pay using their mobile phone app (for example [http://www.paytunia.com Paytunia] or [http://www.blockchain.info/wallet Blockchain.info's app]), so it's best if you can place a QR code near your register to which the customers can scan with their phone and pay (use http://ma.eatgold.com/accept to make a QR code sign).<br />
<br />
===Accounting===<br />
When a customer makes a payment, you might simply issue a credit to their account. Ideally, you want to enter it in a way that suggests you received a payment. You could consider entering it as a "discount", but you may want to consider whether this inappropriately disguises the nature of the transaction. If on the other hand, you're giving "discounts" for Bitcoins, but then you are selling the Bitcoins for currency and then counting that as income, then chances are good that your calculation of income is making up for it. Ask your accountant.<br />
<br />
===Businesses that offer gift cards===<br />
If your business sells gift cards or gift certificates, you may find that the easiest way to accept Bitcoin is to accept it only for the purchase of gift cards, and then require the gift cards to be used for actual purchases of goods or services. This way, the accounting practices you already have in place for processing gift cards can be put to use. The accounting for Bitcoins would then be minimized to tracking sales of a single SKU.<br />
<br />
This method is also ideal for retail food establishments and convenience stores, where the payment of Bitcoins through a mobile phone for a small daily food purchase might be cumbersome or disruptive, especially in front of a line of other customers. Bitcoins in this case would be best used to reload prepaid cards that can then be swiped at point-of-sale.<br />
<br />
If you don't accept gift cards, but you already accept credit cards through a swipe terminal, consider the possibility that you could add a retail gift card system through the swipe terminal you already own. Many point-of-sale terminals, including ones from VeriFone&reg;, are designed around the ability to support multiple applications on the same terminal. Gift cards are also highly profitable because of "breakage", or in other words, the fact that a significant percentage of them never get redeemed.<br />
<br />
You could consider adding a private label gift card program from a provider who specializes in this, not just as a jumpstart to accepting Bitcoins, but as an extra boost to income. A private label gift card service provider necessarily have to handle your funds - they can simply provide a solution that keeps track of the balance on the cards on your behalf, including features that allow users to check their balances by phone or by web. Such a solution, of course, is also what makes the cards swipeable through the card reader.<br />
<br />
===Businesses that mail invoices===<br />
Does your business send out invoices to customers? Adding one line may make a huge impact for the Bitcoin economy. Perhaps you list it as a payment option just after Visa, MasterCard, and American Express, even if that means your customer must call or e-mail to make a payment.<br />
<br />
If you have access to the programming expertise such that you can generate Bitcoin addresses programmatically, consider generating a brand new Bitcoin address for each invoice, and print it on the invoice. When a Bitcoin payment arrives, you'll automatically know where it should arrive.<br />
<br />
Customers might wonder how much BTC they should pay in order to satisfy an invoice in full. Your invoice might suggest an amount. For example, if your invoice is for $100 and BTC's are currently worth $1.24 each, your invoice might suggest that it can be paid in full ''"with a payment of 80.65 BTC if paid by (date)"''.<br />
<br />
You might be able to anticipate the possibility that even though a Bitcoin address can be printed on an invoice or payment stub, that they are very cumbersome for most people to type, especially being a mix of uppercase and lowercase letters. However, you should probably still do it anyway. The customer is probably going to want some paper trail for his payment. Giving him a pre-printed payment stub with a pre-printed address will satisfy that, because the customer can independently and publicly prove through [[Block Explorer]] that the payment took place.<br />
<br />
Does your business have a website? On your invoice, consider allowing them to go to a special URL to get the address to make a Bitcoin payment just by typing in their invoice number. For example, ''ht<nowiki>tps://ww</nowiki>w.yoursite.com/paybtc'' with a form they can enter their invoice number, or just ''ht<nowiki>tps://ww</nowiki>w.yoursite.com/paybtc/60365'' for paying invoice #60365. This way, they can see the Bitcoin address, copy and paste it directly into their Bitcoin client.<br />
<br />
Use a brand new address for each invoice whenever possible, and use it only once. This benefits the customer as it removes any ambiguity as to which customer is making which payment and for which invoice.<br />
<br />
===Avoiding fraud===<br />
<br />
You should also consider the possible risk that fraudsters could send counterfeit invoices to your customers, and entice them to make a payment to a Bitcoin address they control, instead of you. While that isn't likely in general - it depends on how well a fraudster could find out who your customers are in the first place - it would certainly be an unpleasant situation if it ever happened. One way you could control that is, whenever possible, never let people try to type Bitcoin addresses off payment stubs - instead, force people to get the full Bitcoin address from your website via secure SSL. But, still print ''most'' of the address on the payment stub (perhaps with four or five characters starred out), so that the customer's need for a paper trail can be satisfied, so they can prove they paid if there is ever a dispute.<br />
<br />
==Setting Prices==<br />
<br />
When a business accepts bitcoins for payment, there generally is the need to convert them to the currencies used for paying suppliers, employees and shareholders. Some merchants set prices based on the current market rate at the time the price quote is presented to the customer (merchant services like [http://paysius.com Paysius] or [http://www.bit-pay.com Bit-pay] do this automatically). <br />
<br />
[[Bitcoin Prices]] lists the exchange rate for many currencies on multiple exchanges.<br />
<br />
When prices are determined using an automated process, the current market rate can be based on either a current price or on a weighted average basis. [[Bitcoin Charts]] provides a [http://bitcoincharts.com/about/markets-api data feed that provides weighted prices].<br />
<br />
When bitcoin funds for purchases are received, some merchants instantly exchange those proceeds into the preferred currency used (again done automatically by [http://paysius.com Paysius] or [http://www.bit-pay.com Bit-pay]). Hedging for each transaction can nearly entirely eliminate exchange rate risk that the business is exposed to when accepting bitcoins for payment.<br />
<br />
==Contract==<br />
<br />
A sales contract might be used to ensure that specific terms are met to lessen the chances of a misunderstanding. For instance, the party sending payment is responsible for paying any [[transaction fee]] that might be necessary. A contract might specify that a transaction fee must be paid and what amount, so as to prevent the situation where the transaction is considered a low priority transaction and thus isn't confirmed quickly.<br />
<br />
Other items that might be addressed in a contract:<br />
<br />
* Requirement and handling of escrow through an [[:Category:Escrow_services|escrow service]].<br />
* Jurisdiction for disputes.<br />
* Refund policy (particularly with the exchange rate being volatile)<br />
<br />

We think that it is pretty much the same as the local businesses of Great Barrington, Massachusetts choosing to accept their locally-printed [http://www.reuters.com/article/2007/06/19/us-usa-economy-berkshares-idUSN0530157720070619 "Berkshire Bucks"] to support their local economy.<br />
<br />
==Starting to accept Bitcoin for transactions==<br />
Accepting Bitcoin at a small business is best started in whichever manner keeps the accounting simple for you. This will vary by the type of business you are operating.<br />
<br />
===Start with a sign===<br />
[[{{ns:file}}:WeAcceptBitcoin.png]]<br />
<br />
If you expect that the number of people interested in using Bitcoin is small, you might simply start by posting a sign or a note: "We Accept Bitcoin", and ask people to contact you directly in order to make a payment. Even if hardly anybody uses Bitcoin as a payment method, you're helping Bitcoin in two ways: one, by increasing awareness, and two, by making your customers more willing to accept Bitcoin as payment from others in the future, because now they know somewhere they can spend it.<br />
<br />
===Utilize a merchant solution===<br />
If you sell things on your website (goods or services), you'll want to use a Bitcoin merchant solution (like [http://www.bitpay.com BitPay], [http://merchant.bitutils.com BitUtils], [https://mtgox.com/merchant MTGOX], [http://paysius.com Paysius], or [http://walletbit.com WalletBit]) to accept the Bitcoins (you can usually opt to have them converted to USD or other currencies automatically). If you sell things in a brick and mortar shop, customers can pay using their mobile phone app (for example [http://www.paytunia.com Paytunia] or [http://www.blockchain.info/wallet Blockchain.info's app]), so it's best if you can place a QR code near your register to which the customers can scan with their phone and pay (use http://ma.eatgold.com/accept to make a QR code sign).<br />
<br />
===Accounting===<br />
When a customer makes a payment, you might simply issue a credit to their account. Ideally, you want to enter it in a way that suggests you received a payment. You could consider entering it as a "discount", but you may want to consider whether this inappropriately disguises the nature of the transaction. If on the other hand, you're giving "discounts" for Bitcoins, but then you are selling the Bitcoins for currency and then counting that as income, then chances are good that your calculation of income is making up for it. Ask your accountant.<br />
<br />
===Businesses that offer gift cards===<br />
If your business sells gift cards or gift certificates, you may find that the easiest way to accept Bitcoin is to accept it only for the purchase of gift cards, and then require the gift cards to be used for actual purchases of goods or services. This way, the accounting practices you already have in place for processing gift cards can be put to use. The accounting for Bitcoins would then be minimized to tracking sales of a single SKU.<br />
<br />
This method is also ideal for retail food establishments and convenience stores, where the payment of Bitcoins through a mobile phone for a small daily food purchase might be cumbersome or disruptive, especially in front of a line of other customers. Bitcoins in this case would be best used to reload prepaid cards that can then be swiped at point-of-sale.<br />
<br />
If you don't accept gift cards, but you already accept credit cards through a swipe terminal, consider the possibility that you could add a retail gift card system through the swipe terminal you already own. Many point-of-sale terminals, including ones from VeriFone&reg;, are designed around the ability to support multiple applications on the same terminal. Gift cards are also highly profitable because of "breakage", or in other words, the fact that a significant percentage of them never get redeemed.<br />
<br />
You could consider adding a private label gift card program from a provider who specializes in this, not just as a jumpstart to accepting Bitcoins, but as an extra boost to income. A private label gift card service provider necessarily have to handle your funds - they can simply provide a solution that keeps track of the balance on the cards on your behalf, including features that allow users to check their balances by phone or by web. Such a solution, of course, is also what makes the cards swipeable through the card reader.<br />
<br />
===Businesses that mail invoices===<br />
Does your business send out invoices to customers? Adding one line may make a huge impact for the Bitcoin economy. Perhaps you list it as a payment option just after Visa, MasterCard, and American Express, even if that means your customer must call or e-mail to make a payment.<br />
<br />
If you have access to the programming expertise such that you can generate Bitcoin addresses programmatically, consider generating a brand new Bitcoin address for each invoice, and print it on the invoice. When a Bitcoin payment arrives, you'll automatically know where it should arrive.<br />
<br />
Customers might wonder how much BTC they should pay in order to satisfy an invoice in full. Your invoice might suggest an amount. For example, if your invoice is for $100 and BTC's are currently worth $1.24 each, your invoice might suggest that it can be paid in full ''"with a payment of 80.65 BTC if paid by (date)"''.<br />
<br />
You might be able to anticipate the possibility that even though a Bitcoin address can be printed on an invoice or payment stub, that they are very cumbersome for most people to type, especially being a mix of uppercase and lowercase letters. However, you should probably still do it anyway. The customer is probably going to want some paper trail for his payment. Giving him a pre-printed payment stub with a pre-printed address will satisfy that, because the customer can independently and publicly prove through [[Block Explorer]] that the payment took place.<br />
<br />
Does your business have a website? On your invoice, consider allowing them to go to a special URL to get the address to make a Bitcoin payment just by typing in their invoice number. For example, ''ht<nowiki>tps://ww</nowiki>w.yoursite.com/paybtc'' with a form they can enter their invoice number, or just ''ht<nowiki>tps://ww</nowiki>w.yoursite.com/paybtc/60365'' for paying invoice #60365. This way, they can see the Bitcoin address, copy and paste it directly into their Bitcoin client.<br />
<br />
Use a brand new address for each invoice whenever possible, and use it only once. This benefits the customer as it removes any ambiguity as to which customer is making which payment and for which invoice.<br />
<br />
===Avoiding fraud===<br />
<br />
You should also consider the possible risk that fraudsters could send counterfeit invoices to your customers, and entice them to make a payment to a Bitcoin address they control, instead of you. While that isn't likely in general - it depends on how well a fraudster could find out who your customers are in the first place - it would certainly be an unpleasant situation if it ever happened. One way you could control that is, whenever possible, never let people try to type Bitcoin addresses off payment stubs - instead, force people to get the full Bitcoin address from your website via secure SSL. But, still print ''most'' of the address on the payment stub (perhaps with four or five characters starred out), so that the customer's need for a paper trail can be satisfied, so they can prove they paid if there is ever a dispute.<br />
<br />
==Setting Prices==<br />
<br />
When a business accepts bitcoins for payment, there generally is the need to convert them to the currencies used for paying suppliers, employees and shareholders. Some merchants set prices based on the current market rate at the time the price quote is presented to the customer (merchant services like [http://paysius.com Paysius] or [http://www.bit-pay.com Bit-pay] do this automatically). <br />
<br />
[[Bitcoin Prices]] lists the exchange rate for many currencies on multiple exchanges.<br />
<br />
When prices are determined using an automated process, the current market rate can be based on either a current price or on a weighted average basis. [[Bitcoin Charts]] provides a [http://bitcoincharts.com/about/markets-api data feed that provides weighted prices].<br />
<br />
When bitcoin funds for purchases are received, some merchants instantly exchange those proceeds into the preferred currency used (again done automatically by [http://paysius.com Paysius] or [http://www.bit-pay.com Bit-pay]). Hedging for each transaction can nearly entirely eliminate exchange rate risk that the business is exposed to when accepting bitcoins for payment.<br />
<br />
==Contract==<br />
<br />
A sales contract might be used to ensure that specific terms are met to lessen the chances of a misunderstanding. For instance, the party sending payment is responsible for paying any [[transaction fee]] that might be necessary. A contract might specify that a transaction fee must be paid and what amount, so as to prevent the situation where the transaction is considered a low priority transaction and thus isn't confirmed quickly.<br />
<br />
Other items that might be addressed in a contract:<br />
<br />
* Requirement and handling of escrow through an [[:Category:Escrow_services|escrow service]].<br />
* Jurisdiction for disputes.<br />
* Refund policy (particularly with the exchange rate being volatile)<br />
<br />
==Paying taxes on Bitcoin income==<br />
[[Tax compliance]] is a topic of concern for small businesses. We aren't accountants or lawyers, and can't give legal or accounting advice.<br />
<br />
But in many respects, Bitcoin transactions work very much like cash. Just like Bitcoin, cash is anonymous and doesn't leave a paper trail, yet is widely used in commerce every day.<br />
<br />
Ask yourself how you would handle a cash transaction. Do you accept cash transactions? Do you normally pay taxes on cash transactions? The answer for Bitcoin should probably be the same.<br />
<br />
As for how to decide what a Bitcoin transaction is worth... the IRS, as far as we know, has never issued a guide mentioning how to value Bitcoin transactions. But they probably have rules and guidelines on how to value transactions made in foreign currency or "cash equivalents". We imagine the accounting would be similar.<br />
<br />
With Bitcoins, there's likely to be some difference between the value of BTC when you received them as payment, versus when you go to exchange them for another currency like USD, should you decide to do so. This scenario, likewise, would be no different if you accepted foreign currency or gold as payment. Under some scenarios, it might make sense to book the dollar value of BTC income as it is received, and then to book any difference incurred when it is exchanged for fiat currency. Under others, it might make sense to book the whole thing at the time of exchange.<br />
<br />
Perhaps you might talk to your accountant. You don't need to get into a discussion with your accountant about block chains and private keys or the philosophy behind a decentralized currency. By comparing the fundamentals of Bitcoins to accounting concepts already well understood by the public, you can probably get all the answers you need. What would you ask your accountant if you decided that you wanted to accept ''Berkshire Bucks'' or 1-ounce gold coins as payment?<br />

