<div>=="only a proposal"==<br />
"Please note that the contents of this page is only a proposal, and in no way an official standard; at the time of writing it's not even all that popular."<br />
* Units are an objective measure; the cyan units are defined by SI, and the green by Tonal<br />
* As far as application to BitCoin, there is no such thing as "official", as it is an authorityless system<br />
--[[User:Luke-jr|Luke-jr]] 01:03, 8 March 2011 (GMT)<br />
<br />
Until tonal system is not widely used (at least it will be used by more than 1 person), it is rather confusing than useful to mention such units (even as proposal). So I simplify page to only units that is used.<br />
[[User:Aleš Janda|Aleš Janda]] ([[User talk:Aleš Janda|talk]]) 23:59, 26 August 2012 (GMT)<br />
<br />
<br />
Perhaps two pages are necessary, a Units_SI and a Units_Tonal and then a Units disambiguation page? - [[User:Sgornick|Sgornick]] ([[User talk:Sgornick|talk]]) 04:36, 13 November 2012 (GMT)<br />
* The colours work just fine for that. [[User:Aleš Janda|Aleš Janda]] doesn't seem to do anything but vandalise. --[[User:Luke-jr|Luke-jr]] ([[User talk:Luke-jr|talk]]) 02:24, 25 November 2012 (GMT)<br />
<br />
== Bugs ==<br />
<br />
The tonal column contains many unprintable characters (Firefox on Ubuntu 12.10). What are they supposed to mean? --[[User:Goonie|Goonie]] ([[User talk:Goonie|talk]]) 16:37, 5 April 2013 (GMT)<br />
* They're high-bit tonal digits, so they require a tonal-compatible font. [http://luke.dashjr.org/education/tonal/glyphs/fonts/Luxi/LuxiTonal.ttf Here is one] that I made to fix with the Luxi Mono font family. --[[User:Luke-jr|Luke-jr]] ([[User talk:Luke-jr|talk]]) 16:43, 5 April 2013 (GMT)<br />
<br />
== User friendly subunit ==<br />
We need a user friendly bitcoin subunit. The users usually use currencies with two decimal positions, so the proposal is to use the 1e6 subunit to have this two decimal positions.<br />
The proposal for the name of this unit is microcoin where 1 bitcoin = 1,000,000.00 microcoins. We need also a currency symbol for this subunit, the proposal is to use the existing symbol <br />
whith unicode \u289 and html code &#649;<br />
You can also read the [[Bitcoin_symbol]] discussion<br />
What do you think about?<br />
<br />
* I think you mean micro-bitcoin, which already exists... --[[User:Luke-jr|Luke-jr]] ([[User talk:Luke-jr|talk]]) 02:51, 29 October 2014 (UTC)<br />
* @Luke-jr I'm thinking about microcoin, is shorter than microbitcoin and in my opinion more user friendly because of the fact that microbitcoin seems <br />
as a micro part of bitcoin and psychologically the user wants to have a whole not a part of a coin, so bitcoin is the unit and equivalent to 1,000,000.00 of microcoins. <br />
You can read the [http://simple.wikipedia.org/wiki/Bitcoin Wikipedia Bitcoin units] as microcoin [[User:Igarciaes|Igarciaes]] ([[User talk:Igarciaes|talk]]) 07:46, 29 October 2014 (UTC)<br />
<br />
** "micro-" is a well-defined SI prefix. If you want to give it a custom name, I suggest you may be more successful with something unique. Removing the "bit" from "bitcoin" doesn't psychologically remove "micro-" anyway. Wikipedia is a medium of propaganda, not a relevant source. --[[User:Luke-jr|Luke-jr]] ([[User talk:Luke-jr|talk]]) 11:05, 29 October 2014 (UTC)<br />
*** Thank you @Luke-jr<br />
<br />
== Split that page into Standard (or "Commonly Accepted") and Tonal sections ==<br />
<br />
I think this table would be much less confusing if we split the tonal units to a separate table. Very few people use the tonal system, so it makes sense to differentiate it from the commonly accepted units. [[User:Aceat64|Aceat64]] ([[User talk:Aceat64|talk]]) 22:39, 27 February 2015 (UTC)<br />
<br />
Hm, there's only 3 more commonly used units (BTC, mBTC/bits, and satoshis) - maybe it would be better to just have a dedicated text about those three above the table? Another possibility is some icon by them in the table. --[[User:Luke-jr|Luke-jr]] ([[User talk:Luke-jr|talk]]) 06:55, 28 February 2015 (UTC)<br />
<br />
== Remove Tonal Bitcoins ==<br />
<br />
I think any mentions of Tonal Bitcoins should be removed from this page as this wiki is for Bitcoin, not altcoins. The creator of Tonal Bitcoins calls it "First (and best) altcoin ever: Tonal Bitcoin (TBC)" - https://bitcointalk.org/index.php?topic=218388.0 , and seeing as alts were removed from such pages as [[List of address prefixes]] (by Luke - https://en.bitcoin.it/w/index.php?title=List_of_address_prefixes&diff=48686&oldid=24158 ), these units that even fewer people care about should also be removed.<br />
<br />
[[User:ThePiachu|ThePiachu]] ([[User talk:ThePiachu|talk]]) 01:52, 1 March 2015 (UTC)<br />
: NAK. There is significant code that exists for Tonal Bitcoin, it has a strong educational and adoption-assist component, and it is actively maintained and used by Luke and the most significant centrally-managed Bitcoin pool. [[User:Midnightmagic|Midnightmagic]] ([[User talk:Midnightmagic|talk]]) 22:57, 1 March 2015 (UTC)<br />
<br />
::I fully support the removal of Tonal Bitcoin information from this page. When present, the irrelevant and extremely esoteric Tonal content commingles with pertinent Bitcoin information resulting in unnecessary confusion. I strongly dispute [[User:Midnightmagic|Midnightmagic]]'s contention that including this distracting information assists in user adoption. [[User:Chinawat|Chinawat]] ([[User talk:Chinawat|talk]]) 17:37, 5 March 2015 (UTC)<br />
<br />
:::I agree. I have looked into other systems (including Tonal) long before I had even heard of Bitcoin, and think that they're nice, but in the end, they simply don't belong here. Tonal Bitcoin is an idea that deserves its own page, but should be confined therein. Tonal will (unfortunately) probably never reach the stage of adoption that makes it notable enough to be listed here, with units that are actually used. (That said, I think we should also omit the almost entirely unused SI units (hecto-,mega-,etc.)) [[User:Taras|Taras]] ([[User talk:Taras|talk]]) 21:33, 5 March 2015 (UTC)<br />
<br />
Any updates? I'd like to keep tonal off the units page, as discussion/consensus here seems to imply, but I'm getting some pushback by [[User:Midnightmagic]] and [[User:Luke-jr]]. Thoughts? Thanks, [[User:Bitcoinomy|Bitcoinomy]] ([[User talk:Bitcoinomy|talk]]) 16:55, 19 August 2015 (UTC)</div>Bitcoinomyhttps://en.bitcoin.it/w/index.php?title=User_talk:Bitcoinomy&diff=58396User talk:Bitcoinomy2015-08-19T12:49:17Z<p>Bitcoinomy: +minor word and case.</p>

<div>While units in Bitcoin usually follow the Standard Metric Notation system, this page lists the most commonly-used units. These can be expressed in any number of ways, from using some form of the prefix to an abbreviation of both the prefix and adding Bitcoin. Bitcoin as a unit of account is sometimes written without capitalization, but since it is not a genericized term yet and refers to one specific type of crypto-currency, capitalization is left as an exercise for the reader.<br />

{{p-full}}</div>Bitcoinomyhttps://en.bitcoin.it/w/index.php?title=Talk:Tonal_Bitcoin&diff=54899Talk:Tonal Bitcoin2015-03-05T16:23:43Z<p>Bitcoinomy: adding unsigned tag and a few deleted comments.</p>
<hr />
<div>This is for discussion, '''not trolling'''. Note that this is not an encyclopedia, and does not have any "notability" requirements. If you don't want to use Tonal, don't. Trolling is not acceptable and will be deleted. Reasoned criticism is welcome in the "Criticism" section of the page. {{Unsigned|Luke-jr|03:50, 28 August 2012}}<br />
<br />
<br />
I have no legitimate stake in the matter, I made a few edits that I hope remove POV and still embrace the idea of Tonal Bitcoin. This is Raize, I am sorry I am not familiar enough with wiki editing to provide my signature. --[[User:Raize|Raize]]<br />
<br />
==Proposal for deletion==<br />
<br />
This page should be deleted until there is a working, supported, maintained Tonal Bitcoin client. Vaporware doesn't belong on this wiki, you'll get articles on CosbyCoin and UnicornCoin...<br />
[[User:Gavinandresen|Gavin Andresen]] ([[User talk:Gavinandresen|talk]]) 23:28, 25 May 2013 (GMT)<br />
:Oh, a new player entered the arena in Luke's religious war :) The heavyweigh champion Gavin Andresen! I'm impressed! --[[User:Giszmo|Giszmo]] ([[User talk:Giszmo|talk]]) 01:48, 26 May 2013 (GMT)<br />
<br />
==Proposal for deletion==<br />
<br />
I propose to delete this article on the following grounds.<br />
<br />
# "Tonal bitcoin" ''is'' Bitcoin. Tonal Bitcoin only refers to the choice of the bitcoin user to employ a different representation of standard bitcoin balances. Instead of using decimal, the originator proposes using tonal units. If we follow this approach to the extreme, we could also use any base X system. It comes down to this: If you have a bitcoin balance of X in decimal notation, you can convert this to a balance Y in tonal units.<br />
# There is almost no information about tonal bitcoin available on the web attesting to its insignificance. All information that is available seems to come from a single source. To make matters worse, the information that is available is extremely confusing and poorly written.<br />
# No one, with the possible exception of one person, use "tonal bitcoin" units.<br />
# Not one exchange or business uses Tonal bitcoin units (to my knowledge).<br />
<br />

<br />
: '''1)''' Exactly why it is on-topic to the wiki, and should ''not'' be deleted; '''2)''' This wiki is just as relevant to the web as any random altcoin website, and this wiki explicitly permits and encourages original content and original research, unlike Wikipedia which is merely an encyclopedia; '''3)''' I know multiple people who use TBC (though I won't do so publicly so they can be trolled) - and in any case, significance and/or notability is not a concern of this wiki (see [[:Bitcoin:About|the wiki about/policy page]]); '''4)''' Again, irrelevant. --[[User:Luke-jr|Luke-jr]] ([[User talk:Luke-jr|talk]]) 16:10, 24 August 2014 (UTC)<br />
<br />
:: I agree that this should not be deleted. This is not Wikipedia, we don't have a notability policy, and explicitly allow technical or niche material relating to bitcoin. [[User:Nanotube|Nanotube]] ([[User talk:Nanotube|talk]]) 16:31, 24 August 2014 (UTC)<br />
<br />
I think this article should be deleted as this wiki is for Bitcoin, not altcoins. The creator of Tonal Bitcoins calls it "First (and best) altcoin ever: Tonal Bitcoin (TBC)" - https://bitcointalk.org/index.php?topic=218388.0 , and seeing as this wiki has no article on [[Litecoin]] or [[Dogecoin]], this website should go as well. Nobody cares about this, and it's just useless clutter on pages like this or [[Units]].<br />
<br />
[[User:ThePiachu|ThePiachu]] ([[User talk:ThePiachu|talk]]) 01:49, 1 March 2015 (UTC)<br />
<br />
:This just seems petty and vindictive to me, and also needlessly drama inducing. This wiki exists to cover Bitcoin things, it's fine if it covers niche and obscure aspects of the Bitcoin ecosystem. That this wiki isn't free hosting and advertisement for your choice of competing currencies is no reason to justify deleting things on the wiki. --[[User:Gmaxwell|Gmaxwell]] ([[User talk:Gmaxwell|talk]]) 06:26, 1 March 2015 (UTC)<br />
<br />
::A fair point. That being said, due to the nonexistent userbase of the Tonal Bitcoins, I would keep them away from non-relevant pages of the wiki, such as the mentioned [[Units]]. [[User:ThePiachu|ThePiachu]] ([[User talk:ThePiachu|talk]]) 07:31, 1 March 2015 (UTC)<br />
<br />
:::I use base 27 for all my bitcoin balances and have made up names for all the numbers and powers of 27. They're named after my cats. Can I add them to the [[Units]] page?

<div>A Perl module which interfaces with the now defunct [[MtGox#API|Mt. Gox API]]. It supports both the legacy API and the "key-secret" API (v0).<br />
<br />
This [[:Category:Open Source|open source]] tool is useful to merchants as it helps determine "market clearing rate". This technique is needed because the number of units offered at the "best bid" or "best ask" are inadequate for a trade of size to execute. Thus the market clearing rate determines the weighted price for the entire trade to execute.<br />
<br />
The module was written by the operator of [[CoinPal]] and [[CoinCard]] and was announced on February 9, 2011<ref>[http://www.bitcointalk.org/index.php?topic=3287.0 MtGox API Perl module]</ref><br />

<div>'''Tor''' is a distributed 'onion' network, that makes it more difficult for an adversary to track any one peer on the network. Tor also is very useful to access the 'uncensored' internet in countries such as China and Iran. Preserving privacy means not only hiding the content of messages, but also hiding who is talking to whom (traffic analysis). Tor provides anonymous connections that are strongly resistant to both eavesdropping and traffic analysis.<br />
<br />
Bitcoin can run easily on the Tor network. <br />
<br />
=Tor installation & use=<br />
''todo explain: onion routing (how tor network helps to anonymize), encryption used, exit nodes, routers''<br /><br />
<br />
Please follow the instructions provided with installation files and read the [http://www.torproject.org/download/download.html.en#warning list of warnings]. ''Tor doesn't magically anonymize all your traffic just because you install it.''<br /><br />
Down the page you can find examples how to configure applications to use Tor to anonymize the origin of your traffic.<br /><br />
[http://www.torproject.org/docs/tor-doc-windows.html.en This] is a detailed installation guide for Windows. Before you setup Bitcoin or mIRC to use Tor, please install Tor and start in.<br /><br />
[[{{ns:file}}:20110109-tor-running.png]] On the taskbar of your compute you'll see a small green onion when Tor is running.<br />
[[{{ns:file}}:20110109-bitcoin-mirc-vidalia.png]]<br />
<br />
=GUI=<br />
Once you have your Tor client up & running, you can configure your Bitcoin client to use it.<br /><br />
Select in menu Settings -> Options<br /><br />
[[{{ns:file}}:20110108-btc-options.png]]<br /><br />
<br />
Check "Connect through socks 4 proxy" with the address 127.0.0.1 and port 9050 (the Tor default port number)<br /><br />
[[{{ns:file}}:20110108-btc-client-tor-as-proxy.png]]<br /><br />
Configuring an application to use Tor is also called to torify it.<br />
(needs a brief howto here)<br />
<br />
''the note about bitcoin-otc promote on a more appropriate place in this page? reference to trading and IRC''<br />
Conducting business using [[bitcoin-otc]] can be done more anonymously when directly connected to a Freenode IRC hidden service.<br />
<br />
=bitcoind=<br />
<br />
Run bitcoind with -proxy=127.0.0.1:9050 (or whatever your SocksPort is).<br />
<br />
bitcoind will detect that you are using a proxy on 9050 and will force the "nolisten" flag. If you are not running tor on 9050, you need to set "nolisten" manually otherwise you will listen on your public IP and possibly reveal that you are running a node.<br />
<br />
=Hidden services=<br />
These services are running within the tor network. You can connect to them for example using the -connect= parameter to bitcoind. Note that you do not need to use them - tor can also anonymize your normal internet traffic, including bitcoin connections. There are some technical reasons why hidden services may be beneficial, see the tor documentation if you're really interested.<br />
<br />
Services are listed at [[Fallback_Nodes#Tor_network]] along with instructions for using them.<br />
<br />
=Pooled Mining=<br />
<br />
Some mining pools are available as a hidden service on the tor network. Any pool can be reached over tor. The general methodology here is to tell your mining client to use your local Tor proxy. This is client specific but there are some helpful hints.<br />
<br />
==Linux / BSD==<br />
<br />
Any client can have its traffic routed via Tor by using the torify command and invoking the miner with that. Another method is to set the http_proxy environment variable as some miners use libraries which support that.<br />
<br />
==Windows / OS X==<br />
<br />
It is possible to set the http_proxy environment variable as some miners use libraries which support that.<br />
<br />
=mIRC=<br />
<br />
mIRC is a popular IRC client. This is a guide how to connect to Freenode IRC using Tor + SASL + mIRC.<br /><br />
==Register your nick with freenode nickserv<br />==<br />
Freenode only allows SASL authenticated users to connect to the onion IRC server. SASL authentication works only with a registered nickname.<br /><br />
Connect to Freenode IRC without using tor & execute<br /><br />
/msg nickserv register <password> <email><br /><br />
<br /><br />
You will see something like this<br /><br />
-NickServ- An email containing nickname activation instructions has been sent to <email><br /><br />
-NickServ- If you do not complete registration within one day, your nickname will expire.<br /><br />
<br /><br />
To finish your nick registration go the provided email and copy/paste the command from e-mail to irc.<br /><br />