<hr />
<div>This guide is intended for small business owners who wish to help promote Bitcoin by accepting it as payment for goods and services. It's written with the assumption that you operate a regular business that sells goods or services for regular national currency such as dollars, and that you wish to accept Bitcoin as another legal way to pay, and that you intend to pay taxes on your Bitcoin income just like any other income.<br />
<br />
With Bitcoin being touted as a way to conduct anonymous transactions and as way to compete with government currency, many small business owners wonder what's the right way to accept and account Bitcoin, or if it's legal or ethical, or whether and how they should pay taxes on income received through Bitcoin.<br />
<br />
As far as we know, Bitcoin isn't yet formally recognized by governments and authorities as a "currency". But in practice, Bitcoin is likely no different than accepting payment in other forms, such as cash, or gold, or scrip, or gift cards or foreign currency. We think that it is pretty much the same as the local businesses of Great Barrington, Massachusetts choosing to accept their locally-printed [http://www.reuters.com/article/2007/06/19/us-usa-economy-berkshares-idUSN0530157720070619 "Berkshire Bucks"] to support their local economy.<br />

If you sell things in a brick and mortar shop, customers can pay using their mobile phone app (for example [http://www.paytunia.com Paytunia] or [http://www.blockchain.info/wallet Blockchain.info's app]), so it's best if you can place a QR code near your register to which the customers can scan with their phone and pay (use http://ma.eatgold.com/accept to make a QR code sign).<br />

This way, they can see the Bitcoin address, copy and paste it directly into their Bitcoin client.<br />
<br />
Use a brand new address for each invoice whenever possible, and use it only once. This benefits the customer as it removes any ambiguity as to which customer is making which payment and for which invoice.<br />
<br />
===Avoiding fraud===<br />
<br />
You should also consider the possible risk that fraudsters could send counterfeit invoices to your customers, and entice them to make a payment to a Bitcoin address they control, instead of you. While that isn't likely in general - it depends on how well a fraudster could find out who your customers are in the first place - it would certainly be an unpleasant situation if it ever happened. One way you could control that is, whenever possible, never let people try to type Bitcoin addresses off payment stubs - instead, force people to get the full Bitcoin address from your website via secure SSL. But, still print ''most'' of the address on the payment stub (perhaps with four or five characters starred out), so that the customer's need for a paper trail can be satisfied, so they can prove they paid if there is ever a dispute.<br />
<br />
==Setting Prices==<br />
<br />
When a business accepts bitcoins for payment, there generally is the need to convert them to the currencies used for paying suppliers, employees and shareholders. Some merchants set prices based on the current market rate at the time the price quote is presented to the customer (merchant services like [http://paysius.com Paysius] or [http://www.bit-pay.com Bit-pay] do this automatically). <br />
<br />
[[Bitcoin Prices]] lists the exchange rate for many currencies on multiple exchanges.<br />
<br />
When prices are determined using an automated process, the current market rate can be based on either a current price or on a weighted average basis. [[Bitcoin Charts]] provides a [http://bitcoincharts.com/about/markets-api data feed that provides weighted prices].<br />
<br />
When bitcoin funds for purchases are received, some merchants instantly exchange those proceeds into the preferred currency used (again done automatically by [http://paysius.com Paysius] or [http://www.bit-pay.com Bit-pay]). Hedging for each transaction can nearly entirely eliminate exchange rate risk that the business is exposed to when accepting bitcoins for payment.<br />
<br />
==Contract==<br />
<br />
A sales contract might be used to ensure that specific terms are met to lessen the chances of a misunderstanding. For instance, the party sending payment is responsible for paying any [[transaction fee]] that might be necessary. A contract might specify that a transaction fee must be paid and what amount, so as to prevent the situation where the transaction is considered a low priority transaction and thus isn't confirmed quickly.<br />
<br />
Other items that might be addressed in a contract:<br />
<br />
* Requirement and handling of escrow through an [[:Category:Escrow_services|escrow service]].<br />
* Jurisdiction for disputes.<br />
* Refund policy (particularly with the exchange rate being volatile)<br />
<br />
==Paying taxes on Bitcoin income==<br />
[[Tax compliance]] is a topic of concern for small businesses. We aren't accountants or lawyers, and can't give legal or accounting advice.<br />
<br />
But in many respects, Bitcoin transactions work very much like cash. Just like Bitcoin, cash is anonymous and doesn't leave a paper trail, yet is widely used in commerce every day.<br />
<br />
Ask yourself how you would handle a cash transaction. Do you accept cash transactions? Do you normally pay taxes on cash transactions? The answer for Bitcoin should probably be the same.<br />
<br />
As for how to decide what a Bitcoin transaction is worth... the IRS, as far as we know, has never issued a guide mentioning how to value Bitcoin transactions. But they probably have rules and guidelines on how to value transactions made in foreign currency or "cash equivalents". We imagine the accounting would be similar.<br />
<br />
With Bitcoins, there's likely to be some difference between the value of BTC when you received them as payment, versus when you go to exchange them for another currency like USD, should you decide to do so. This scenario, likewise, would be no different if you accepted foreign currency or gold as payment. Under some scenarios, it might make sense to book the dollar value of BTC income as it is received, and then to book any difference incurred when it is exchanged for fiat currency. Under others, it might make sense to book the whole thing at the time of exchange.<br />
<br />
Perhaps you might talk to your accountant. You don't need to get into a discussion with your accountant about block chains and private keys or the philosophy behind a decentralized currency. By comparing the fundamentals of Bitcoins to accounting concepts already well understood by the public, you can probably get all the answers you need. What would you ask your accountant if you decided that you wanted to accept ''Berkshire Bucks'' or 1-ounce gold coins as payment?<br />

[[Category:Local]]</div>JulianToshhttps://en.bitcoin.it/w/index.php?title=How_to_accept_Bitcoin,_for_small_businesses&diff=33656How to accept Bitcoin, for small businesses2012-12-12T13:57:58Z<p>JulianTosh: /* Utilize a merchant solution */</p>
<hr />
<div>This guide is intended for small business owners who wish to help promote Bitcoin by accepting it as payment for goods and services. It's written with the assumption that you operate a regular business that sells goods or services for regular national currency such as dollars, and that you wish to accept Bitcoin as another legal way to pay, and that you intend to pay taxes on your Bitcoin income just like any other income.<br />
<br />
With Bitcoin being touted as a way to conduct anonymous transactions and as way to compete with government currency, many small business owners wonder what's the right way to accept and account Bitcoin, or if it's legal or ethical, or whether and how they should pay taxes on income received through Bitcoin.<br />
<br />
As far as we know, Bitcoin isn't yet formally recognized by governments and authorities as a "currency". But in practice, Bitcoin is likely no different than accepting payment in other forms, such as cash, or gold, or scrip, or gift cards or foreign currency. We think that it is pretty much the same as the local businesses of Great Barrington, Massachusetts choosing to accept their locally-printed [http://www.reuters.com/article/2007/06/19/us-usa-economy-berkshares-idUSN0530157720070619 "Berkshire Bucks"] to support their local economy.<br />
<br />
==Starting to accept Bitcoin for transactions==<br />
Accepting Bitcoin at a small business is best started in whichever manner keeps the accounting simple for you. This will vary by the type of business you are operating.<br />
<br />
===Start with a sign===<br />
[[{{ns:file}}:WeAcceptBitcoin.png]]<br />
<br />
If you expect that the number of people interested in using Bitcoin is small, you might simply start by posting a sign or a note: "We Accept Bitcoin", and ask people to contact you directly in order to make a payment. Even if hardly anybody uses Bitcoin as a payment method, you're helping Bitcoin in two ways: one, by increasing awareness, and two, by making your customers more willing to accept Bitcoin as payment from others in the future, because now they know somewhere they can spend it.<br />
<br />
===Utilize a merchant solution===<br />
If you sell things on your website (goods or services), you'll want to use a Bitcoin merchant solution (like [http://paysius.com Paysius], [http://www.bit-pay.com Bit-pay], [http://merchant.bitutils.com BitUtils], or [http://walletbit.com WalletBit]) to accept the Bitcoins (you can usually opt to have them converted to USD or other currencies automatically). If you sell things in a brick and mortar shop, customers can pay using their mobile phone app (for example [http://www.paytunia.com Paytunia] or [http://www.blockchain.info/wallet Blockchain.info's app]), so it's best if you can place a QR code near your register to which the customers can scan with their phone and pay (use http://ma.eatgold.com/accept to make a QR code sign).<br />
<br />
===Accounting===<br />
When a customer makes a payment, you might simply issue a credit to their account. Ideally, you want to enter it in a way that suggests you received a payment. You could consider entering it as a "discount", but you may want to consider whether this inappropriately disguises the nature of the transaction. If on the other hand, you're giving "discounts" for Bitcoins, but then you are selling the Bitcoins for currency and then counting that as income, then chances are good that your calculation of income is making up for it. Ask your accountant.<br />
<br />
===Businesses that offer gift cards===<br />
If your business sells gift cards or gift certificates, you may find that the easiest way to accept Bitcoin is to accept it only for the purchase of gift cards, and then require the gift cards to be used for actual purchases of goods or services. This way, the accounting practices you already have in place for processing gift cards can be put to use. The accounting for Bitcoins would then be minimized to tracking sales of a single SKU.<br />
<br />
This method is also ideal for retail food establishments and convenience stores, where the payment of Bitcoins through a mobile phone for a small daily food purchase might be cumbersome or disruptive, especially in front of a line of other customers. Bitcoins in this case would be best used to reload prepaid cards that can then be swiped at point-of-sale.<br />
<br />
If you don't accept gift cards, but you already accept credit cards through a swipe terminal, consider the possibility that you could add a retail gift card system through the swipe terminal you already own. Many point-of-sale terminals, including ones from VeriFone&reg;, are designed around the ability to support multiple applications on the same terminal. Gift cards are also highly profitable because of "breakage", or in other words, the fact that a significant percentage of them never get redeemed.<br />
<br />
You could consider adding a private label gift card program from a provider who specializes in this, not just as a jumpstart to accepting Bitcoins, but as an extra boost to income. A private label gift card service provider necessarily have to handle your funds - they can simply provide a solution that keeps track of the balance on the cards on your behalf, including features that allow users to check their balances by phone or by web. Such a solution, of course, is also what makes the cards swipeable through the card reader.<br />
<br />
===Businesses that mail invoices===<br />
Does your business send out invoices to customers? Adding one line may make a huge impact for the Bitcoin economy. Perhaps you list it as a payment option just after Visa, MasterCard, and American Express, even if that means your customer must call or e-mail to make a payment.<br />
<br />
If you have access to the programming expertise such that you can generate Bitcoin addresses programmatically, consider generating a brand new Bitcoin address for each invoice, and print it on the invoice. When a Bitcoin payment arrives, you'll automatically know where it should arrive.<br />
<br />
Customers might wonder how much BTC they should pay in order to satisfy an invoice in full. Your invoice might suggest an amount. For example, if your invoice is for $100 and BTC's are currently worth $1.24 each, your invoice might suggest that it can be paid in full ''"with a payment of 80.65 BTC if paid by (date)"''.<br />
<br />
You might be able to anticipate the possibility that even though a Bitcoin address can be printed on an invoice or payment stub, that they are very cumbersome for most people to type, especially being a mix of uppercase and lowercase letters. However, you should probably still do it anyway. The customer is probably going to want some paper trail for his payment. Giving him a pre-printed payment stub with a pre-printed address will satisfy that, because the customer can independently and publicly prove through [[Block Explorer]] that the payment took place.<br />
<br />
Does your business have a website? On your invoice, consider allowing them to go to a special URL to get the address to make a Bitcoin payment just by typing in their invoice number. For example, ''ht<nowiki>tps://ww</nowiki>w.yoursite.com/paybtc'' with a form they can enter their invoice number, or just ''ht<nowiki>tps://ww</nowiki>w.yoursite.com/paybtc/60365'' for paying invoice #60365. This way, they can see the Bitcoin address, copy and paste it directly into their Bitcoin client.<br />
<br />
Use a brand new address for each invoice whenever possible, and use it only once. This benefits the customer as it removes any ambiguity as to which customer is making which payment and for which invoice.<br />
<br />
===Avoiding fraud===<br />
<br />
You should also consider the possible risk that fraudsters could send counterfeit invoices to your customers, and entice them to make a payment to a Bitcoin address they control, instead of you. While that isn't likely in general - it depends on how well a fraudster could find out who your customers are in the first place - it would certainly be an unpleasant situation if it ever happened. One way you could control that is, whenever possible, never let people try to type Bitcoin addresses off payment stubs - instead, force people to get the full Bitcoin address from your website via secure SSL. But, still print ''most'' of the address on the payment stub (perhaps with four or five characters starred out), so that the customer's need for a paper trail can be satisfied, so they can prove they paid if there is ever a dispute.<br />
<br />
==Setting Prices==<br />
<br />
When a business accepts bitcoins for payment, there generally is the need to convert them to the currencies used for paying suppliers, employees and shareholders. Some merchants set prices based on the current market rate at the time the price quote is presented to the customer (merchant services like [http://paysius.com Paysius] or [http://www.bit-pay.com Bit-pay] do this automatically). <br />
<br />
[[Bitcoin Prices]] lists the exchange rate for many currencies on multiple exchanges.<br />
<br />
When prices are determined using an automated process, the current market rate can be based on either a current price or on a weighted average basis. [[Bitcoin Charts]] provides a [http://bitcoincharts.com/about/markets-api data feed that provides weighted prices].<br />
<br />
When bitcoin funds for purchases are received, some merchants instantly exchange those proceeds into the preferred currency used (again done automatically by [http://paysius.com Paysius] or [http://www.bit-pay.com Bit-pay]). Hedging for each transaction can nearly entirely eliminate exchange rate risk that the business is exposed to when accepting bitcoins for payment.<br />
<br />
==Contract==<br />
<br />
A sales contract might be used to ensure that specific terms are met to lessen the chances of a misunderstanding. For instance, the party sending payment is responsible for paying any [[transaction fee]] that might be necessary. A contract might specify that a transaction fee must be paid and what amount, so as to prevent the situation where the transaction is considered a low priority transaction and thus isn't confirmed quickly.<br />
<br />
Other items that might be addressed in a contract:<br />
<br />
* Requirement and handling of escrow through an [[:Category:Escrow_services|escrow service]].<br />
* Jurisdiction for disputes.<br />
* Refund policy (particularly with the exchange rate being volatile)<br />