<br />
==Add SASL support to your mIRC installation<br />==<br />
Download the SASL.dll and sasl.mrc files and copy them to your mIRC installation directory<br /><br />
Load sasl.mrc script (Alt + R to open script editor, Ctrl + L to load file, browse to sasl.mrc, press OK or "save & exit").<br /><br />
[[{{ns:file}}:20110109-sasl-script-loaded.png]]<br /><br />
Type /dialog -m SASL.main SASL.main to open the SASL connection manager.<br /><br />
[[{{ns:file}}:20110109-sasl-dialog.png]]<br /><br />
Add Freenode entry.<br /><br />
[[{{ns:file}}:20110109-sasl-manager.png]][[{{ns:file}}:20110109-sasl-manager-network.png]]<br /><br />
Network is Freenode.<br /><br />
Username and NS Password must match your nickserv reservation.<br /><br />
Auth Type can be PLAIN<br /><br />
<br />
==setup mIRC to use Tor<br />==<br />
Add the entry for Freenode onion IRC server<br /><br />
[[{{ns:file}}:20110109-onion-irc-add.png]]<br /><br />
Configure mIRC to use a Proxy (your local Tor proxy)<br /><br />
[[{{ns:file}}:20110109-mirc-proxy.png]]<br /><br />
<br /><br />
Now you should be able to connect.<br /><br />
[https://www.bitcointalk.org/index.php?topic=2602 Bitcoin forum where this topic is discussed]<br />
<br />
=How Tor works=<br />
Unlike Freenet, I2P, etc., Tor's security is very well-defined. While weaknesses do exist (described below), they have been known since Tor was created, and new weaknesses of significance are not expected.<br />
<br />
Tor sends TCP packets over 3 (normal) or 7 (hidden services) Tor relays. This is why it is so slow: your packet might have to go through 100 computers (counting Internet routers) before it reaches its destination. Tor uses multiple ''layers'' of encryption that are ''pulled away'' for each node. Hence the name '''T'''he '''O'''nion '''R'''outer, which is always capitalized as '''Tor''', and never TOR or t.o.r.<br />
<br />
Say that I want to connect to bitcoin.org through Tor. I first select three Tor relays that I know about. Then, I send a message to my ISP that looks like this:<br />
Send to this IP: <IP of Relay1><br />
<Encrypted data for Relay1><br />
When Relay1 receives this, he decrypts the payload using his private key. The payload contains this:<br />
Send to this Tor node: <Relay2><br />
<Encrypted data for Relay2><br />
Relay2 decrypts his payload:<br />
Send to this Tor node: <Relay3><br />
<Encrypted data for Relay3><br />
Relay3 receives the real TCP payload, which he sends to the destination:<br />
Send to this IP: <IP of destination><br />
<Unencrypted payload><br />
The payload is not and can not be further encrypted by Tor. However, if the protocol itself uses encryption (HTTPS, SSH, etc.), the data will be encrypted. This means that the last node (the ''exit node'') can see everything you do on HTTP sites, and can steal your passwords if they are transmitted unencrypted. Many people become exit nodes just so they can view this information -- Tor is much more dangerous than open WiFi for snooping!<br />
<br />
The encryption arrangement described above ensures that no single Tor node knows both the sender and the destination. Relay1 and your ISP know that you are using Tor and sending a packet at a certain time, but they don't know what you're sending or who you're sending to. Relay3 knows exactly what you're sending, but he can't determine who is sending it because Relay2 and Relay1 are blocking him. All three relays need to work together in order to conclusively connect the sender and the destination.<br />
<br />
However, Tor is weak to a ''timing attack'' that allows only two participants in certain positions to determine the sender with high accuracy. Consider this Tor connection:<br />
Sender <-> S-ISP <-> Relay1 <-> Relay2 <-> Relay3 <-> D-ISP <-> Destination<br />
If the sender's ISP (S-ISP) and the destination are working together, they can record the size and times of packets sent and received. Over a large number of packets, they can determine with very high accuracy that the sender is, in fact, the person sending packets to the destination. This requires active surveillance or detailed logging by both sides. Relay1 can also perform the same role as S-ISP.<br />
<br />
Additionally, more configurations are possible if the underlying connection is not encrypted (normal HTTP, for example):<br />
*S-ISP & Relay3<br />
*Relay1 & Relay3<br />
*S-ISP & D-ISP<br />
*Relay1 & D-ISP<br />
This second set can always see that the sender is connected to the destination, but they can only see what the sender is doing on the site if the connection is not encrypted. (Pathnames are encrypted in HTTPS.)<br />
<br />
Because the first relay (the ''entry node'') is a weak point in the connection, Tor takes certain defensive measures. When you first start Tor, it chooses three ''entry guards'' that don't change for the entire time that you run Tor. You will always use one of those three unless one goes down. If all of those nodes are safe and your ISP is safe, then you are OK.<br />
<br />
These timing attacks are of special importance to Bitcoin because anyone can be the "destination" in a connection. Packets are broadcast to every peer in the Bitcoin network. This might allow your ISP alone to associate your transactions to you without much difficulty. However, a timing attack relies on receiving at least several dozen packets from the sender, so the "destination" might actually have to be one of your direct Bitcoin peers. It's not too difficult to flood the Bitcoin network with peers, though. Because of this attack, it is wise to use an [[EWallet]] instead of the Bitcoin client when using Tor.<br />
<br />
To discover Tor relays, Tor uses a centralized directory server model. There are nine authoritative directory servers. To become a relay, you register with one of these. The directory servers share their data and produce a ''network status consensus'' document every so often containing all Tor nodes. Tor clients don't connect directly to the authoritative directory servers -- they connect to one of many ''directory mirrors'', which have a copy of the network status consensus. Since there is no peer-to-peer bootstrap mechanism in Tor, the entire network can be destroyed if half of the authoritative directory servers are destroyed, and the entire network can be subverted if half of the authoritative directory servers become evil.<br />
<br />
Hidden services allow both the sender and destination to remain anonymous. A hidden service connection is made like this:<br />
*The destination tells several Tor relays to act as ''introduction points'' for the hidden service. The destination stays connected to all of these introduction points through a regular three-node Tor circuit.<br />
*The destination registers these introduction points on a Tor DHT. The introduction points are associated with the first 16 characters of an encoded SHA-1 hash of the destination's key. This is the information in .onion addresses. The use of SHA-1 is a possible weakness.<br />
*The sender creates a four-node Tor circuit. The fourth node is called the ''rendezvous point''.<br />
*The sender searches the DHT for the introduction points of the desired hidden service. The sender connects to one through a regular three-node Tor circuit and, through the introduction point, tells the destination about the rendezvous point he has chosen.<br />
*The destination connects to the rendezvous point over a three-node Tor circuit. The sender and destination are now in contact over a seven-node connection.<br />
<br />
For clients, hidden services are more secure than encrypted Tor HTTPS connections because:<br />
*If the destination remains anonymous, they are less likely to become controlled by an evil party.<br />
*The destination's ISP isn't involved as they are in the HTTPS case. Only these configurations are possible for a timing attack:<br />
**S-ISP & Destination<br />
**Relay1 & Destination<br />
<br />
Running a hidden service is more dangerous, however. A simple intersection attack can be performed by the hidden service's ISP alone:<br />
*Your Internet service is cut off.<br />
*If the hidden service went down at that exact moment, you are unmasked.<br />
The same sort of timing attacks as above are also possible.<br />
<br />
See the [http://www.usenix.org/events/sec04/tech/full_papers/dingledine/dingledine_html/index.html Tor design paper] for more info.<br />
<br />
=Exchange Restrictions=<br />
<br />
Some exchanges will treat activity occurring through Tor with greater precautions. For instance, the now-defunct Mt. Gox signup sheet read:<br />