<div>= Terrorism =<br />
From the linked Wikipedia page:<br />
:The USA PATRIOT Act defines terrorism activities as "activities that (A) involve acts dangerous to human life that are a violation of the criminal laws of the U.S. or of any state, that (B) appear to be intended (i) to intimidate or coerce a civilian population, (ii) to influence the policy of a government by intimidation or coercion, or (iii) to affect the conduct of a government by mass destruction, assassination, or kidnapping, and (C) occur primarily within the territorial jurisdiction of the U.S."<br />
<br />
This definition is broad enough that it could probably be applied to the Bitcoin system. IANAL but I imagine lawyers could pretty easily demonstrate that Bitcoin is 'dangerous to human life' because the Four Horsemen can use it for evil [drug-dealers, money-launderers, terrorists, and pedophiles.] It can 'influence the policy of a government by coercion' by removing options such as Federal Reserve dollars. (C) might be tricky to prove.<br />

= Fractional Reserve Banking =<br />
<br />
I'd like to suggest a change here (translation: I fundamentally disagree with the tenor of the article). Credit Unions/Building Societies could quite easily be created, and this would increase the apparent amount of BTCs in existance, but it probably wouldn't exceed twice the original number.<br />
<br />
However, a bank functions differently: it creates a distinction between "hard money" (bank notes+coins) and "credit money" (money in bank accounts). So, in a bank I may deposit some real money (notes) but the bank effectively may lend some of that money to others AND I may also spend that money "in" my account by transferring it via a cheque or e-transfer to another person's account. (Building socities don't allow you to do that.)<br />
<br />
Now if I were to make a _BTC_ deposit into a "bank", then I wouldn't be able to spend the money in my "account" using conventional BTC trading (confirmations etc). No, what the bank would have to do is to set up a "virtual BTC" (vBTC) trading system, whereby they would manage accounts and transactions, and banks would owe each other v-BTCs depending on how their clients were deciding to spend/borrow their money. Banks could issue huge (virtually infinitie) amounts of v-BTCs depending on how risky they felt that morning.<br />
<br />
But then we'd be back to the present situation with fiat currencies, banks, treasury bills, etc etc. I guess it could be a new kind of "gold standard" - a "BTC standard". But the banks would still rule the world, and I thought we sought a way out of that....<br />
<br />
...maybe the ability of the user to transact BTC independently of any "fractional reserve banks" would keep a check on their potentially enormous power. But then if the number of v-BTCs was much more than real BTCs (as seems very likely if FRB took off - currently then ratio of v-GBPs to real GBPs is 20:1) then BTCs might end up so scarce in comparison that user trading in BTCs would no longer take place: it would all be in v-BTCs. All this make me think actually v-BTCs wouldn't work in the conventional way, and therefore that fraction reserve banking might not generate any more than 21m v-BTCs. I'd welcome help here.<br />
<br />
So my simple answer to the "Myth" question would be "FRB is possible, but "virtual BTCs" would be created, not real BTCs. [[User:Lawrence18uk|Lawrence18uk]] 19:47, 8 September 2011 (GMT)<br />
<br />
<br />
<br />
No no.. No v-BTCs are necessary for Fractional Reserve Banking at all. You can read how Fractional Reserve Banking works on [http://en.wikipedia.org/wiki/Fractional_reserve_banking#How_it_works Wikipedia]. Pay special attention to the "Example of deposit multiplication" section.<br />

= Fractional reserve banking with Bitcoin is fundamentally different =<br />
<br />
'''--------PeterSurda said the following-------'''<br />
<br />
My edit was removed only because someone disagrees with it, although they did not provide counterarguments. I did not claim that FRB is impossible, I claimed it is unlikely, due to lack of demand for Bitcoin substitutes. Without substitutes, FRB is impossible. '''Supply of Bitcoins cannot be increased beyond 21 million.''' The only thing that can be increased is the amount of Bitcoin substitutes, which are incompatible with Bitcoins. Demand for lending does not increase demand for Bitcoin substitutes. The argument presented by the author of the current text on the wiki is erroneous. It is impossible for a bank to accept a Bitcoin demand deposit and lend it simultaneously. It requires a creation of a Bitcoin-subsitute, for which there is no demand, because Bitcoins can exist in forms that other money, such as gold or fiat, require substitutes. [[User:PeterSurda|PeterSurda]] 09:28, 7 November 2011 (GMT)<br />
<br />
I rewrote FRB, hopefully it is more understandable now. I found the explanation of Atheros in my talk page so I was able to address it. [[User:PeterSurda|PeterSurda]] 23:44, 7 November 2011 (GMT)<br />
<br />
<br />
'''--------Atheros Response-------'''<br />
<br />
I (Atheros) have responded on your talk page and I will respond here as well.<br />
<br />
You are confused because you are confusing money supply with currency supply. Indeed, you are only using the word "supply". The currency supply is limited to 21 million bitcoins. The money supply is not. MtGox could tomorrow start lending out the hundreds of thousands of bitcoins they have in cold storage without adjusting the amount of bitcoins presented to users as available for withdrawal. They would maintain a reserve for the people who do withdraw bitcoins. We would then instantly have Fractional Reserve Banking. You need to give up this idea of substitutes that you keep using. Substitutes which are fundamentally different from Bitcoins are not necessary for fractional reserve banking. You've said several times on several talk pages that "Without substitutes, FRB is impossible" but need to explain what you mean by substitutes in the first place. The Wikipedia article on FRB, despite being very detailed, does not talk about substitutes.<br />
<br />
<br />
You said on my talk page that "With fiat dollars, the base money are the reserves the commercial banks have with the central bank"<br />
<br />
Why must the reserves be held at a central bank? I see no reason that this is necessary.<br />
<br />
<br />
<br />
You said: "Only the central bank can create the reserves. "<br />
<br />
What does this mean? If a commercial bank holds money in an account from which they do not lend out any money, then that money is held in reserve. No central bank is needed.<br />
<br />
<br />
<br />
You said: "With gold, banks take in gold bullion or coins, and provide either bank notes, account balances or cheques as substitutes. The banks in case of gold money cannot create more gold any more than in case of fiat money commercial banks cannot create more reserves."<br />
<br />
Ok, suppose they did not provide cheques or bank notes. Suppose that they only provided an account balance. I suppose you could call this account balance a substitute, but I've never heard it called such a thing. No one calls their bank account balance their "substitute dollars". For all intents and purposes, they consider their balance to be as good as dollars- indeed they can ''demand'' dollars at any time which is why the deposits made with the bank are called demand deposits.<br />
<br />
<br />
<br />
In response to the rest of your post on my talk page, you seem to be saying that because Bitcoin has no substitutes, then there cannot be FRB. My response is to say, first of all, that I'm just barely going along with your idea of a substitute anyway. I still don't see why having or not having substitutes has anything to do with FRB. But I will respond to your paragraph anyway because it contains a contradiction which makes winning this argument easy. You have previously defined that account balances (along with things like cheques) are substitutes, correct? And Bitcoins can be put in accounts, right? So then the user would be presented with an account balance, for example their MtGox balance, right? So there is your substitute! You have said that "The only way to do FRB is to present an alternative, a substitute, which of course is incompatible with Bitcoin". Thus we have a clear contradiction in your logic.<br />
<br />
<br />
I will now respond to your sentence: "Bitcoin Substitutes are required. Please explain how otherwise you can expand the supply without using magic."<br />
<br />
It is important to recognize the difference between Currency Supply and Money Supply. The currency supply of bitcoins is limited to 21 million. Money supply is higher because it includes demand deposits. Let us take an example: <br />
Suppose that there are only 100 Bitcoins on Earth all owned by Satoshi. He puts all 100 in Bank Alpha. Bank Alpha puts 20 of the bitcoins (20%) in a special account and leaves them there. They then lend out 80 bitcoins to Gavin. Bank Alpha tells Satoshi on his account page that his account has 100 bitcoins in it. The total money supply of Bitcoins at this point is 180. You can see that there is no magic required. Now, Gavin buys some LolCat comics from Cameron for 80 bitcoins. Cameron puts his 80 bitcoins in his bank, Bank Beta. Bank Beta puts 20% in reserve (16 bitcoins) and has 64 to lend out. They lend those 64 bitcoins to someone else. Cameron's account page on Bank Beta's website says he has 80 bitcoins in his account. The money supply of bitcoin is now 100+80+64 = 244 bitcoins. Supposing all banks put 20% in reserves for safe keeping, and suppose everyone uses banks (as opposed to keeping them in a wallet on their computer) then the money supply of bitcoin will max out at 500 bitcoins. Obviously because some people will hold their own bitcoins and because they will be used out in the world for transactions, the money supply wouldn't reach 500 bitcoins, but it can easily exceed 100. <br />
<br />
An obvious response is 'Well what happens when Gavin takes his bitcoins out of the bank!?'<br />
The answer is that that is what the reserves are for. '''Although not reflected in this example, the actual reserves held by a bank would be vastly greater than the amount held in any individual customer's account'''.<br />
<br />
And that is how Fractional Reserve Banking works.<br />
<br />
To avoid an edit war on the wiki page, I have put in a temporary message which I believe is neutral.<br />

'''--------PeterSurda Response-------'''<br />
<br />
<blockquote>You are confused because you are confusing money supply with currency supply.</blockquote><br />
Your alleged distinction between "money supply" and "currency supply" is bogus. Please look at the wikipedia page about Money supply: http://en.wikipedia.org/wiki/Money_supply <br />
<br />
<blockquote>MtGox could tomorrow start lending out the hundreds of thousands of bitcoins they have in cold storage without adjusting the amount of bitcoins presented to users as available for withdrawal.</blockquote><br />
You fail to address my point that this requires that these balances need to be accepted as if they were real bitcoin. That's not the case. It is explained in the wikipedia page: http://en.wikipedia.org/wiki/Metal_as_money :<br />
<br />
<blockquote>Money must be a tangible asset while a money substitute may be only a claim on a tangible asset. Either money or a money substitute may circulate as currency.</blockquote><br />
<br />
This matches exactly your descriptions of fictional FRB-Mt. Gox activies: they provide to borrowers claims on bitcoin: Mt.Gox account balances. Only if someone else accepts these balances instead of Bitcoin, would the FRB have an effect on the money supply.<br />
<br />
<blockquote>Why must the reserves be held at a central bank? I see no reason that this is necessary.</blockquote><br />
The reason why commercial banks cannot create fiat reserves is that it's illegal: only central banks are permitted to do that. They allow commercial banks to use these reserves and issue substitutes (e.g. bank account balances) upon that. The physical currency (notes and coins) is, in case of fiat, merely a distraction. Typically, the bank notes and coins are also issued only by the central bank, but in small exceptions, private banks are allowed to do that too (e.g. Scotland, Northern Ireland, Hong Kong). In the latter case, these are however also only substitutes: the issuing bank must redeem them to legal tender upon request. Please read the wikipedia page on Reserve requirements: http://en.wikipedia.org/wiki/Reserve_requirement . Of course, a commercial bank can create their own fiat currency, let's call them Rothbards. But that's not the case we are discussing.<br />
<br />
<blockquote>No one calls their bank account balance their "substitute dollars"</blockquote><br />
Economists do.<br />
<br />
<blockquote>For all intents and purposes, they consider their balance to be as good as dollars- indeed they can demand dollars at any time which is why the deposits made with the bank are called demand deposits.</blockquote><br />
However, they only do this because they know that if they use EFT or cheque, the recipient will accept it as if it was money proper. There is no way of creating cheques or bank account balances with fiat money or gold that does not involve substitutes, and because these have sometimes lower transaction costs, this creates demand for these substitutes. With Bitcoin, the requirement for such substitutes is absent (or, better said, limited).<br />
<br />
<blockquote>you seem to be saying that because Bitcoin has no substitutes, then there cannot be FRB.</blockquote><br />
I did not say FRB or substitutes with Bitcoin are impossible, on the contrary, I provided examples of both FRB and substitutes as such. I just explained why it is difficult to conduct in in a profitable manner, unlike with fiat and gold.<br />
<br />
<blockquote>My response is to say, first of all, that I'm just barely going along with your idea of a substitute anyway.</blockquote><br />
Money substitutes are not "my idea", these are terms by many economic schools and even the legal system. I merely merged various facts into a unique arrangement.<br />
<br />
<blockquote>I still don't see why having or not having substitutes has anything to do with FRB.</blockquote><br />
Let's say I have 100 BTC. How can I increase the money supply to 200? Only by promising to my customers "I will redeem up to 200 BTC". This is a claim they have on me, i.e. a money substitute I issued. If these claims are accepted as if they were money proper, they can circulate, and increase the money supply. If they do not circulate, they cannot increase money supply, they can only make me bankrupt (or a rich scammer).<br />
<br />
<blockquote>You have previously defined that account balances (along with things like cheques) are substitutes, correct? And Bitcoins can be put in accounts, right?</blockquote><br />
Poor choice of words on my part I am afraid. I said that "Bitcoin is the equivalent of a bank deposit". I should have written rather something like "Bitcoin is functionally similar to a bank account".<br />
<br />
<blockquote>So then the user would be presented with an account balance, for example their MtGox balance, right?</blockquote><br />
Bitcoin Mt.Gox balance is a substitute: it is an entry in their database that represents a claim on their reserves, an actual Bitcoin wallet. You cannot transfer this substitute outside of Mt.Gox' systems, i.e. they do not circulate. Even withdraw methods like green addresses and redeemable codes are Bitcoin rather than substitutes.<br />
<br />
<blockquote>They then lend out 80 bitcoins to Gavin. Bank Alpha tells Satoshi on his account page that his account has 100 bitcoins in it. The total money supply of Bitcoins at this point is 180.</blockquote><br />
The total account balances indeed list 180. However, this only increases money supply if someone is willing to accept these fractional balances as if they were real Bitcoin. But you can't do anything with them. In order to use them, you need an account in Bank Alpha. For people that do not have an account with Bank Alpha, these balances are not only worth less, they are unusable (incompatible with Bitcoin network). And even if there was Bank Beta that accepted it, these two banks would need to agree upon a way of settling these balances, and promise not to redeem other banks' deposits against real Bitcoin. This works with fiat and gold because there is no alternative to these settlements, and it can increase banks profits. With Bitcoin, it would just increase the costs so banks cannot gain anything in participating in something like this.<br />
<br />
<blockquote>And that is how Fractional Reserve Banking works.</blockquote><br />
You omit the point where the substitutes need to be accepted as if they were money proper, which is the basis of argument.<br />
<br />
<blockquote>To avoid an edit war on the wiki page, I have put in a temporary message which I believe is neutral.</blockquote><br />
Thank you, I prefer to have it clarified instead of an edit war too.<br />
<br />
Let's say I store Bitcoins and instead provide you "Surdas", which will be denominated in BTC. You can only use Surdas in my "bank". Bitcoin users cannot send or receive Surdas because they are incompatible with their systems. Let's say I collect 100BTC from you, and issue you a trillion Surdas. Will that increase the money supply of the Bitcoin economy?<br />