: Please be advised that accessing your account via the Tor network and/or public proxies may result in a temporary suspension of your account, and having to submit AML documents.<br />

<hr />
<div>==Introduction==<br />
<br />
Wallet security can be broken down into two independent goals:<br />
# Protecting your wallet against loss.<br />
# Protecting your wallet against theft.<br />
<br />
In the case that your current wallet hasn't been protected adequately (e.g. put online with a weaker password):<br />
# Making a new secure wallet, using appropriate long-term protection.<br />
<br />
''For a brief overview see also: [[Wallet Security Dos and Don'ts|Wallet Security Dos and Don'ts]]''<br />
<br />
==Paper Wallets==<br />
[[Paper wallet]]s can be used to store bitcoins offline in non-digital format. Using securely generated paper wallets significantly decreases the chances of your bitcoins being stolen by hackers or computer viruses.<br />
<br />
Fundamentally, a paper wallet is merely a physical record of a [[private key]] (most commonly written as a sequence of fifty-one alphanumeric characters beginning with a '5') and its corresponding [[public key]]. The private key is used to prove your right to spend the bitcoins transferred to the paper wallet, and as such should be kept hidden and secret. If the private key on a paper wallet is exposed (for example in a photograph) then the wallet may be "swept" by anyone who sees the key. To guard against accidental revelation, the private key displayed on the paper wallet may be encrypted using a password ("BIP38") or split into several different parts ("Shamir's secret sharing scheme"). 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 />
You can send bitcoins to the public address on your paper wallet as often as you like, and they will be inaccessible until the private key is imported into a "live" wallet. You can use a service such as [[BlockChain.info]] to verify the balance of your paper wallet, which is a matter of public record. As of version 0.6.0, the bitcoin QT software has a command line feature called "importprivkey" that can load private keys. Online exchanges and wallets such as [[Coinbase (business)|Coinbase]] and BlockChain.info have features for importing (or "sweeping") paper wallet private keys as well.<br />
<br />
=== Software for generating paper wallets ===<br />
<br />
Some [[Paper wallet|paper wallet generators]] have been written entirely in HTML/JavaScript to make it fairly easy to generate paper wallets on virtually any operating system. Although these generators use a web browser, they are generally capable of running offline since address generation happens entirely within the web browser. It's advisable to use those services from [https://en.wikipedia.org/wiki/Live_CD live disc], to ensure that private keys are not compromised by spyware. <br />
<br />
To generate a safer paper wallet, first save the paper wallet generating code to a newly-formatted USB stick and verify the integrity (SHA1 hash or PGP signature) of the code. Then "clean-boot" your computer with a bootable CD (such as a Linux Live CD) while disconnected from the Internet. Insert the USB stick and open the wallet generator's HTML file using a web browser. Print your paper wallets or store them on external media (do not save them on the computer), and then shut down the computer. You may need to load an appropriate printer driver in order to print while booted from the live CD.<br />
<br />
=== Tips for making paper wallets ===<br />
<br />
* Disconnecting from the Internet guarantees that that the paper wallet generator is truly self-contained and isn't transmitting your keys online. <br />
<br />
* Verifying the integrity of the code (and the trustworthiness of the author) is important to make sure a hacker hasn't modified the HTML so that it generates predictable addresses instead of truly random keys.<br />
<br />
* Using a very basic printer is advisable since high-end office printers may have WiFi or internal storage that keeps a cache of printed documents.<br />
<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 and private keys 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 key can then be intercepted while you enter it, so only enter a Bitcoin private key into your computer when your intent is to redeem its value ''immediately''.<br />
<br />
== Hardware wallets ==<br />
[[Hardware wallet]]s are a major effort to provide a good combination of enhanced security and usability.<br />
<br />
So far only [http://www.pi-wallet.com/ Pi Wallet] is operational.<br />
<br />
==Importance of security updates==<br />
<br />
No software is perfect, and from time to time there may be security vulnerabilities found in your Bitcoin client as well.<br />
Be sure you keep your client updated with the latest bug fixes, especially when a new vulnerability is discovered.<br />
We maintain a [[CVEs|list a known vulnerabilities]] on this wiki - you can watch that page to get updates.<br />
Note that you ''don't'' need to be running the latest major client version: some clients, including the popular Bitcoin-Qt, have older versions available with bugfix-only updates.<br />
<br />
==Securing the Bitcoin-QT or bitcoind wallet==<br />
<br />
Bitcoin transactions send Bitcoins to a specific public key. A Bitcoin address is an encoded hash of a public key. In order to use received Bitcoins, you need to have the private key matching the public key you received with. This is sort of like a super long password associated with an account (the account is the public key). Your Bitcoin wallet contains all of the private keys necessary for spending your received transactions. If you delete your wallet without a backup, then you no longer have the authorization information necessary to claim your coins, and the coins associated with those keys are lost forever.<br />
<br />
The wallet contains a pool of queued keys. By default there are 100 keys in the [[key pool]]. The size of the pool is configurable using the "-keypool" command line argument. When you need an address for whatever reason (send, “new address”, generation, etc.), the key is not actually generated freshly, but taken from this pool. A brand new address is generated to fill the pool back to 100. So when a backup is first created, it has all of your old keys plus 100 unused keys. After sending a transaction, it has 99 unused keys. After a total of 100 new-key actions, you will start using keys that are not in your backup. Since the backup does not have the private keys necessary for authorizing spends of these coins, restoring from the old backup will cause you to lose Bitcoins.<br />
<br />
Creating a new address generates a new pair of public and private keys, which are added to your wallet. Each keypair is mostly random numbers, so they cannot be known prior to generation. If you backup your wallet and then create more than 100 new addresses, the keypair associated with the newest addresses will not be in the old wallet because the new keypairs are only known after creating them. Any coins received at these addresses will be lost if you restore from the backup.<br />
<br />
The situation is made somewhat more confusing because the receiving addresses shown in the UI are not the only keys in your wallet. Each Bitcoin generation is given a new public key, and, more importantly, each sent transaction also sends some number of Bitcoins back to yourself at a new key. When sending Bitcoins to anyone, you generate a new keypair for yourself and simultaneously send Bitcoins to your new public key and the actual recipient's public key. This is an anonymity feature – it makes tracking Bitcoin transactions much more difficult.<br />
<br />
So if you create a backup, do more than 100 things that cause a new key to be used, and then restore from the backup, some Bitcoins will be lost. Bitcoin has not deleted any keys (keys are never deleted) – it has created a new key that is not in your old backup and then sent Bitcoins to it.<br />
<br />
== Making a new wallet ==<br />
<br />
If a wallet or an encrypted wallet's password has been compromised, it is wise to create a new wallet and transfer the full balance of bitcoins to addresses contained only in the newly created wallet. Examples of ways a wallet may be compromised are through password re-use, minimal strength passwords, computer hack or virus attack.<br />
<br />
There are a number of ways to create a new wallet with Bitcoin-QT or bitcoind but this is a process that has been tested with bitcoind 0.6.3. We use the copy command to minimize the chance of any data loss but you are warned to make backups of any wallet.dat that holds a balance for you.<br />
<br />
:1. Shut down the Bitcoin program.<br />
:2. Find and make a backup of the "compromised" wallet.dat file and rename it, perhaps adding a short description:<br />
:::wallet.dat -> wallet-compromised.dat<br />
:Depending on your OS, the wallet file will be located at:<br />
:::Windows: %APPDATA%\Bitcoin\<br />
:::Linux: ~/.bitcoin/<br />
:::Mac: ~/Library/Application Support/Bitcoin/<br />
:3. Start the Bitcoin program and it will create a new wallet.dat. You may then encrypt the wallet as desired and make a new backup.<br />
:4. Once you've made a new wallet, you can obtain one or more addresses and copy them into a text editor. After obtaining the new address(es), shut down the Bitcoin program, make a backup of the new wallet.dat file and copy it to a new file named wallet-new.dat.<br />
:5. Copy the wallet-compromised.dat file back to wallet.dat, start the Bitcoin program and transfer your balance to the new address(es) you put in your text editor. Once the balance is back to 0 for your compromised wallet, you may want to wait a couple minutes or for a confirmation or check block explorer to be sure the transactions have been broadcasted. Then you may shut down the Bitcoin program.<br />
:6. Rename wallet.dat to wallet-compromised.dat. <br />
:7. Rename wallet-new.dat to wallet.dat.<br />
<br />
You should now have a new wallet with all the bitcoins from the old wallet.<br />
<br />
==Making a secure workspace==<br />
<br />
If you are using your computer to handle bitcoins, a wallet, Bitcoin-related passwords, or Bitcoin private keys, you must take care that the system is free of malware, viruses, keyloggers, remote access tools, and other tools that may be used to make remote copies of any of the above. In the case that your computer is compromised, the precautions taken below may provide additional protection.<br />
<br />
===Debian-based Linux===<br />
<br />
==== Store all into an encrypted folder (Tomb) ====<br />
<br />
Tomb is a simple tool to manage encrypted storage on GNU/Linux. Among its features are bind-hooks to set up a tomb's contents in the place where other programs expect them, for example in our case mount -o bind the .bitcoin directory in a user's home.<br />
<br />
First install tomb from https://files.dyne.org/tomb (homepage is on http://www.dyne.org/software/tomb)<br />
<br />
Among the requirements: zsh, cryptsetup, pinentry-curses, gnupg, sudo.<br />
<br />
Recommended: wipe, dcfldd, steghide, qrencode.<br />
<br />
Then create a tomb (we name it bitcoin) with three commands:<br />
<br />
<code>tomb dig -s 100 bitcoin.tomb</code><br />
<br />
<code>tomb forge bitcoin.tomb.key</code><br />
<br />
<code>tomb lock bitcoin.tomb -k bitcoin.tomb.key</code><br />
<br />
Then open it<br />
<br />
<code>tomb open bitcoin.tomb</code><br />
<br />
This will require you to input again the password you selected.<br />
<br />
Once open the tomb contents are in /media/bitcoin.tomb<br />
<br />
Move there your bitcoin wallet:<br />
<br />
<code>mv ~/.bitcoin /media/bitcoin.tomb/my-safe-wallet</code><br />
<br />
Then create a file "/media/bitcoin.tomb/bind-hooks" and put a single line:<br />
<br />
<code>my-safe-wallet .bitcoin</code><br />
<br />
Which means that every time the tomb is open, the directory my-safe-wallet needs to be bound to ~/.bitcoin. Just make sure an empty ~/.bitcoin directory exists in your home.<br />
<br />
Now close the tomb and store its keys safely, make sure you memorize the password. Have a look at Tomb's documentation, there is a number of things you can do like steganography or printing out keys on a paper to hide and such.<br />
<br />
That's it. Every time you like to access your wallet open the tomb and the .bitcoin will be in place. One can also store the bitcoin binary inside the tomb and even start the bitcoin client using the exec-hooks. Tomb's manual page "man tomb" explains the possibilities.<br />
<br />
The advantage of this approach over an encrypted home is that it becomes extremely portable across computers and even online shells: a Tomb is just a file and its key can be stored far away, on different shells, usb sticks or mobile phones.<br />

==== Secure the whole user home directory ====<br />
The first step is to make a [http://www.howtogeek.com/howto/ubuntu/add-a-user-on-ubuntu-server/ new user]. In order for that new user to have an encrypted home directory, you'll first need the encryption utility. Run:<br />
<br />
<code>sudo apt-get install ecryptfs-utils</code><br />
<br />
Now you're ready to create a new user<br />
<br />
<code>sudo adduser --encrypt-home new_user_name</code><br />
<br />
You'll need to come up with a [[#Choosing_A_Strong_Password|secure]] new password for that user.<br />
<br />
When you get to the prompt 'Enter the new value, or press ENTER for the default', just keep hitting ENTER.<br />
<br />
Then switch user to the new user. To get to the new user you can use the switch user icon for your system, which on Ubuntu is in the 'System/Quit' screen, or if there is no switch icon on your system you can log out and log back in as the new user.<br />
<br />
Since the home folder of this user is encrypted, if you're not logged in as that user, data that is saved there can't be browsed, even by a root user. If something goes wrong with your system, and you need to decrypt the new user's files, you'll need its decryption key.<br />
<br />
<code>ecryptfs-unwrap-passphrase</code><br />
<br />
It will ask you for your user's password and give you the decryption key. '''WRITE DOWN OR SAVE THE CODE IT RETURNS''' because you will need it if you ever have to pull your data off while the OS is not working. (You can run it again later if you need to, but run it now so that you can get your data if your Linux install gets botched.)<br />
<br />
The encrypted folder data is not encrypted while it's in memory, and so if it's ever sent to the swap partition it can be stolen from there unless that too is encrypted - be aware that this will mean you cannot use Hibernate anymore, as the bootloader won't be able to restore the hibernation data.<br />
<br />
<code>ecryptfs-setup-swap</code><br />
<br />
Then click on a folder in the new user to display the file browser, then keep going up folders until you see the new user home directory, then right click to bring up the Properties dialog, then click on the Permissions tab, then in the Others section, set the folder access to None.<br />
<br />
For secure browsing, open Firefox, and then go into the Edit menu and click Preferences. Starting from the left, click on the General tab, and in the 'Startup/When Firefox starts' pop up menu, choose 'Show a Blank Page'. Then click on the Content tab, and deselect 'Load images automatically' and deselect 'Enable JavaScript'. Then click on the Privacy tab, and in the 'History/Firefox will' pop up menu, choose 'Never remember history'. Then click on the Security tab, and in the Passwords section, deselect 'Remember passwords for sites' and deselect 'Use a master password'. Then click on the Advanced tab, then click on the Update tab, and then in the 'Automatically check for updates to' section, deselect 'Add-ons' and 'Search Engines'.<br />
<br />
When JavaScript is disabled, the [http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.3.23/bitcoin-0.3.23-linux.tar.gz/download Linux download page] will not download automatically, so you'll have to click on the 'direct link' part of the "Problems with the download? Please use this 'direct link' or try another mirror." line.<br />
<br />
===Mac===<br />
This solution '''does not scale'''; the amount of needed space can grow beyond the image size.<br />
<br />
===Windows===<br />
<br />
Due to the frequency with which Windows computers are compromised, it is advised to encrypt your wallet or to keep your wallet on an encrypted disk image created by third-party software, such as [http://www.truecrypt.org/ TrueCrypt] (open source) or [http://www.jetico.com/encryption-bestcrypt/ Jetico BestCrypt] (commercial). This also applies to the storage of passwords, private keys and other data that can be used to access any of your Bitcoin balances.<br />
<br />
Assuming that you have installed the Windows Bitcoin client and run it at least once, the process is described below.<br />
<br />
<p><b>To mount the Bitcoin data directory on an encrypted drive</b></p><br />
<ol start=1 type=1><br />