<blockquote>Let's say I collect 100BTC from you, and issue you a trillion Surdas. Will that increase the money supply of the Bitcoin economy?</blockquote><br />
<br />
No. The money supply would be the number-of-bitcoins-in-existance + 1 Trillion Surdas.<br />
<br />
<blockquote>Your alleged distinction between "money supply" and "currency supply" is bogus. Please look at the wikipedia page about Money supply: http://en.wikipedia.org/wiki/Money_supply"</blockquote><br />
<br />
Why? You did not say why. I am very familiar with Money supply. Perhaps instead of currency supply, I should say monetary base since there is a Wikipedia article on "Monetary Base". <br />
<br />
<blockquote>You fail to address my point that this requires that these balances need to be accepted as if they were real bitcoin. That's not the case. It is explained in the wikipedia page: http://en.wikipedia.org/wiki/Metal_as_money </blockquote><br />
<br />
The Wikipedia article "Metal as Money" is garbage, as evidenced by all the tags at the top. The article does not cite any sources. I see now why you keep talking about money substitutes. <br />
<br />
The balances to not need to be accepted by anyone except the holder of the account. The balances to not need to be transferred by cheque or EFT.<br />
<br />
<blockquote>Gox activies: they provide to borrowers claims on bitcoin: Mt.Gox account balances. Only if someone else accepts these balances instead of Bitcoin, would the FRB have an effect on the money supply. </blockquote><br />
<br />
No, you misunderstand. They don't provide borrowers claims on bitcoins. They provide real bitcoins. <br />
<br />
<br />
<blockquote>I said "Why must the reserves be held at a central bank? I see no reason that this is necessary."<br />
<br />
You responded: "The reason why commercial banks cannot create fiat reserves is that it's illegal: only central banks are permitted to do that."</blockquote><br />
<br />
You and I are using the word reserves differently. You are using it to mean a reserve of the monetary base. But that is not what reserves means in the context of Fractional Reserve Banking. Reserves can and often are held by commercial banks. Even the top of the "Reserve Requirements" Wikipedia page to which you link says that "It is normally in the form of cash stored physically in a bank vault (vault cash) or deposits made with a central bank." If you want to talk about holding gold or even fiat money in reserves at a central bank, you can, but that is not what reserves are in the context of Fractional Reserve Banking. <br />
<br />
<blockquote>I said: "No one calls their bank account balance their "substitute dollars""<br />
You said: "Economists do."</blockquote><br />
<br />
No they don't. Economists call them [http://en.wikipedia.org/wiki/Demand_deposit Demand deposits].<br />
<br />
<blockquote>However, they only do this because they know that if they use EFT or cheque, the recipient will accept it as if it was money proper.</blockquote><br />
<br />
No, people consider the money in their bank account to be as good as dollars in their hands because they can access the money on demand. Cheques and EFTs need not be involved.<br />
<br />
<blockquote>Money substitutes are not "my idea", these are terms by many economic schools and even the legal system.</blockquote><br />
<br />
It is not mainstream. The one article that talks about substitutes to which you linked on Wikipedia is slanted, unbalanced, disputed, contains original research, and lacks citations. <br />
<br />
<blockquote>"If these claims are accepted as if they were money proper, they can circulate, and increase the money supply. If they do not circulate, they cannot increase money supply"</blockquote><br />
<br />
False. Money does not need to be in circulation to increase the money supply. It can be stored in bank accounts. Bank accounts contain demand deposits. Demand deposits are included in the money supply. It annoys me that you wouldn't know this despite telling ''me'' to read the article on money supply. Here are the very first two lines: "In economics, the money supply or money stock, is the total amount of money available in an economy at a specific time.[1] There are several ways to define "money," but standard measures usually include currency in circulation and demand deposits (depositors' easily accessed assets on the books of financial institutions)."<br />
<br />
<br />
<blockquote>You said: "The total account balances indeed list 180. However, this only increases money supply if someone is willing to accept these fractional balances as if they were real Bitcoin."</blockquote><br />
<br />
No, you misunderstand. When I said that Bank Alpha lends out Bitcoins, I meant it. Bank Alpha does not lend out Bitcoin Substitutes, they lend out Bitcoins. <br />
<br />
You have admitted that the account balances in the example total 180. Therefore you have admitted that demand deposits are equal to at least 180 bitcoins. Money supply is defined as "currency in circulation and demand deposits (depositors' easily accessed assets on the books of financial institutions)." Therefore Money supply is greater than or equal to 180 bitcoins at that point in the example.<br />
<br />
I have countered your claims and answered your questions. I have provided an example of Fractional Reserve Banking with Bitcoins. Fractional Reserve Banking with Bitcoins is possible.<br />

<blockquote>No. The money supply would be the number-of-bitcoins-in-existance + 1 Trillion Surdas.</blockquote><br />
Exactly. The issue of Surdas would have no effect on the Bitcoin economy, unless someone accepted Surdas instead of Bitcoins. That's my whole point.<br />
<br />
<blockquote>Why? You did not say why. I am very familiar with Money supply. Perhaps instead of currency supply, I should say monetary base since there is a Wikipedia article on "Monetary Base".</blockquote><br />
You first need to define these two terms in a coherent manner, which has not happened.<br />
<br />
<blockquote>The Wikipedia article "Metal as Money" is garbage, as evidenced by all the tags at the top. The article does not cite any sources. I see now why you keep talking about money substitutes.</blockquote><br />
That does not disprove my point. I could have just as well quoted Mises' Human Action or Theory of Money and Credit, http://mises.org/books/Theory_Money_Credit/Part1_Ch3.aspx<br />
<br />
<blockquote>The balances to not need to be accepted by anyone except the holder of the account. The balances to not need to be transferred by cheque or EFT.</blockquote><br />
In order to increase the money supply, they do. You admitted this yourself in my example with Surdas vs. Bitcoins. Now, lets' get one step back and ask ourselves, why would the account holder accept such a weird instrument in the first place if he knew noone would accept it? It provides him no advantage over what he already has.<br />
<br />
<blockquote>No, you misunderstand. They don't provide borrowers claims on bitcoins. They provide real bitcoins.</blockquote><br />
In that case, they need to provide the claims (=substitute) to the lender. It's logically impossible to provide real bitcoins in excess of the reserves.<br />
<br />
<blockquote>You are using it to mean a reserve of the monetary base. But that is not what reserves means in the context of Fractional Reserve Banking.</blockquote><br />
Of course it does. Wikipedia page on Bank reserves, http://en.wikipedia.org/wiki/Bank_reserves , says:<br />
<br />
<blockquote>Bank reserves are banks' holdings of deposits in accounts with their central bank (for instance the European Central Bank or the Federal Reserve, in the latter case including federal funds), plus currency that is physically held in the bank's vault (vault cash).</blockquote><br />
And, since the currency is also issued by the central banks, that closes the circle.<br />
<br />
<blockquote>Reserves can and often are held by commercial banks.</blockquote><br />
This has no effect on my claim.<br />
<br />
<blockquote>Even the top of the "Reserve Requirements" Wikipedia page to which you link says that "It is normally in the form of cash stored physically in a bank vault (vault cash) or deposits made with a central bank." If you want to talk about holding gold or even fiat money in reserves at a central bank, you can, but that is not what reserves are in the context of Fractional Reserve Banking.</blockquote><br />
This does not negate the fact that both cash and central bank deposits are, in fact, created by the central bank.<br />
<br />
<blockquote>No they don't. Economists call them Demand deposits.</blockquote><br />
Demand deposits are a subset of money substitutes. Read the aforementioned chapter from Mises' book.<br />
<br />
<blockquote>No, people consider the money in their bank account to be as good as dollars in their hands because they can access the money on demand. Cheques and EFTs need not be involved.</blockquote><br />
If they do not deposit the money in the bank, then it is also accessible on demand. Therefore, if your argument was correct, there would be no demand for bank deposits in the first place and banks would not exist. Your reasoning is therefore erroneous.<br />
<br />
<blockquote>It is not mainstream.</blockquote><br />
The term might not be mainstream, but the concepts are. Even the article about Demand deposits you reference explains what it is. It says "These account balances are <b>usually</b> considered money and form the greater part of the money supply of a country." (emphasis added). However, it does not explain why. I provide an explanation. You just assume that there's some magic behind this, yet don't provide an explanation.<br />
<br />
<blockquote>Money does not need to be in circulation to increase the money supply.</blockquote><br />
You phrase it wrongly. If it is not in circulation, it is not money in the first place. It is just some financial instrument. Like my Surdas.<br />
<br />
<blockquote>Demand deposits are included in the money supply.</blockquote><br />
Wrong. Even the article you quote says "usually". You just assume that this is always true for some magical reason. It isn't, but until Bitcoin, it was not apparent. I explained the reason: the deposits are accepted as a method of payment, because there are situations where they provide lower transaction costs than the money proper, and with fiat/gold, this requires substitutes.<br />
<br />
<blockquote>It annoys me that you wouldn't know this despite telling me to read the article on money supply.</blockquote><br />
And it annoys me that you miss the big gap in your reasoning, although I have been pointing to it since my first edit.<br />
<br />
<blockquote>Here are the very first two lines: "In economics, the money supply or money stock, is the total amount of money available in an economy at a specific time.[1] There are several ways to define "money," but standard measures <b>usually</b> include currency in circulation and demand deposits (depositors' easily accessed assets on the books of financial institutions)."</blockquote><br />
(emphasis added) Again, you miss the gap in your reasoning. Even here, it says "usually". You just jump to the conclusion that it is always like this. It's not and I explained several times why.<br />
<br />
<blockquote>When I said that Bank Alpha lends out Bitcoins, I meant it. Bank Alpha does not lend out Bitcoin Substitutes, they lend out Bitcoins.</blockquote><br />
In that case, it is the lender that receives the substitute, which noone accepts. So he has no reason to deposit the money in the first place and Bank Alpha would not come to existence.<br />
<br />
<blockquote>Money supply is defined as "currency in circulation and demand deposits (depositors' easily accessed assets on the books of financial institutions)." Therefore Money supply is greater than or equal to 180 bitcoins at that point in the example.</blockquote><br />
Again, gap in reasoning, I already explained it several times. Merely because demand deposits form money supply with gold and fiat, it does not follow it works the same way with Bitcoin. You do not understand why economists include them in the definition of money supply in the first place.<br />
<br />
<blockquote>I have countered your claims and answered your questions.</blockquote><br />
You make systematic errors in your claims. You also fail to answer the core question, why are money substitutes such as demand deposits considered a part of the money supply in the first place.<br />
<br />
<blockquote>I have provided an example of Fractional Reserve Banking with Bitcoins. Fractional Reserve Banking with Bitcoins is possible.</blockquote><br />
For the last time, I did not claim FRB with Bitcoin was impossible. I even provided actual empirical evidence of it, unlike you. You have obviously no idea what you're talking about.<br />

'''Money supply''' is amount of currency in circulation plus demand deposits (depositors' easily <br />
<br />
accessed assets on the books of financial institutions).<br />
<br />
Apparently you do not accept this definition (more on this below). <br />
<br />
The '''monetary base''' is highly liquid money that consists of coins, paper money (both as <br />
<br />
bank vault cash and as currency circulating in the public), and commercial banks' reserves. <br />
<br />
In the case of Bitcoin, this would be ''real'' Bitcoins which are limited to 21 million.<br />
<br />
Do you accept this definition?<br />
<br />
Here is a helpful table. Monetary Base is MB and Money Supply is M1.<br />

<br />
I can give you two examples that currently or formerly exist that show that people do demand bank deposits despite not having substitutes like cheques and EFTs: MyBitcoin and MtGox. People hold/held quite a bit of money in these services. There would be further demand for deposit accounts if banks offer a bit of interest payment.

<br />
<blockquote>I said: "Demand deposits are included in the money supply."<br />

<br />
So do you assert that demand deposits are not included in the money supply as it applys to bitcoin? Edit: You stated this clearly in the rest of your post. I'm glad we are close to identifying the reason we disagree. I will address this in my next post after you respond.<br />
<br />
<blockquote>You said "In that case, it is the lender that receives the substitute, which no one accepts. So he has no reason to deposit the money in the first place and Bank Alpha would not come to existence."</blockquote><br />
<br />
Why would Bank Alpha receive substitutes? As I explained in the example, Bank Alpha receives Bitcoins!<br />
<br />
<blockquote>"You do not understand why economists include them in the definition of money supply in the first place."</blockquote><br />
<br />
Ok, Why is that? And why would it be any different for Bitcoin?<br />
<br />
<blockquote>"For the last time, I did not claim FRB with Bitcoin was impossible. I even provided actual empirical evidence of it, unlike you. You have obviously no idea what you're talking about."</blockquote><br />
<br />
I provided an example of Fractional Reserve Banking above! You didn't say that FRB is impossible but you did say that "Without demand for Bitcoin-substitutes, FRB is not possible." You also said, "If someone tried Bitcoin FRB, they would produce Bitcoin-substitutes: digital services or physical goods incompatible with the Bitcoin network, fiat money or gold. Who would accept something like that for payment?"<br />
<br />
Doesn't that clearly suggest that FRB with Bitcoin isn't realistically happening?<br />
<br />
<br />
I have asked several questions (this last one being the least important). I look forward to hearing your response.<br />
<br />
--[[User:Atheros|Atheros]]<br />
<br />
'''--------PeterSurda Response-------'''<br />
<br />
Let's put our arguments into a formal structure.<br />
<br />
Issue 1: definition of money supply:<br />
<br />
* Atheros: Zero maturity is a necessary and sufficient condition for a claim to be considered a part of the money supply.<br />
* PeterSurda: Both parts are incorrect. The necessary and sufficient condition is acceptance of the claim as a means of payment instead of the base.<br />
<br />
Proof:<br />
* there are claims which have zero maturity, and are not considered a part of the money supply. The best example I could think of are casino chips. They are zero maturity, but do not increase money supply regardless of whether they are backed by full or fractional reserves. Mt. Gox accounts are the equivalent of the casino chips: you can use them to exchange against other currencies on Mt.Gox' systems, and you can withdraw BTC. Other example I found are certain promissory notes.<br />
* even demand deposits do not always have zero maturity. Banks typically request a prior notice if you want to withdraw larger amount of cash, however require no such notice if you just want to transfer money out via EFT.<br />
<br />
Issue 2: application of the definition of money supply:<br />
<br />
* Atheros: money supply is cash (including one held by public and bank reserves) and demand deposits. Money supply increases when banks lend reserves.<br />
* PeterSurda: these two claims contradict each other.<br />
<br />
Proof:<br />
{| border="1"<br />
|+ Money supply calculation<br />
| Stage || Cash held by public || Demand deposits || Bank reserves || Money supply if demand deposit is not acceptable for payment || Money supply if demand deposit is acceptable for payment || Sum (cash + demand deposits)<br />
|-<br />
| Prior to deposit || 100||0||0||100||100||100<br />
|-<br />
| Creation of deposit ||0||100||100||100||100||200<br />
|-<br />
| Fractional reserve lending ||80||100||20||100||180||200<br />
|-<br />
| Creation of another deposit ||0||180||100||100||180||280<br />
|-<br />
| Additional fractional reserve lending ||60||180||40||100||240||280<br />
|}<br />
<br />
Clearly, the sums in last two columns are different. So either your description of FRB is wrong, our your definition of money supply.<br />
<br />
Issue 3: Usage of services:<br />
<br />
*Atheros: People deposit money into Mt. Gox. or mybitcoin (well, at least until it went belly up). These balances are demand deposits and therefore considered part of the money supply.<br />
*PeterSurda: Being a demand daposit does not mean it increases the money supply. Only if they circulate. As far as I know, Mt.Gox does not even support P2P payments outside of the BTC network, and I think mybitcoin did, but of course this only works among mybitcoin customers. Flexcoin supports this too, but I think Strongcoin does not. Furthermore, acording to your definition of the money supply (see previous table), if Satoshi deposited a million Bitcoins into Mt.Gox, that act of depositing would increase the money supply of bitcoins by about 13%, regardless of what Mt.Gox did with their reserves! Clearly there is something fishy about this.<br />
<br />
Issue 4: Effect of FRB on Bitcoin:<br />
<br />
*Atheros: PeterSurda claims that FRB with Bitcoin won't happen.<br />
*PeterSurda: I claim that FRB with Bitcoin has very little effect on money supply and is unprofitable.<br />