<li>Use the third-party disk image encryption program of your choice to create and mount an encrypted disk image of at least 5GB in size. This procedure stores the entire block chain database with the wallet.dat file so the required size of the encrypted disk image required may grow in the future.</li><br />
<li>Locate the Bitcoin data directory, and copy the directory with all contents to the encrypted drive.<br />
<p>For help finding this directory, see <b>[[Securing_your_wallet#Locating_Bitcoin_s_data_directory|Locating Bitcoin's Data Directory]]</b>.</p></li><br />
<li>Create a Windows shortcut that starts Bitcoin with the <code>-datadir</code> parameter and specifies the encrypted drive and directory.<br />
<p>For example, if you installed Bitcoin in the default directory, mounted your Bitcoin encrypted drive as <code>E:\</code>, and stored your Bitcoin data directory on it as <code>Bitcoin</code>, you would type the following command as the shortcut Target:</p><br />
<blockquote><code>C:\Program Files\Bitcoin\bitcoin.exe -datadir=E:\Bitcoin</code></blockquote></li><br />
<li>Open Bitcoin's settings and configure it <b>NOT</b> to start automatically when you start Windows.<br />
<p>This is to allow you to mount the Bitcoin encrypted disk image before starting Bitcoin.</p></li><br />
<li>Shut down Bitcoin, and then restart it from the new shortcut.</li><br />
</ol><br />
<br />
After doing this, any time you want to use Bitcoin, you must first mount the Bitcoin encrypted disk image using the same drive designation, and then run Bitcoin from the shortcut that you created, so that it can find its data and your wallet.<br />
<br />
<br />
=== General Solutions ===<br />
<br />
Your wallet.dat file is not encrypted by the Bitcoin program by default but the most current release of the Bitcoin client provides a method to encrypt with a passphrase the private keys stored in the wallet. Anyone who can access an unencrypted wallet can easily steal all of your coins. Use one of these encryption programs if there is any chance someone might gain access to your wallet.<br />

<br />
There is also a list of [[OpenSourceEncryptionSoftware|open source encryption software.]]<br />
<br />
Decrypting and encrypting the wallet.dat every time you start or quit the Bitcoin client can be ''tedious'' (and outright error-prone). If you want to keep your wallet encrypted (except while you're actually running the Bitcoin client), it's better to relegate the automation to a [http://lorelei.kaverit.org/bitcoin.sh small shell script] that handles the en/decryption and starting up Bitcoin client for you (Linux and OSX). <br />
<br />
There is also a method to print out and encrypt your wallet.dat as a special, scannable code. See details here: [[WalletPaperbackup]]<br />
<br />
==== Password Strength ====<br />
Brute-force password cracking has come a long way. A password including capitals, numbers, and special characters with a length of 8 characters can be trivially solved now (using appropriate hardware). The recommended length is '''at least''' 12 characters long. You can also use a multi-word password and there are techniques to increase the strength of your passwords without sacrificing usability. [http://www.baekdal.com/tips/password-security-usability The Usability of Passwords] <br />
<br />
However, simply using dictionary words is also insecure as it opens you up to a dictionary attack. If you use dictionary words, be sure to include random symbols and numbers in the mix as well.<br />
<br />
If you use keyfiles in addition to a password, it is unlikely that your encrypted file can ever be cracked using brute-force methods, even when even a 12 character password might be too short.<br />
<br />
Assume that any encrypted files you store online (eg. Gmail, Dropbox) will be stored somewhere forever and can never be erased.<br />
<br />
===== Choosing A Strong Password =====<br />
Make sure you pick at least one character in each group:<br /><br />
<br />
Lowercase: abcdefghijklmnopqrstuvwxyz<br />
Uppercase: ABCDEFGHIJKLMNOPQRSTUVWXYZ<br />
Number: 1234567890<br />
Symbol: `~!@#$%^&*()-_=+\|[{]};:'",<.>/? (space)<br />
<br />
<9 char = unsuitable for use<br />
09 char = insecure<br />
10 char = low security<br />
11 char = medium security<br />
12 char = good security (good enough for your wallet)<br />
13 char = very good, enough for anything.<br />

== Backing up your wallet ==<br />
See [[Backingup_your_wallet|Backing up your wallet]].<br />
<br />
==Erasing Plain-text Wallets==<br />
<br />
In most operating systems, including Windows, Linux, and Mac OS X, simply deleting a wallet.dat file will ''not'' generally destroy it. It is likely that advanced tools can still be used to recover the wallet.dat file, even after it has been deleted.<br />
<br />
The Linux '''shred''' command can be used to overwrite the wallet file with random data prior to deleting; this particular copy of the file will then be practically impossible to recover. Using shred (and similar tools on Windows) however does not guarantee that still other copies don't exist somewhere hidden on your HD. That will depend on your system configuration and what packages you have installed. Some system restore and backup tools, for instance, create periodic snapshots of your filesystem, duplicating your wallet.dat.<br />
<br />
In Mac OS, the equivalent of '''shred''' is '''srm''' (introduced in Leopard). Using the Finder to remove files, clicking "Secure Empty Trash" in the Finder menu will shred the contents of the trash can. As with any OS this doesn't guarantee that there are not other copies elsewhere on your system.<br />
<br />
For Windows, the built-in command ''cipher /W'' will shred all previously-deleted files. [http://www.cylog.org/utilities/cybershredder.jsp CyberShredder] can securely deleted individual files.<br />
<br />
==Online and Mobile Wallets==<br />
<br />
Thus far, this article has been discussing the security of a wallet file for Bitcoin-QT or bitcoind that is under your sole control. Additional wallets applications and services have become available that offer other features and more convenience but not without introducing additional risk. When storing bitcoins with an [[eWallet]] such as Instawallet or Easywallet, you are essentially storing your private keys or wallet with that provider. <br />
<br />
Online wallets have a number of pros and cons to consider. For example, you can access your wallet on any computer in the world, but depending on the service, your bitcoins may be lost if the service is compromised. <br />
<br />
Mobile wallet applications are available for Android devices that allow you to send bitcoins by QR code or NFC, but this opens up the possibility of loss if mobile device is compromised. It may be possible to encrypt and backup the wallet or private keys on a mobile device but it is not advisable to store a large amount of bitcoins there without doing your own research and testing.<br />

<br />
==Paper Wallets==<br />
[[Paper wallet]]s can be used to store bitcoins offline in non-digital format. Using securely generated paper wallets significantly decreases the chances of your bitcoins being stolen by hackers or computer viruses.<br />
<br />
Fundamentally, a paper wallet is merely a physical record of a [[private key]] (most commonly written as a sequence of fifty-one alphanumeric characters beginning with a '5') and its corresponding [[public key]]. The private key is used to prove your right to spend the bitcoins transferred to the paper wallet, and as such should be kept hidden and secret. If the private key on a paper wallet is exposed (for example in a photograph) then the wallet may be "swept" by anyone who sees the key. To guard against accidental revelation, the private key displayed on the paper wallet may be encrypted using a password ("BIP38") or split into several different parts ("Shamir's secret sharing scheme"). 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 />
You can send bitcoins to the public address on your paper wallet as often as you like, and they will be inaccessible until the private key is imported into a "live" wallet. You can use a service such as blockchain.info to verify the balance of your paper wallet, which is a matter of public record. As of version 0.6.0, the bitcoin QT software has a command line feature called "importprivkey" that can load private keys. Online exchanges and wallets such as [[Coinbase (business)|Coinbase]] and [[Blockchain.info]] have features for importing (or "sweeping") paper wallet private keys as well.<br />
<br />