<br />
Issue 1: definition of money supply: <br />
<br />
I thought I gave a pretty clear definition of money supply: The amount of currency in circulation plus demand deposits (depositors' easily accessed assets on the books of financial institutions). The only reason casino chips aren't part of "the money supply" is because you haven't defined "the money supply". If by "the money supply" you mean "the money supply of casino chips" then casino chips are indeed part of the money supply (of casino chips). <br />
<br />
Your definition of money supply: "The necessary and sufficient condition is acceptance of the claim as a means of payment '''instead''' of the base." (emphasis added)<br />
<br />
What does this 'instead of the base' mean? Bitcoins are the monetary base of Bitcoin. Doesn't your definition mean that Bitcoins are not part of money supply?<br />
<br />
Issue 3: Usage of services (related to issue 1):<br />
<br />
I think it is goofy that you say that "being a demand deposit does not mean it increases the money supply". Let us suppose you have 100 bitcoins in your computer wallet and 100 bitcoins in MtGox in case you want to trade them some day. Wouldn't you say that you own 200 bitcoins? Wouldn't any reasonable person say that they own 200 bitcoins? Why, then, should the money supply be only 100 bitcoins? Why on Earth would the money supply go down when you move bitcoins from your computer to MtGox? <br />
<br />
In reply to your "fishy" comment- As I've said, the money supply is currency in circulation plus demand deposits. If Satoshi moves a million Bitcoins from his wallet (which are 'in circulation') to a demand deposit, the money supply stays the same. <br />
<br />
Issue 2: application of the definition of money supply: <br />
<br />
There are problems with your table. <br />
*The reason the last two columns are not equal is because you added bank reserves in your sum. Bank reserves are not included in M1 (money supply) which you can see in my table above in the ''minimum reserves and excess reserves'' row. <br />
*Demand deposits are never accepted as payment so having two columns to address this doesn't make sense. That said, the values you have in the column ''Money supply if demand deposit is acceptable for payment'' are correct. The only thing that is accepted in the case of Bitcoin is bitcoins. A person can either withdraw the bitcoins himself and give them to someone else, or he can instruct his bank to move the bitcoins from his account to someone else's. Here is the corrected table:<br />
<br />
{| border="1"<br />
|+ Money supply calculation<br />
| Stage || Cash held by public || Demand deposits || Bank reserves || Money supply <br />

<blockquote>I thought I gave a pretty clear definition of money supply: The amount of currency in circulation plus demand deposits (depositors' easily accessed assets on the books of financial institutions).</blockquote><br />
No, that's not what you said, you also included bank reserves. You also quoted sources that include bank reserves as money supply, including the description and the tables. You contradict that now.<br />
<br />
<blockquote>The only reason casino chips aren't part of "the money supply" is because you haven't defined "the money supply".</blockquote><br />
According to your justification for demand deposits being a part of money supply (zero maturity claim), casino chips should also be a part of the money supply. Can you address this?<br />
<br />
<blockquote>If by "the money supply" you mean "the money supply of casino chips" then casino chips are indeed part of the money supply (of casino chips).</blockquote><br />
The question is not what I mean, but what you mean.<br />
<br />
<blockquotE>What does this 'instead of the base' mean?</blockquote><br />
I've been talking about this since the beginning, it looks like you're finally coming around to confront it. It means that whoever you are sending money to is willing to accept this claim instead of accepting Bitcoins. Like cheque or EFT instead of cash, or (on gold standard) banknote instead of a gold coin.<br />
<br />
<blockquote> Bitcoins are the monetary base of Bitcoin. Doesn't your definition mean that Bitcoins are not part of money supply?</blockquote><br />
Read what I wrote. I did not say that the base (Bitcoin) is not the part of money supply, I wrote that claims on Bitcoin are only a part of the money supply if they are an accepted method of payment.<br />
<br />
<blockquote>I think it is goofy that you say that "being a demand deposit does not mean it increases the money supply".</blockquote><br />
I think it's regrettable that you still don't understand this.<br />
<br />
<blockquote>Let us suppose you have 100 bitcoins in your computer wallet and 100 bitcoins in MtGox in case you want to trade them some day. Wouldn't you say that you own 200 bitcoins?</blockquote><br />
You own 100 bitcoins and a claim on 100 bitcoins. This claim is only a part of money supply if you can use it for payment. At the moment, you can't. While it is hypothetically possible to use this claim as a method of payment in the future, there is no demand for it, unlike the situation with fiat and gold.<br />
<br />
<blockquote>Why, then, should the money supply be only 100 bitcoins?</blockquote><br />
I already explained it several times: for the same reason that owning 100 USD's worth of casino chips is not a part of the money supply of USD: they are not acceptable for payment. The "reserves" of the casino, however, in the absence of FRB, are a part of the money supply. So in your case the money supply is 200 BTC: 100 Bitcoins in your own wallet plus 100 Bitcoins as Mt.Gox reserves. The account balance you have with Mt.Gox does not appear in the equation.<br />
<br />
<blockquote>Why on Earth would the money supply go down when you move bitcoins from your computer to MtGox?</blockquote><br />
They money supply does not go down, because Mt. Gox keeps reserves in the nominal value equivalent to your deposit.<br />
<br />
<blockquote>As I've said, the money supply is currency in circulation plus demand deposits.</blockquote><br />
That's not what you said. Go back and read your own words. You also included bank reserves. In fact, you complained about me not including cash reserves in my definition of fiat FRB.<br />
<br />
<blockquote>If Satoshi moves a million Bitcoins from his wallet (which are 'in circulation') to a demand deposit, the money supply stays the same.</blockquote><br />
In that case, your prior definition of money supply is wrong and your whole argument collapses.<br />
<br />
<blockquote>The reason the last two columns are not equal is because you added bank reserves in your sum.</blockquote><br />
Go back and read what you wrote. You wrote several times that bank reserves are a part of the money supply. Look at the definition you quoted, and at the table you copied from the wikipedia article.<br />
<br />
You still have failed to address the question why are demand deposits a part of the money supply in the first place, whereas casino chips aren't (at least I hope you do not claim that casino chips are a part of the money supply).<br />

<br />
I just searched this thread for every occurrence of 'reserve' and read each paragraph and couldn't find where I claimed money supply includes bank reserves. Could you point it out for me?<br />
Concerning the table, I said that "Money Supply is M1". Note that M1 doesn't have a tick mark in the ''minimum reserves and excess reserves'' row.<br />
<br />
<blockquote>"According to your justification for demand deposits being a part of money supply (zero maturity claim), casino chips should also be a part of the money supply. Can you address this?" </blockquote><br />
<br />
If we are talking about the money supply of dollars, then casino chips, bitcoins, gold bars, and chickens are all not part of the money supply (of dollars). Only ''dollars'' are. If we are talking about casino chips, then casino chips are included in the money supply of casino chips but those other things are not. <br />
<br />
<br />
Is this statement correct? ''PeterSurda says that the Money Supply of Bitcoin is the total value of claims on Bitcoins which are an accepted method of payment.'' If that isn't correct, can you fix it?<br />
<br />
I would like to be able to calculate the money supply. Is this statement correct? ''PeterSurda says that Money Supply is the amount of money in circulation plus bank reserves.'' If that isn't correct, can you fix it? Thank You.<br />
<br />
<blockquote>"You own 100 bitcoins and a claim on 100 bitcoins. " </blockquote><br />
<br />
>99% of the population doesn't see it like that. They see the money in their bank account and money in their hand as basically the same thing. Certainly I admit that they aren't the same, but if you ask people how much money they have, nearly everyone is going to take the number of dollars (or euros, etc.) in their wallet and add the number of dollars (or euros) in their bank account, and tell you that number. They will also behave as if they have that number of dollars/euros. This is why demand deposits are included in the money supply. This is why my definition of money supply is useful. <br />
<br />
<blockquote>"So in your case the money supply is 200 BTC: 100 Bitcoins in your own wallet plus 100 Bitcoins as Mt.Gox reserves. The account balance you have with Mt.Gox does not appear in the equation. " </blockquote><br />

<blockquote>Not only did I say it, I said it three times!</blockquote><br />
I apologise, you used confusing terminology and I though that's what you're saying. Nevertheless, why did you pick M1 rather than M2 or MZM? You said that zero maturity is the reason why demand deposits are a part of the money supply.<br />
<br />
Let me address the two definitions you provide, monetary base and money supply.<br />
<br />
<b>Monetary base</b> is the money itself. In case of gold, it's the gold in existence. In case of fiat, it's very muddled: whatever the central bank produces (coins, banknotes, commercial bank deposits), to a certain extent other things, such as gold deposited in the CB, are also acceptable. In case of Bitcoin, it is Bitcoin. Claims on money are not a part of this.<br />
<br />
<b>Money supply</b> is all the base money, plus claims on money that people accept as a means of payment, minus reserves of the issuers of those claims.<br />
<br />
<blockquote>If we are talking about the money supply of dollars,</blockquote><br />
Casino chips (in US) are denominated in dollars, just like demand deposit accounts. Why are they not a part of the money supply, while demand deposits are?<br />
<br />
<blockquote>Is this statement correct?</blockquote><br />
No.<br />
<br />
<blockquote>If that isn't correct, can you fix it?</blockquote><br />
See above.<br />
<br />
<blockquote>I would like to be able to calculate the money supply.</blockquote><br />
See above.<br />
<br />
<blockquote>99% of the population doesn't see it like that.</blockquote><br />
There is a reason why economists use the definitions they use, and you still do not understand this reasoning. You use "money supply of dollars" when addessing casino chips, but what does it actually mean? Do you understand that?<br />
<br />
<blockquote>They see the money in their bank account and money in their hand as basically the same thing.</blockquote><br />
And the reason why they do this is that they can use it as a payment method instead of using cash printed by the central bank: e.g. cheque, EFT, debit card. That's also the reason why they do not see casino chips as money: they cannot use it as a payment method instead of the dollars (or euros or whatever). That's also the reason why economists include demand deposits in fiat world in the money supply. This reason is absent with Bitcoin, and there's little reason for it to change.<br />
<br />
See aforementioned Mises:<br />
<br />
<blockquote>Technically, and in some countries legally as well, the <b>transfer</b> of a banknote scarcely differs from that of a coin. The similarity of outward appearance is such that those who are engaged in commercial dealings are usually unable to distinguish between those objects that actually perform the function of money and those that are merely employed as substitutes for them. The businessman does not worry about the economic problems involved in this; he is only concerned with the commercial and legal characteristics of coins, notes, checks, and the like. To him, the facts that banknotes are <b>transferable</b> without documentary evidence, that they <b>circulate</b> like coins in round denominations, that no fight of recovery lies against their previous holders, that the law recognizes no difference between them and money as an <b>instrument of debt settlement</b>, seem good enough reason for including them within the definition of the term money, and for drawing a fundamental distinction between them and cash deposits, which can be <b>transferred</b> only by a procedure that is much more complex technically and is also regarded in law as of a different kind. <b>This is the origin of the popular conception of money by which everyday life is governed</b>. No doubt it serves the purposes of the bank official, and it may even be quite useful in the business world at large, but its introduction into the scientific terminology of economics is most undesirable.</blockquote><br />
<br />
In 1912 when he wrote it, he saw a difference between the cash deposit and a bank note. In the meantime, the difference has vanished, because it became much easier to do these transfers (e.g. cheque/debit card/EFT). With Bitcoin, you cannot transfer these balances among each other outside of closed systems, you need to perform a withdrawal as a part of the procedure.<br />
<br />
Once again, the reason why demand deposits are included in the supply of money is <b>not that they are redeemable on demand, but because they are an accepted method of payment</b>. That's the <b>purpose of the term money supply</b> too: to <b>measure the amount of whatever is usable for payment</b>. That is why casino chips and Surdas are not included in it, and that is why balances of claims-issuing companies like Mt.Gox and flexcoin should not be included in it either, as long as they are not used as a method of payment without conversion into "native" Bitcoin. That is also why economists use the definitions they use: the amount of things that are usable as payment is what they analyse, not the maturity of claims.<br />

One link to support my definition of money supply: http://wiki.mises.org/wiki/True_Money_Supply :<br />
<br />
<blockquote>Algebraically, TMS = Standard Money (held by the public) + Money Substitutes</blockquote><br />
<br />
And here is Rothbard in Austrian Definitions of the Supply of Money, http://mises.org/rothbard/austrianmoneysupply.pdf , confirming my analysis:<br />
<br />
<blockquote>It is important to recognize that demand deposits are not automatically part of the money supply by virtue of their very existence; they continue as equivalent to money <b>only so long as</b> the subjective estimates of the <b>sellers of goods</b> on the market think that they are so equivalent and <b>accept them as such in exchange</b>.</blockquote><br />

I picked M1 because that is what all the mainstream textbooks say. I believe they say that because the things in M1 are the things most people consider to be their ''money''. Certainly that definition of money isn't useful for all situations which is why those other M's are shown. This is why the word ''usually'' appears in the description of money supply on Wikipedia which you pointed out earlier.<br />
<br />
Concerning casino chips, I didn't know casino chips were valued in dollars. Now that I know that: Whether we consider casino chips part of the money supply or not has no effect on the size of the money supply; the money supply will remain the same. The reason is that supposing we consider casino chips to be money, then when we put 1 dollar into the casino's vault, that dollar is removed from the money supply, and one dollar in the form of a casino chip is added to the money supply. '''Notice that we are still talking about the money supply of dollars.''' (Chickens, Bitcoins, and Gold are not included.) The money supply remains equal to what is was earlier, but an additional dollar is now held in reserve. If you don't like this and don't want to say that casino chips are money; that's fine. In that case, the dollars in the vault are still part of the money supply and the chips simply represent a claim to retrieve them.<br />
<br />
<blockquote>"You use "money supply of dollars" when addressing casino chips, but what does it actually mean? Do you understand that?" </blockquote><br />
<br />
Did my above paragraph answer this? If no, can you please restate?<br />
<br />
<blockquote>"That's also the reason why they do not see casino chips as money: they cannot use it as a payment method instead of the dollars (or euros or whatever). " </blockquote><br />
<br />
Except that people ''do'' use casino chips as a payment method in cities like Las Vegas. You can pay a hooker or tip a waitress in a restaurant with the casino chips. If casinos were in every city, then you could use the casino chip anywhere as a payment method. Also, if you can't use a cash dollar as a method of payment in the jungle, wouldn't you have to admit that under your definition, tourists remove their dollars from the money supply when they visit the jungle?<br />
<br />
Concerning your quotes from Mises and Rothbard, and really your views at-large: This is the Austrian school of thought. This isn't mainstream. Your definition of money supply is not in textbooks taught in very many schools. Your definition of Fractional Reserve Banking thus doesn't match what most economists consider it to be.<br />