=== Software for generating paper wallets ===<br />
<br />
Some [[Paper wallet|paper wallet generators]] have been written entirely in HTML/JavaScript to make it fairly easy to generate paper wallets on virtually any operating system. Although these generators use a web browser, they are generally capable of running offline since address generation happens entirely within the web browser. It's advisable to use those services from [https://en.wikipedia.org/wiki/Live_CD live disc], to ensure that private keys are not compromised by spyware. <br />
<br />
To generate a safer paper wallet, first save the paper wallet generating code to a newly-formatted USB stick and verify the integrity (SHA1 hash or PGP signature) of the code. Then "clean-boot" your computer with a bootable CD (such as a Linux Live CD) while disconnected from the Internet. Insert the USB stick and open the wallet generator's HTML file using a web browser. Print your paper wallets or store them on external media (do not save them on the computer), and then shut down the computer. You may need to load an appropriate printer driver in order to print while booted from the live CD.<br />
<br />
=== Tips for making paper wallets ===<br />
<br />
* Disconnecting from the Internet guarantees that that the paper wallet generator is truly self-contained and isn't transmitting your keys online. <br />
<br />
* Verifying the integrity of the code (and the trustworthiness of the author) is important to make sure a hacker hasn't modified the HTML so that it generates predictable addresses instead of truly random keys.<br />
<br />
* Using a very basic printer is advisable since high-end office printers may have WiFi or internal storage that keeps a cache of printed documents.<br />
<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 and private keys 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 key can then be intercepted while you enter it, so only enter a Bitcoin private key into your computer when your intent is to redeem its value ''immediately''.<br />
<br />
== Hardware wallets ==<br />
[[Hardware wallet]]s are a major effort to provide a good combination of enhanced security and usability.<br />
<br />
So far only [http://www.pi-wallet.com/ Pi Wallet] is operational.<br />
<br />
==Importance of security updates==<br />
<br />
No software is perfect, and from time to time there may be security vulnerabilities found in your Bitcoin client as well.<br />
Be sure you keep your client updated with the latest bug fixes, especially when a new vulnerability is discovered.<br />
We maintain a [[CVEs|list a known vulnerabilities]] on this wiki - you can watch that page to get updates.<br />
Note that you ''don't'' need to be running the latest major client version: some clients, including the popular Bitcoin-Qt, have older versions available with bugfix-only updates.<br />
<br />
==Securing the Bitcoin-QT or bitcoind wallet==<br />
<br />
Bitcoin transactions send Bitcoins to a specific public key. A Bitcoin address is an encoded hash of a public key. In order to use received Bitcoins, you need to have the private key matching the public key you received with. This is sort of like a super long password associated with an account (the account is the public key). Your Bitcoin wallet contains all of the private keys necessary for spending your received transactions. If you delete your wallet without a backup, then you no longer have the authorization information necessary to claim your coins, and the coins associated with those keys are lost forever.<br />
<br />
The wallet contains a pool of queued keys. By default there are 100 keys in the [[key pool]]. The size of the pool is configurable using the "-keypool" command line argument. When you need an address for whatever reason (send, “new address”, generation, etc.), the key is not actually generated freshly, but taken from this pool. A brand new address is generated to fill the pool back to 100. So when a backup is first created, it has all of your old keys plus 100 unused keys. After sending a transaction, it has 99 unused keys. After a total of 100 new-key actions, you will start using keys that are not in your backup. Since the backup does not have the private keys necessary for authorizing spends of these coins, restoring from the old backup will cause you to lose Bitcoins.<br />
<br />
Creating a new address generates a new pair of public and private keys, which are added to your wallet. Each keypair is mostly random numbers, so they cannot be known prior to generation. If you backup your wallet and then create more than 100 new addresses, the keypair associated with the newest addresses will not be in the old wallet because the new keypairs are only known after creating them. Any coins received at these addresses will be lost if you restore from the backup.<br />
<br />
The situation is made somewhat more confusing because the receiving addresses shown in the UI are not the only keys in your wallet. Each Bitcoin generation is given a new public key, and, more importantly, each sent transaction also sends some number of Bitcoins back to yourself at a new key. When sending Bitcoins to anyone, you generate a new keypair for yourself and simultaneously send Bitcoins to your new public key and the actual recipient's public key. This is an anonymity feature – it makes tracking Bitcoin transactions much more difficult.<br />
<br />
So if you create a backup, do more than 100 things that cause a new key to be used, and then restore from the backup, some Bitcoins will be lost. Bitcoin has not deleted any keys (keys are never deleted) – it has created a new key that is not in your old backup and then sent Bitcoins to it.<br />
<br />
== Making a new wallet ==<br />
<br />
If a wallet or an encrypted wallet's password has been compromised, it is wise to create a new wallet and transfer the full balance of bitcoins to addresses contained only in the newly created wallet. Examples of ways a wallet may be compromised are through password re-use, minimal strength passwords, computer hack or virus attack.<br />
<br />
There are a number of ways to create a new wallet with Bitcoin-QT or bitcoind but this is a process that has been tested with bitcoind 0.6.3. We use the copy command to minimize the chance of any data loss but you are warned to make backups of any wallet.dat that holds a balance for you.<br />
<br />
:1. Shut down the Bitcoin program.<br />
:2. Find and make a backup of the "compromised" wallet.dat file and rename it, perhaps adding a short description:<br />
:::wallet.dat -> wallet-compromised.dat<br />
:Depending on your OS, the wallet file will be located at:<br />
:::Windows: %APPDATA%\Bitcoin\<br />
:::Linux: ~/.bitcoin/<br />
:::Mac: ~/Library/Application Support/Bitcoin/<br />
:3. Start the Bitcoin program and it will create a new wallet.dat. You may then encrypt the wallet as desired and make a new backup.<br />
:4. Once you've made a new wallet, you can obtain one or more addresses and copy them into a text editor. After obtaining the new address(es), shut down the Bitcoin program, make a backup of the new wallet.dat file and copy it to a new file named wallet-new.dat.<br />
:5. Copy the wallet-compromised.dat file back to wallet.dat, start the Bitcoin program and transfer your balance to the new address(es) you put in your text editor. Once the balance is back to 0 for your compromised wallet, you may want to wait a couple minutes or for a confirmation or check block explorer to be sure the transactions have been broadcasted. Then you may shut down the Bitcoin program.<br />
:6. Rename wallet.dat to wallet-compromised.dat. <br />
:7. Rename wallet-new.dat to wallet.dat.<br />
<br />
You should now have a new wallet with all the bitcoins from the old wallet.<br />
<br />
==Making a secure workspace==<br />
<br />
If you are using your computer to handle bitcoins, a wallet, Bitcoin-related passwords, or Bitcoin private keys, you must take care that the system is free of malware, viruses, keyloggers, remote access tools, and other tools that may be used to make remote copies of any of the above. In the case that your computer is compromised, the precautions taken below may provide additional protection.<br />
<br />
===Debian-based Linux===<br />
<br />
==== Store all into an encrypted folder (Tomb) ====<br />
<br />
Tomb is a simple tool to manage encrypted storage on GNU/Linux. Among its features are bind-hooks to set up a tomb's contents in the place where other programs expect them, for example in our case mount -o bind the .bitcoin directory in a user's home.<br />