<br />
Regarding casino chips: I think we're making some progress. You argue that the reason why casino chips do not affect the money supply is not that they are not used as a general medium of exchange, but because the issuers thereof do not overissue them (FRB). How do you know they do not overissue?<br />
<br />
Use of chips as a payment method: please look at wikipedia page of Money: http://en.wikipedia.org/wiki/Money:<br />
<blockquote>Money is any object or record that is <b>generally accepted</b> as payment for goods and services and repayment of debts in a given country or socio-economic context.</blockquote><br />
(emphasis added) Are chips generally accepted? No, they are only accepted within a very narrow geographical area, and only for certain services. Similarly as vouchers, coupons, bus tickets and so on. So why do you think they should be reflected in the money supply? More importantly though, balances on Mt.Gox, flexcoin and so on are used as a medium of exchange even less: in the hypothetical scenario of transferring Bitcoins from Mt.Gox to flexcoin, rather than exchanging the balances, the Bitcoins are withdrawn from Mt.Gox, sent over the Bitcoin network, flexcoin stores them in their "reserve" wallet and issues new claims (balance) to the recipient. So even if we omitted the requirement for general acceptance, it still would not support your argument.<br />
<br />
As your example with jungle and uselessness of dollars, I admit that the definition is fuzzy, I have my own problems with it. But hopefully we can agree that unless you accept something as a means of payment, the change of supply of it has no effect on our spending decisions, correct? If Walmart issues vouchers in the value of, say, one trillion dollars, unless you intend to shop at Walmart, this has no effect on your purchasing decisions, correct?<br />
<br />
Most importantly though, you still haven't address the core issues. Why economists use the definitions they use? Why do the definitions of M1 say that it <b>usually</b> includes demand deposit, but not always? What does money supply measure? If you disagree with Austrians, what is your alternative explanation?<br />
<br />
While it isn't as clear from wikipedia as from the Rothbard quote, here it what it says about money supply: http://en.wikipedia.org/wiki/Money_supply :<br />
<blockquote>In economics, the money supply or money stock, is the total amount of money available in an economy at a specific time.</blockquote><br />
and<br />
<blockquote>Money is used as a medium of exchange, in final settlement of a debt, and as a ready store of value.</blockquote><br />
Are account balances on Mt. Gox or flexcoin used for any of this? Maybe for the last one. But they are rarely a medium of exchange or a final settlement of debt. The wikipedia article continues:<br />
<blockquote>Narrow measures include only the most liquid assets, the ones <b>most easily used to spend</b>...</blockquote><br />
(emphasis added) Are Mt.Gox / flexcoin balances used to spend? In general, no, they are redeemed into Bitcoins in order to spend them.<br />
<br />
Mt.Gox offers the following methods of transferring Bitcoins:<br />
<br />
* redeemable Mt.Gox code<br />
* Green address<br />
* Bitcoin address<br />
<br />
Only the first one is a claim, the others are native Bitcoin. The claim is only usable for other Mt.Gox users.<br />
<br />
Flexcoin offers the following methods of transferring Bitcoins:<br />
<br />
* another flexcoin ID<br />
* an e-mail address<br />
* an external bitcoin address<br />
<br />
The first two are claims (I think, I am not sure about the inner workings of flexcoin). The claim is only usable for other flexcoin users.<br />
<br />
The only people who are affected by (hypothetically) inflated balances of Mt. Gox or flexcoin are those that accept those claims. From this perspective, both functionally and scope-wise, this is similar to the aforementioned casino chips, vouchers and so on. It does not have an effect on the money supply any more than an overissue of casino chips has effect on the purchasing decisions of people other than the casino guests, aforementioned hookers and waiters.<br />

I assumed that casinos weren't over issuing chips. I've just done some research and found that they are allowed to do this legally. So they are probably doing it. So they are increasing the money supply of dollars.<br />
<br />
We could argue all day about what things are 'generally accepted'. 100 bills aren't generally accepted at gas stations. We shouldn't read too much into that particular phrase. Casino chips wouldn't be ''money'' far away from a casino, but they are money in Las Vegas. I have a Chinese 2 unit bill around here somewhere. It isn't money to me.<br />
<br />
<blockquote>"If Walmart issues vouchers in the value of, say, one trillion dollars, unless you intend to shop at Walmart, this has no effect on your purchasing decisions, correct? "</blockquote><br />
<br />
If everyone in a 'community' of some sort shops at Walmart, then the vouchers would start to be traded like money among the members of the community for goods and services for a period of time before making their way back to Walmart.<br />
<br />
<blockquote>"Why economists use the definitions they use?"</blockquote><br />
<br />
Because their definitions are the most useful. <br />
<br />
<blockquote>"Why do the definitions of M1 say that it usually includes demand deposit, but not always?"</blockquote><br />
<br />
You are confused. The definition of M1 always includes demand deposits. The definition of money is usually M1. The definition of money is usually M1 because in most situations when you ask someone how much money they have, they add up the things in M1. <br />
<br />
<blockquote>"What does money supply measure?"</blockquote><br />
<br />
I've answered this six times.<br />
<br />
<blockquote>"If you disagree with Austrians, what is your alternative explanation? "</blockquote><br />

Here is [http://en.wikipedia.org/wiki/Money_supply Money supply].<br />
<br />
<blockquote>"Narrow measures include only the most liquid assets, the ones most easily used to spend... "</blockquote><br />
<br />
So are you telling me that money stops being money when you put it in a bank, or MtGox? Because you are telling me that money in MtGox isn't sufficiently easy to spend because their transfers naturally aren't accepted by everyone.<br />
<br />
<blockquote>"It does not have an effect on the money supply any more than an overissue of casino chips has effect on the purchasing decisions of people other than the casino guests, aforementioned hookers and waiters. "</blockquote><br />
<br />
No no; because the money supply increases as I described above, the value of each dollar goes down slightly which affects everyone.<br />
<br />
I would like you to respond to this example:<br />
<br />
Suppose that there are only 100 Bitcoins on Earth all owned by Satoshi. He puts all 100 in Bank Alpha. Bank Alpha puts 20 of the bitcoins (20%) in a special account and leaves them there. They then lend out 80 bitcoins to Gavin. Bank Alpha tells Satoshi on his account page that his account has 100 bitcoins in it. Now, Gavin buys some LolCat comics from Cameron for 80 bitcoins. Cameron puts his 80 bitcoins in his bank, Bank Beta. Bank Beta puts 20% in reserve (16 bitcoins) and has 64 to lend out. They lend those 64 bitcoins to someone else. Cameron's account page on Bank Beta's website says he has 80 bitcoins in his account. Despite the fact that Satoshi, Gavin, and Cameron only have claims to bitcoins, isn't the fact that they collectively know they can access 244 bitcoins significant to note and measure? This means that each bitcoin will be nearly 1/3rd as valuable as before Fractional Reserve Banking. How is that not significant?<br />

Here we have it from wikipedia ( http://en.wikipedia.org/wiki/Demand_deposit : )<br />
<blockquote>Demand deposits are usually considered part of the money supply, <b>as they can be used, via checks and drafts, as a means of payment</b> for goods and services and to settle debts.</blockquote><br />
(emphasis added)<br />
<br />
Another link: http://www.economicsjunkie.com/true-money-supply/ :<br />
<blockquote>Virtually everyone accepts payment in demand deposit money. Demand deposits are thus to be included in the money supply.</blockquote><br />
<br />
And here we have the Federal Reserve Bank of New York, http://www.ny.frb.org/aboutthefed/fedpoint/fed49.html :<br />
<blockquote>The money supply measures reflect the different degrees of liquidity—or <b>spendability</b>—that different types of money<br />
have.</blockquote><br />
<br />
So what reason do you have in asserting that maturity, rather than acceptability in transactions (as seen above), is the reason for including a claim in the money supply? And what do you think money supply actually<br />
measures?<br />

<blockquote>So are you telling me that money stops being money when you put it in a bank, or MtGox?</blockquote><br />
It stops being a part of the money supply if it is held as reserve for money substitutes.<br />
<br />
<blockquote>Because you are telling me that money in MtGox isn't sufficiently easy to spend because their transfers naturally aren't accepted by everyone.</blockquote><br />
What this means is that these balances are not money substitutes, only claims. They are not a part of the money supply of Bitcoin, rather the "reserves" of Mt.Gox are, because these "reserves" are what circulates if people are transferring Bitcoin among themselves. It is the equivalent of gold being able to instantly teleport among vaults at negligible cost. If this was possible, bank notes, cheques and EFT would not be used for exchange of gold, and bank balances would cease to be a part of the money supply.<br />

Another definition: http://www.investorwords.com/3110/money_supply.html :<br />
<br />
<blockquote>The total supply of money <b>in circulation</b> in a given country's economy at a given time.</blockquote><br />
<br />
These quotes (and the ones from previous post) lead to the following conclusion:<br />
<br />
* the money supply does not measure the nominal value of zero maturity instruments denominated in that currency, but the nominal value of the instruments that are accepted as media of exchange<br />
* deposit accounts are not always, by their virtue, a part of the money supply, but only to the extent they are accepted as a method of exchange<br />

I've cited many sources throughout this thread. I can even take your own Fed link and see that "The Federal Reserve publishes weekly and monthly data on two money supply measures M1 and M2. ... The narrowest measure, M1, is restricted to the most liquid forms of money; it consists of currency in the hands of the public; travelers checks; demand deposits, and other deposits against which checks can be written. M2 includes M1, plus savings accounts, time deposits of under $100,000, and balances in retail money market mutual funds."<br />

Despite the fact that Satoshi, Gavin, and Cameron only have claims to bitcoins, isn't the fact that they collectively know they can access 244 bitcoins significant to note and measure? This means that each bitcoin will be nearly 1/3rd as valuable as before Fractional Reserve Banking. How is that not significant?<br />
<br />
'''--------PeterSurda Response-------'''<br />
<br />
Atheros, your quotes do not address my points at all, they skip over them. From this you incorrectly conclude that they disagree with my arguments.<br />
<br />
In your example, since Gavin, Cameron and Satoshi cannot at the same time buy anything worth more than 100 Bitcoins without using their account balances as a medium of exchange (thus elevating it into a status of money substitute), it means the money supply is only 100 Bitcoins. That's the purpose of the term money supply, it measures how much can be spent.<br />
<br />
Your is the definition that is not useful in economic theories. Money supply measures the amount that is available for payment. Not the sum of zero-maturity debt instruments. Absent the requirement to be usable as a medium of exchange, it cannot be used in calculations of inflation or money velocity. You practically invented your own economic theory.<br />
<br />
I challenge you to pick any professional economists, who disagrees with either of these claims:<br />
* The purpose of the money supply is to measure the nominal value of whatever is used as a medium of exchange.<br />
* The reason why demand deposits are included in the money supply is because they are used as a generally accepted medium of exchange.<br />

= Bitcoin mining is a waste of energy and harmful for ecology =<br />

IMHO this chapter is superficial. Compare Bitcoin to electronic fiat currencies. --[[User:Shrewdwatson|Shrewdwatson]] 17:57, 23 April 2011 (GMT)<br />
<br />
<br />
How about this:<br />
<br />
''The electricity spent in hashing is not wasted. It creates a product of value to the Bitcoin economy. The product is a supersignature on the complete list of transactions to date (the [[Block chain]]). This supersignature attesting to the chain's completeness is Bitcoin's defense against double spending.''<br />
<br />
''Many sources of energy vary in their availability in ways that do not match the variations in demand. The law of supply and demand will require Bitcoin to soak up a lot of energy that is currently "wasted" without making a big dent in the otherwise usable energy supply. [Perhaps cite estimates of the break-even point for mining profitability that imply near zero-cost electricity.]''<br />

I'd like to comment on the fact that new bitcoins are evenly and competitively distributed over a period of 140 years or so. We are still very much in the "early" stages of bitcoin and only just recently passed "the half way mark" with two more halvings in the next 8 years. The generation of 90% of all new bitcoins happens over the first 15 years or so.

<br />
=== Finding a direct seller ===<br />
If you can find another person that is willing to sell them to you, you can transfer him money via whatever method (including Paypal), and he'll send you the Bitcoins. One place to look for people willing to sell is [[Bitcoin OTC]].<br />

<br />
[http://ecdsa.org/electrum Electrum] is a lightweight Bitcoin client, based on a client-server protocol. <br />
It was released on november 5, 2011.<br />
<br />
'''Main features:'''<br />
* Encrypted wallet: the file that contains your bitcoins is protected with a password. You are protected from thieves.<br />
* Deterministic key generation: If you lose your wallet, you can recover it from its seed. You are protected from your own mistakes.<br />
* Instant on: the client does not download the blockchain, it requests that information from a server. No delays, always up-to-date.<br />
* Transactions are signed locally: Your private keys are not shared with the server. You do not have to trust the server with your money.<br />
* Freedom and Privacy: The server does not store user accounts. You are not tied to a particular server, and the server does not need to know you.<br />
* No scripts: Electrum does not download any script. A compromised server cannot send you arbitrary code and steal your bitcoins.<br />
* No single point of failure: The server code is open source, anyone can run a server.<br />
* Firewall friendly: The client does not need to open a port, it simply polls the server for updates.<br />
* Free software: Gnu GPL v3. Anyone can audit the code.<br />
* Written in Python. The code is short, and easy to review.<br />
* Support for Bitcoin URIs, signed URIs and Bitcoin aliases<br />
<br />
<br />
__TOC__<br />
<br />
===Graphical User Interfaces===<br />
Electrum has two GUIs: one that is based on Gtk, and a newer one based on Qt. The Qt GUI is enabled by default. To use the gtk interface, type:<br />
<pre><br />
$ ./electrum -g gtk<br />
</pre><br />
In addition, Electrum has a rich set of commands for the command line interface.<br />
<br />
===Brain Wallet===<br />
<br />
Electrum uses a type 2 deterministic key generation algorithm.<br />
This means that all the keys are derived from a seed.<br />
<br />
Typical seeds have 128 bits of entropy. Electrum provides mnemonic code in order to represent the seed.<br />
<br />
Example:<br />
*hexadecimal: 431a62f1c86555d3c45e5c4d9e10c8c7 <br />
*mnemonic: "constant forest adore false green weave stop guy fur freeze giggle clock"<br />
<br />
You can display the seed with the command line interface. Example:<br />
<pre><br />
$ ./electrum seed<br />
Password:<br />
431a62f1c86555d3c45e5c4d9e10c8c7 "constant forest adore false green weave stop guy fur freeze giggle clock"<br />
</pre><br />
<br />
===Multiple wallets===<br />
Electrum uses one single file per wallet. Your default wallet is located in your user account.<br />
If you want to use another wallet, use the -w option followed by the wallet path and name:<br />
<pre><br />
$ ./electrum -w /path/to/my/wallet/wallet_name<br />
</pre><br />
<br />
===Export and import addresses===<br />
<br />
You can export your private keys using the 'addresses' command:<br />
<pre><br />
$ ./electrum addresses -ak<br />
Password:<br />

</pre><br />
There are two options in this example:<br />
* option -a means: 'list all addresses'. if you don't use it, change addresses are not listed.<br />
* option -k means: display the private keys<br />
<br />
You can also import addresses into an electrum wallet, with the 'import' command:<br />
<pre><br />
$ ./electrum import 1LGoehbyeX4QBEPK1a6dhyaoMQZfqg5LKX:5JBSttEGhjEcPidSovW66Rin2EZ6LEHZ2qx8Pu2RqqNaDTBVWaF<br />
keypair imported<br />
</pre><br />
Note that imported keys do not belong to the deterministic sequence of your wallet; if you import keys in a wallet, you must back it up!<br />
<br />
===Offline wallet===<br />
<br />
It is possible to create a transaction on an offline computer,<br />
and to broadcast them from another computer, with a wallet that does not have the seed or private keys.<br />
<br />
====How to prepare an offline wallet ====<br />
*step 1: create a wallet on your offline computer<br />
<pre><br />
[offline]$ electrum -o -w wallet create<br />
</pre><br />
*step 2: extract the seed from your wallet file:<br />
<pre><br />
[offline]$ electrum -o -w wallet deseed <br />
</pre><br />
This will remove the seed from 'wallet', and save it to a file named 'wallet.seed'<br />
*step 3: transfer the deseeded wallet to the online computer (for example with a usb stick)<br />
*step 4: run electrum on the online computer; this will synchronize your wallet with the bitcoin network, and you will be able to monitor incoming transactions:<br />
<pre><br />
[online]$ electrum -w wallet<br />
</pre><br />
<br />
====How to send a transaction with an offline wallet====<br />
*step 1: copy the synchronized wallet file to your offline computer, in the directory where the seed is.<br />
*step 2: restore the seed in the wallet file:<br />
<pre><br />
[offline]$ electrum -w wallet reseed<br />
</pre><br />
*step 3: create the transaction<br />
<pre><br />
[offline]$ electrum -w wallet mktx <recipient> <amount> > tx_file<br />
</pre><br />
*step 4: with the usb stick, copy the transaction to the online computer:<br />
*step 5: broadcast the transaction on the online computer:<br />
<pre><br />
[online]$ electrum -w wallet sendtx `cat tx_file`<br />
</pre><br />

<hr />
<div>Any reason the 'bitcoin first' page is separate from the older History page?<br />
<br />
Ya, probably so that the History page was more specific to bitcoin, but firsts was for trivia and only true firsts.<br />
<br />
Like maybe going to v0.6 release is enough to make it into the History, but not something that would go into firsts.<br />
At the same time, the first food truck to start using bitcoin might be something suitable for the Firsts page but would be extraneous in the Bitcoin History page.<br />
<br />

* [http://www.youtube.com/watch?v=soGrVGlC9gw First Amateur Adult Entertainer posts a HOWTO use Bitcoin video] 2012-03-28</div>JulianToshhttps://en.bitcoin.it/w/index.php?title=Fallback_Nodes&diff=24519Fallback Nodes2012-03-07T18:10:25Z<p>JulianTosh: /* Tor nodes */</p>
<hr />
<div>This is a list of nodes which are considered reliable. Nodes from this list which are down for more than 24 hours will be automatically removed and status of each node is displayed and updated every hour by [[User:WikiBot|WikiBot]].<br />
<br />
== How to use this list ==<br />
<br />
=== Connect to nodes ===<br />
<br />
You can connect to these nodes with the ''-addnode=ip'' switch instead of the usual node harvesting process (through IRC or via the embedded nodelist). You can connect to more than one node by using ''-addnode=ip'' more than once. It is usually a good idea to connect to more than one of these nodes.<br />
<br />
==== Nodes without a fixed ip ====<br />
<br />
If the node IP is not fixed (see "Fixed" column), you will have to resolve the node's name (first column) each time the IP changes. Some nodes may have their ip change once a day, some others once a month, and some others may stay on the same IP for years. Still, as long as the IP is not fixed, there is no guarantee it will stay the same.<br />
<br />
In order to enable hostname lookups for the ''-addnode'' and ''-connect'' parameters, you must additionally provide the ''-dns'' parameter. Example:<br />
bitcoind -dns -addnode=bitcoin.es<br />
<br />
Versions prior to 0.3.22 do not support hostnames to the ''-addnode'' parameter, so you must do the resolving part for it. For example on linux:<br />
bitcoind -addnode=$(dig +short bitcoin.es)<br />
<br />
=== IP Transactions ===<br />
<br />
You can also send [[IP Transactions]] to these nodes. If you include your bitcoin address in the "message" field, you may have your coins back.<br />
<br />
=== Tor network ===<br />
<br />
To use tor .onion addresses ([[Fallback_Nodes#Tor_nodes|listed below]]), you will need to map virtual ips via the ''torrc'' file:<br />
<br />
mapaddress 192.0.2.2 ijzt2eeizty3p5xe.onion<br />
mapaddress 192.0.2.3 j43z65b6r2usg3vk.onion<br />
mapaddress 192.0.2.4 pvuif6nonbhj3o3r.onion<br />
<br />
And then put these IPs in your bitcoin.conf (or run bitcoin with -connect)<br />
<br />
connect=192.0.2.2<br />
connect=192.0.2.3<br />
connect=192.0.2.4<br />
<br />
You can use any arbitrary IP addresses with MapAddress, though some of the common non-routable ranges (10.*, 192.168.*) will not work due to a Bitcoin bug (reference?). 192.0.2.1-192.0.2.255 is the recommended range because it is both non-routable and compatible with Bitcoin.<br />
<br />
It is highly recommended that you use "connect" instead of "addnode" so that all of your communications are kept within the tor network.<br />
<br />
<span style="color:red">Since Bitcoin 0.5, the client enables nolisten when the proxy setting is enabled, which in effect prevents the client from becoming a peer node. So the only way to operate a hidden bitcoin seed node would be to revert to an earlier version, or see phantomcircuit's [https://github.com/phantomcircuit/bitcoin-alt bitcoin-alt].</span><br />

== Adding a node ==<br />
<br />
Before adding yourself as a fallback node, you should be sure your node will stay online for a long time. If a node is offline for more than 24 hours it will be removed from the list. To accept IP transactions you will have to add the ''-allowreceivebyip'' flag to your command line parameters.<br />
<br />
To add a node in this list, you just need the ip/hostname and your name, the other fields will be filled automatically. Insert the following lines before the <tt>END NODELIST</tt> line:<br />
<br />
<nowiki>|-<br />
| ip || your name</nowiki><br />
<br />
Please note that a bot is supposed to connect to your node every hour to check its status and version. Sadly, this bot appears to be offline.</div>JulianToshhttps://en.bitcoin.it/w/index.php?title=Fallback_Nodes&diff=24518Fallback Nodes2012-03-07T17:06:21Z<p>JulianTosh: </p>
<hr />
<div>This is a list of nodes which are considered reliable. Nodes from this list which are down for more than 24 hours will be automatically removed and status of each node is displayed and updated every hour by [[User:WikiBot|WikiBot]].<br />
<br />
== How to use this list ==<br />
<br />
=== Connect to nodes ===<br />
<br />
You can connect to these nodes with the ''-addnode=ip'' switch instead of the usual node harvesting process (through IRC or via the embedded nodelist). You can connect to more than one node by using ''-addnode=ip'' more than once. It is usually a good idea to connect to more than one of these nodes.<br />
<br />
==== Nodes without a fixed ip ====<br />
<br />
If the node IP is not fixed (see "Fixed" column), you will have to resolve the node's name (first column) each time the IP changes. Some nodes may have their ip change once a day, some others once a month, and some others may stay on the same IP for years. Still, as long as the IP is not fixed, there is no guarantee it will stay the same.<br />
<br />
In order to enable hostname lookups for the ''-addnode'' and ''-connect'' parameters, you must additionally provide the ''-dns'' parameter. Example:<br />
bitcoind -dns -addnode=bitcoin.es<br />
<br />
Versions prior to 0.3.22 do not support hostnames to the ''-addnode'' parameter, so you must do the resolving part for it. For example on linux:<br />
bitcoind -addnode=$(dig +short bitcoin.es)<br />
<br />
=== IP Transactions ===<br />
<br />
You can also send [[IP Transactions]] to these nodes. If you include your bitcoin address in the "message" field, you may have your coins back.<br />
<br />
=== Tor network ===<br />
<br />
To use tor .onion addresses ([[Fallback_Nodes#Tor_nodes|listed below]]), you will need to map virtual ips via the ''torrc'' file:<br />
<br />
mapaddress 192.0.2.2 ijzt2eeizty3p5xe.onion<br />
mapaddress 192.0.2.3 j43z65b6r2usg3vk.onion<br />
mapaddress 192.0.2.4 pvuif6nonbhj3o3r.onion<br />
<br />
And then put these IPs in your bitcoin.conf (or run bitcoin with -connect)<br />
<br />
connect=192.0.2.2<br />
connect=192.0.2.3<br />
connect=192.0.2.4<br />
<br />
You can use any arbitrary IP addresses with MapAddress, though some of the common non-routable ranges (10.*, 192.168.*) will not work due to a Bitcoin bug (reference?). 192.0.2.1-192.0.2.255 is the recommended range because it is both non-routable and compatible with Bitcoin.<br />
<br />
It is highly recommended that you use "connect" instead of "addnode" so that all of your communications are kept within the tor network.<br />
<br />
<span style="color:red">Since Bitcoin 0.5, the client enables nolisten when the proxy setting is enabled, which in effect prevents the client from becoming a peer node. So the only way to operate a hidden bitcoin seed node would be to revert to an earlier version, or see phantomcircuit's [https://github.com/phantomcircuit/bitcoin-alt bitcoin-alt].</span><br />

<hr />
<div>The purpose of this page is to provide a general overview of the Bitcoin system and economy.<br />
<br />
==Basic Concepts==<br />
<br />
===Currency===<br />
<br />
Alice is far away from Bob and wants to buy his [http://www.grasshillalpacas.com/alpacaproductsforbitcoinoffer.html Alpaca socks]. In return, she wants to send him a dollar. A dollar bill is a piece of paper which is very easy to create (by those who can), but which is accepted by people in exchange for valuable products and services in the real world, such as the socks Alice wants to buy. One simple thing Alice can do is put a dollar bill in an envelope, mail it to Bob, and then wait for Bob to send the socks to her.<br />
<br />
===Banks===<br />
<br />
Another thing Alice can do is to "wire" the money to Bob. She can do that by first giving her dollar bills to an institution called a bank, the job of which is to safe-keep Alice's dollar bills and, in return, to give Alice a written promise (called a "bank statement") that, whenever she wishes, she can come to the bank to take back the same number of dollar bills that she deposited. Since the money is still Alice's, she is entitled to do with it whatever she pleases, and the bank (like most banks), for a small fee, will do Alice the service of "giving" the dollar bills to Bob instead of her. This could be done by sending a person to Bob's door, with Alice's dollar bills in hand (or, better, fresh new dollar bills, if Alice's dollar bills are in bad condition), but usually it is done by Alice's bank by giving the dollar bills to Bob's bank and informing them that the money is for Bob, who will then see the amount in his next statement, or, if he is in a hurry, the next time he contacts his bank asking about how much money they have for him.<br />
<br />
Since banks have many customers, and bank employees require money for doing the job of talking to people and signing documents, banks in recent times have been using machines such as ATMs and web servers, that do the job of interacting with customers instead of paid bank employees. The job of these machines is to learn what each customer wants to do with his/her money and, to the extent that it's possible, act on what the customer wants (for example, ATMs can hand cash). In the end, there is very little human involvement in this process, most of the time. The people can always know how much money out of the money that the bank is safe-keeping is theirs, and they are confident that the numbers they see in their bank statements and on their computer screens stand for the number of dollar bills that they can get from the bank at any time they wish. They can be so sure of that, that they can accept those numbers in the same way they accept paper dollars (this is similar to the way people started accepting paper dollars as they accepted gold or silver).<br />
<br />
However, the fact that machines are used does not change the structure of this system, which is, as it was, based on a central authority (the bank) which is responsible for keeping records about how much money belongs to whom. Everybody has to rely on this central authority to be honest (i.e. to say the truth about how much money they are safe-keeping in total, or at least to make the paper money available upon demand from the owners). Also, every person has to identify him/herself to this authority, by giving his/her real name, in order to be allowed to get their paper bills back or to send money to another person.<br />
<br />
Bitcoin is a system of owning and voluntarily transferring amounts of so-called bitcoins, in a manner similar to an on-line banking interface, but anonymously and without reliance on a central authority to maintain account balances. These bitcoins are valuable because they are useful and because they are limited in supply.<br />
<br />
==Bitcoin Basics==<br />
<br />
===Creation of coins===<br />
The creation of coins must be limited for the currency to have any value. <br />
<br />
New coins are slowly "mined" into existence by following a mutually agreed-upon set of rules. A user "mining" bitcoins is running a program that searches tirelessly for a solution to a very difficult math problem whose difficulty is precisely known. The difficulty is automatically adjusted regularly so that the number of solutions found globally, by everyone, is constant: an average of 6 per hour. When a solution is found, the user may tell everyone of the existence of this new found solution, along with other information, packaged together in what is called a "block". <br />
<br />
Blocks contain 50 bitcoins at present. This amount is an incentive for people to perform the computation work required for block generation. Roughly every 4 years, the number of bitcoins that can be "mined" in a block reduces by 50%. Any blocks that are created by a malicious user that do not follow this rule (or any other rules) will be rejected by everyone else. The result is that no more than 21 million bitcoins will ever exist. <br />
<br />
Because the "mining" incentive to put fourth the computational power to create blocks will eventually diminish, miners will some day pay for their hardware and electricity costs by collecting [[Transaction_fee|transaction fees]]. The sender of money may voluntarily pay a small transaction fee which will be kept by whoever finds the next block. Paying this fee will encourage the miner to include the transaction in a block more quickly.<br />
<br />
===Transferring a coin===<br />
To guarantee that an eavesdropper, Eve, cannot access other people's bitcoins by creating transactions in their names we use a [[Wikipedia:Public-key_cryptography|public key system]] to make digital signatures. In this system, each person, such as Alice and Bob, has a pair of public and private keys which he/she stores in a safe [[Wallet|wallet]]. Only the user with his secret private key can sign a document, such as the transaction to give some of his bitcoins to somebody else, but any one can validate the signature using the user’s public key.<br />
<br />
Suppose Alice wants to send a bitcoin to Bob.<br />
* Bob sends his public key to Alice.<br />
* Alice adds Bob’s public key along with the amount she wants to transfer to a message: a 'transaction' message.<br />
* Alice signs the transaction with her secret private key.<br />
* Alice broadcasts the transaction out over the bitcoin network for all to see.<br />
<br />
(Only the first step is actually completed by a human. The rest is done by the bitcoin client software.)<br />
<br />
As a result, anyone who knows the public keys of both Alice and Bob can now see that Alice agreed to transfer the amount to Bob, because nobody other than Alice has Alice's private key. Alice would be foolish to give her private key to other people, as this would allow them to sign transactions in her name, removing funds from her control.<br />
<br />
Later on, when Bob wishes to transfer the same bitcoin to Charley, he will do the same thing:<br />
* Charlie sends Bob his public key.<br />
* Bob adds Charlie's public key along with the amount he wants to transfer to a message: a 'transaction' message.<br />
* Bob signs the transaction with his private key.<br />
* Bob broadcasts the transaction out over the bitcoin network for all to see. <br />
<br />
Only Bob can do this because only Bob has the private key that corresponds to the public key Alice included in the previous transaction. <br />
<br />
Eve cannot change who the coins belong to by replacing Bob’s public key with her public key, because Alice signed the transfer to Bob using her private key, declaring that the coins which belonged to her now belong to Bob, and Alice's private key is kept secret from Eve. So if Charley accepts that the original coin was in the hands of Alice he will also accept the fact that this coin was later passed to Bob and now Bob is passing this same coin to him.<br />
<br />
===Preventing double-spending===<br />
The process described above does not prevent Alice from using a coin in more than one transaction. The following process does. This is the primary innovation behind Bitcoin.<br />
<br />
* Details about the [[Transactions|transaction]] are [[Network|sent and forwarded]] to all or as many other computers as possible.<br />
* A constantly growing chain of [[Blocks|blocks]] that contains a record of all transactions is collectively maintained by all computers (each has a full copy).<br />
* To be accepted in the chain, transaction blocks must be valid and must include [[proof of work]] (one block generated by the network every 10 minutes).<br />
* Blocks are chained in a way so that, if any one is modified, all following blocks will have to be recomputed.<br />
* When multiple valid continuations to this chain appear, only the longest such branch is accepted and it is then extended further.<br />
<br />
When Bob sees that his transaction has been included in a block, which has been made part of the single longest and fastest-growing block chain (extended with significant computational effort), he can be confident that the transaction by Alice has been accepted by the computers in the network and is permanently recorded, preventing Alice from creating a second transaction with the same coin. In order for Alice to thwart this system and double-spend her coins, she would need to muster more computing power than all other bitcoin users combined.<br />
<br />
===Anonymity===<br />
There are no bitcoin "accounts" to set up, no e-mail addresses and no user-names and passwords to give, just for owning bitcoins. Each balance is simply associated with a randomly generated public-private key pair and the money "belongs" to whoever has the private key and can sign transactions with it. Moreover, those keys do not have to be registered anywhere in advance, as they are only actually used if and when there is a transaction involving them. Transacting parties do not need to know each other's identity in the same way that a store owner does not know Bob's name is Bob when Bob goes and buys groceries with cash.<br />
<br />
A [[Address|Bitcoin address]] mathematically corresponds to a public key and looks like this:<br />
<br />
:15VjRaDX9zpbA8LVnbrCAFzrVzN7ixHNsC<br />
<br />
Each person can have many such addresses, each with its own balance, which makes it very difficult to know which person owns what amount. In order to protect his [[Anonymity|privacy]], Bob can even generate a new public-private key pair for each individual transaction. The Bitcoin software encourages this behavior by default. Continuing the example from above, when Charlie receives the bitcoin from Bob, Charlie will not be able to identify who owned the coin before Bob (not without asking Bob).<br />
<br />
You have completed reading our Bitcoin introduction!<br />
<br />
==Where to see and explore==<br />
You can directly explore the system in action by visiting the [http://blockexplorer.com/ Bitcoin Block Explorer].<br />
The site shows you the latest blocks in the block chain. The [[Block_chain|block chain]] contains the agreed history of all transactions that took place in the system.<br />
Note how many blocks were generated in the last hour which on average will be 6. Also notice the number of transactions and the total amount transferred in the last hour (last time I checked it was about 64 and 15K).<br />
This should give you an indication of how active the system is.<br />
<br />
Next, drill into one of these blocks.<br />
Start by noticing that the block's [[hash|hash]] begins with a run of zeros. This what made making it so difficult; a hash that begins with many zeros is much more difficult to find than a hash with few or no zeros. The computer that generated this block had to try many ''Nonce'' values (also listed on the block's page) until it found one that generated this run of zeros.<br />
Next notice the line titled ''Previous block'', each block contains the hash of the block that came before it, this is what forms the chain of blocks.<br />
Now notice all the transactions the block contains. The first transaction is the income earned by the computer that generated this block. It includes a fixed amount of coins created out of thin air and possibly fee collected from other transactions in the same block.<br />
<br />
Drill into any of the transactions and you will see how it is made from one or more amounts coming in and out.<br />
The fact that there can be more than one incoming and outgoing amounts, allow the system to join and break amounts in any possible way allowing for any fractional amount needed. Each incoming amount is a transaction from the past (which you can also drill to) coming from an address of someone and each outgoing amount is addressed to someone and will be part of a future transaction (which you can also drill too if it also had already taken place.)<br />
<br />
Finally you can drill into any of the [[Address|addresses]] and see what public information is available.<br />
<br />
To get an impression of the amount of activity on the Bitcoin network, you might like to visit the monitoring websites [[Bitcoin Monitor]] and [[Bitcoin Watch]]. The first shows a real-time visualization of events on the Bitcoin network and the second lists general statistics on the amount and size of recent transactions.<br />
<br />
===How many people use Bitcoin?===<br />
<br />
This is quite a difficult question to answer accurately. The best estimation is to count how many bitcoin clients connected to the network in the last 24 hours. We can do this as the client transmits its address to the other members of the network periodically. The estimate as of Sept 2011 is about 60,000 users. To get a more current estimate see [http://bitcoinstatus.rowit.co.uk/ Bitcoin Network Status Charts]<br />

The people can always know how much money out of the money that the bank is safe-keeping is theirs, and they are confident that the numbers they see in their bank statements and on their computer screens stand for the number of dollar bills that they can get from the bank at any time they wish. They can be so sure of that, that they can accept those numbers in the same way they accept paper dollars (this is similar to the way people started accepting paper dollars as they accepted gold or silver).<br />
<br />
However, the fact that machines are used does not change the structure of this system, which is, as it was, based on a central authority (the bank) which is responsible for keeping records about how much money belongs to whom. Everybody has to rely on this central authority to be honest (i.e. to say the truth about how much money they are safe-keeping in total, or at least to make the paper money available upon demand from the owners). Also, every person has to identify him/herself to this authority, by giving his/her real name, in order to be allowed to get their paper bills back or to send money to another person.<br />
<br />
Bitcoin is a system of owning and voluntarily transferring amounts of so-called bitcoins, in a manner similar to an on-line banking interface, but anonymously and without reliance on a central authority to maintain account balances. These bitcoins are valuable because they are useful and because they are limited in supply.<br />
<br />
==Bitcoin Basics==<br />
<br />
===Creation of coins===<br />
The creation of coins must be limited for the currency to have any value. <br />
<br />
New coins are slowly "mined" into existence by following a mutually agreed-upon set of rules. A user "mining" bitcoins is running a program that searches tirelessly for a solution to a very difficult math problem whose difficulty is precisely known. The difficulty is automatically adjusted regularly so that the number of solutions found globally, by everyone, is constant: an average of 6 per hour. When a solution is found, the user may tell everyone of the existence of this new found solution, along with other information, packaged together in what is called a "block". <br />
<br />
Blocks contain 50 bitcoins at present. This amount is an incentive for people to perform the computation work required for block generation. Roughly every 4 years, the number of bitcoins that can be "mined" in a block reduces by 50%. Any blocks that are created by a malicious user that do not follow this rule (or any other rules) will be rejected by everyone else. The result is that no more than 21 million bitcoins will ever exist. <br />
<br />
Because the "mining" incentive to put fourth the computational power to create blocks will eventually diminish, miners will some day pay for their hardware and electricity costs by collecting [[Transaction_fee|transaction fees]]. The sender of money may voluntarily pay a small transaction fee which will be kept by whoever finds the next block. Paying this fee will encourage the miner to include the transaction in a block more quickly.<br />
<br />
===Transferring a coin===<br />
To guarantee that an eavesdropper, Eve, cannot access other people's bitcoins by creating transactions in their names we use a [[Wikipedia:Public-key_cryptography|public key system]] to make digital signatures. In this system, each person, such as Alice and Bob, has a pair of public and private keys which he/she stores in a safe [[Wallet|wallet]]. Only the user with his secret private key can sign a document, such as the transaction to give some of his bitcoins to somebody else, but any one can validate the signature using the user’s public key.<br />
<br />
Suppose Alice wants to send a bitcoin to Bob.<br />
* Bob sends his public key to Alice.<br />
* Alice adds Bob’s public key along with the amount she wants to transfer to a message: a 'transaction' message.<br />
* Alice signs the transaction with her secret private key.<br />
* Alice broadcasts the transaction out over the bitcoin network for all to see.<br />
<br />
(Only the first step is actually completed by a human. The rest is done by the bitcoin client software.)<br />
<br />
As a result, anyone who knows the public keys of both Alice and Bob can now see that Alice agreed to transfer the amount to Bob, because nobody other than Alice has Alice's private key. Alice would be foolish to give her private key to other people, as this would allow them to sign transactions in her name, removing funds from her control.<br />
<br />
Later on, when Bob wishes to transfer the same bitcoin to Charley, he will do the same thing:<br />
* Charlie sends Bob his public key.<br />
* Bob adds Charlie's public key along with the amount he wants to transfer to a message: a 'transaction' message.<br />
* Bob signs the transaction with his private key.<br />
* Bob broadcasts the transaction out over the bitcoin network for all to see. <br />
<br />
Only Bob can do this because only Bob has the private key that corresponds to the public key Alice included in the previous transaction. <br />
<br />
Eve cannot change who the coins belong to by replacing Bob’s public key with her public key, because Alice signed the transfer to Bob using her private key, declaring that the coins which belonged to her now belong to Bob, and Alice's private key is kept secret from Eve. So if Charley accepts that the original coin was in the hands of Alice he will also accept the fact that this coin was later passed to Bob and now Bob is passing this same coin to him.<br />
<br />
===Preventing double-spending===<br />
The process described above does not prevent Alice from using a coin in more than one transaction. The following process does. This is the primary innovation behind Bitcoin.<br />
<br />
* Details about the [[Transactions|transaction]] are [[Network|sent and forwarded]] to all or as many other computers as possible.<br />
* A constantly growing chain of [[Blocks|blocks]] that contains a record of all transactions is collectively maintained by all computers (each has a full copy).<br />
* To be accepted in the chain, transaction blocks must be valid and must include [[proof of work]] (one block generated by the network every 10 minutes).<br />
* Blocks are chained in a way so that, if any one is modified, all following blocks will have to be recomputed.<br />
* When multiple valid continuations to this chain appear, only the longest such branch is accepted and it is then extended further.<br />
<br />
When Bob sees that his transaction has been included in a block, which has been made part of the single longest and fastest-growing block chain (extended with significant computational effort), he can be confident that the transaction by Alice has been accepted by the computers in the network and is permanently recorded, preventing Alice from creating a second transaction with the same coin. In order for Alice to thwart this system and double-spend her coins, she would need to muster more computing power than all other bitcoin users combined.<br />
<br />
===Anonymity===<br />
There are no bitcoin "accounts" to set up, no e-mail addresses and no user-names and passwords to give, just for owning bitcoins. Each balance is simply associated with a randomly generated public-private key pair and the money "belongs" to whoever has the private key and can sign transactions with it. Moreover, those keys do not have to be registered anywhere in advance, as they are only actually used if and when there is a transaction involving them. Transacting parties do not need to know each other's identity in the same way that a store owner does not know Bob's name is Bob when Bob goes and buys groceries with cash.<br />
<br />
A [[Address|Bitcoin address]] mathematically corresponds to a public key and looks like this:<br />
<br />
:15VjRaDX9zpbA8LVnbrCAFzrVzN7ixHNsC<br />
<br />
Each person can have many such addresses, each with its own balance, which makes it very difficult to know which person owns what amount. In order to protect his [[Anonymity|privacy]], Bob can even generate a new public-private key pair for each individual transaction. The Bitcoin software encourages this behavior by default. Continuing the example from above, when Charlie receives the bitcoin from Bob, Charlie will not be able to identify who owned the coin before Bob (not without asking Bob).<br />
<br />
You have completed reading our Bitcoin introduction!<br />
<br />
==Where to see and explore==<br />
You can directly explore the system in action by visiting the [http://blockexplorer.com/ Bitcoin Block Explorer].<br />
The site shows you the latest blocks in the block chain. The [[Block_chain|block chain]] contains the agreed history of all transactions that took place in the system.<br />
Note how many blocks were generated in the last hour which on average will be 6. Also notice the number of transactions and the total amount transferred in the last hour (last time I checked it was about 64 and 15K).<br />
This should give you an indication of how active the system is.<br />
<br />
Next, drill into one of these blocks.<br />
Start by noticing that the block's [[hash|hash]] begins with a run of zeros. This what made making it so difficult; a hash that begins with many zeros is much more difficult to find than a hash with few or no zeros. The computer that generated this block had to try many ''Nonce'' values (also listed on the block's page) until it found one that generated this run of zeros.<br />
Next notice the line titled ''Previous block'', each block contains the hash of the block that came before it, this is what forms the chain of blocks.<br />
Now notice all the transactions the block contains. The first transaction is the income earned by the computer that generated this block. It includes a fixed amount of coins created out of thin air and possibly fee collected from other transactions in the same block.<br />
<br />
Drill into any of the transactions and you will see how it is made from one or more amounts coming in and out.<br />
The fact that there can be more than one incoming and outgoing amounts, allow the system to join and break amounts in any possible way allowing for any fractional amount needed. Each incoming amount is a transaction from the past (which you can also drill to) coming from an address of someone and each outgoing amount is addressed to someone and will be part of a future transaction (which you can also drill too if it also had already taken place.)<br />
<br />
Finally you can drill into any of the [[Address|addresses]] and see what public information is available.<br />
<br />
To get an impression of the amount of activity on the Bitcoin network, you might like to visit the monitoring websites [[Bitcoin Monitor]] and [[Bitcoin Watch]]. The first shows a real-time visualization of events on the Bitcoin network and the second lists general statistics on the amount and size of recent transactions.<br />
<br />
===How many people use Bitcoin?===<br />
<br />
This is quite a difficult question to answer accurately. The best estimation is to count how many bitcoin clients connected to the network in the last 24 hours. We can do this as the client transmits its address to the other members of the network periodically. The estimate as of Sept 2011 is about 60,000 users. To get a more current estimate see [http://bitcoinstatus.rowit.co.uk/ Bitcoin Network Status Charts]<br />