<br />
First install tomb from https://files.dyne.org/tomb (homepage is on http://www.dyne.org/software/tomb)<br />
<br />
Among the requirements: zsh, cryptsetup, pinentry-curses, gnupg, sudo.<br />
<br />
Recommended: wipe, dcfldd, steghide, qrencode.<br />
<br />
Then create a tomb (we name it bitcoin) with three commands:<br />
<br />
<code>tomb dig -s 100 bitcoin.tomb</code><br />
<br />
<code>tomb forge bitcoin.tomb.key</code><br />
<br />
<code>tomb lock bitcoin.tomb -k bitcoin.tomb.key</code><br />
<br />
Then open it<br />
<br />
<code>tomb open bitcoin.tomb</code><br />
<br />
This will require you to input again the password you selected.<br />
<br />
Once open the tomb contents are in /media/bitcoin.tomb<br />
<br />
Move there your bitcoin wallet:<br />
<br />
<code>mv ~/.bitcoin /media/bitcoin.tomb/my-safe-wallet</code><br />
<br />
Then create a file "/media/bitcoin.tomb/bind-hooks" and put a single line:<br />
<br />
<code>my-safe-wallet .bitcoin</code><br />
<br />
Which means that every time the tomb is open, the directory my-safe-wallet needs to be bound to ~/.bitcoin. Just make sure an empty ~/.bitcoin directory exists in your home.<br />
<br />
Now close the tomb and store its keys safely, make sure you memorize the password. Have a look at Tomb's documentation, there is a number of things you can do like steganography or printing out keys on a paper to hide and such.<br />
<br />
That's it. Every time you like to access your wallet open the tomb and the .bitcoin will be in place. One can also store the bitcoin binary inside the tomb and even start the bitcoin client using the exec-hooks. Tomb's manual page "man tomb" explains the possibilities.<br />
<br />
The advantage of this approach over an encrypted home is that it becomes extremely portable across computers and even online shells: a Tomb is just a file and its key can be stored far away, on different shells, usb sticks or mobile phones.<br />
<br />
<br />
<br />
<br />
==== Secure the whole user home directory ====<br />
The first step is to make a [http://www.howtogeek.com/howto/ubuntu/add-a-user-on-ubuntu-server/ new user]. In order for that new user to have an encrypted home directory, you'll first need the encryption utility. Run:<br />
<br />
<code>sudo apt-get install ecryptfs-utils</code><br />
<br />
Now you're ready to create a new user<br />
<br />
<code>sudo adduser --encrypt-home new_user_name</code><br />
<br />
You'll need to come up with a [[#Choosing_A_Strong_Password|secure]] new password for that user.<br />
<br />
When you get to the prompt 'Enter the new value, or press ENTER for the default', just keep hitting ENTER.<br />
<br />
Then switch user to the new user. To get to the new user you can use the switch user icon for your system, which on Ubuntu is in the 'System/Quit' screen, or if there is no switch icon on your system you can log out and log back in as the new user.<br />
<br />
Since the home folder of this user is encrypted, if you're not logged in as that user, data that is saved there can't be browsed, even by a root user. If something goes wrong with your system, and you need to decrypt the new user's files, you'll need its decryption key.<br />
<br />
<code>ecryptfs-unwrap-passphrase</code><br />
<br />
It will ask you for your user's password and give you the decryption key. '''WRITE DOWN OR SAVE THE CODE IT RETURNS''' because you will need it if you ever have to pull your data off while the OS is not working. (You can run it again later if you need to, but run it now so that you can get your data if your Linux install gets botched.)<br />
<br />
The encrypted folder data is not encrypted while it's in memory, and so if it's ever sent to the swap partition it can be stolen from there unless that too is encrypted - be aware that this will mean you cannot use Hibernate anymore, as the bootloader won't be able to restore the hibernation data.<br />
<br />
<code>ecryptfs-setup-swap</code><br />
<br />
Then click on a folder in the new user to display the file browser, then keep going up folders until you see the new user home directory, then right click to bring up the Properties dialog, then click on the Permissions tab, then in the Others section, set the folder access to None.<br />
<br />
For secure browsing, open Firefox, and then go into the Edit menu and click Preferences. Starting from the left, click on the General tab, and in the 'Startup/When Firefox starts' pop up menu, choose 'Show a Blank Page'. Then click on the Content tab, and deselect 'Load images automatically' and deselect 'Enable JavaScript'. Then click on the Privacy tab, and in the 'History/Firefox will' pop up menu, choose 'Never remember history'. Then click on the Security tab, and in the Passwords section, deselect 'Remember passwords for sites' and deselect 'Use a master password'. Then click on the Advanced tab, then click on the Update tab, and then in the 'Automatically check for updates to' section, deselect 'Add-ons' and 'Search Engines'.<br />
<br />
When JavaScript is disabled, the [http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.3.23/bitcoin-0.3.23-linux.tar.gz/download Linux download page] will not download automatically, so you'll have to click on the 'direct link' part of the "Problems with the download? Please use this 'direct link' or try another mirror." line.<br />
<br />
===Mac===<br />
This solution '''does not scale'''; the amount of needed space can grow beyond the image size.<br />
<br />
===Windows===<br />
<br />
Due to the frequency with which Windows computers are compromised, it is advised to encrypt your wallet or to keep your wallet on an encrypted disk image created by third-party software, such as [http://www.truecrypt.org/ TrueCrypt] (open source) or [http://www.jetico.com/encryption-bestcrypt/ Jetico BestCrypt] (commercial). This also applies to the storage of passwords, private keys and other data that can be used to access any of your Bitcoin balances.<br />
<br />
Assuming that you have installed the Windows Bitcoin client and run it at least once, the process is described below.<br />
<br />
<p><b>To mount the Bitcoin data directory on an encrypted drive</b></p><br />
<ol start=1 type=1><br />
<li>Use the third-party disk image encryption program of your choice to create and mount an encrypted disk image of at least 5GB in size. This procedure stores the entire block chain database with the wallet.dat file so the required size of the encrypted disk image required may grow in the future.</li><br />
<li>Locate the Bitcoin data directory, and copy the directory with all contents to the encrypted drive.<br />
<p>For help finding this directory, see <b>[[Securing_your_wallet#Locating_Bitcoin_s_data_directory|Locating Bitcoin's Data Directory]]</b>.</p></li><br />
<li>Create a Windows shortcut that starts Bitcoin with the <code>-datadir</code> parameter and specifies the encrypted drive and directory.<br />
<p>For example, if you installed Bitcoin in the default directory, mounted your Bitcoin encrypted drive as <code>E:\</code>, and stored your Bitcoin data directory on it as <code>Bitcoin</code>, you would type the following command as the shortcut Target:</p><br />
<blockquote><code>C:\Program Files\Bitcoin\bitcoin.exe -datadir=E:\Bitcoin</code></blockquote></li><br />
<li>Open Bitcoin's settings and configure it <b>NOT</b> to start automatically when you start Windows.<br />
<p>This is to allow you to mount the Bitcoin encrypted disk image before starting Bitcoin.</p></li><br />
<li>Shut down Bitcoin, and then restart it from the new shortcut.</li><br />
</ol><br />
<br />
After doing this, any time you want to use Bitcoin, you must first mount the Bitcoin encrypted disk image using the same drive designation, and then run Bitcoin from the shortcut that you created, so that it can find its data and your wallet.<br />
<br />
<br />
=== General Solutions ===<br />
<br />
Your wallet.dat file is not encrypted by the Bitcoin program by default but the most current release of the Bitcoin client provides a method to encrypt with a passphrase the private keys stored in the wallet. Anyone who can access an unencrypted wallet can easily steal all of your coins. Use one of these encryption programs if there is any chance someone might gain access to your wallet.<br />

<br />
There is also a list of [[OpenSourceEncryptionSoftware|open source encryption software.]]<br />
<br />
Decrypting and encrypting the wallet.dat every time you start or quit the Bitcoin client can be ''tedious'' (and outright error-prone). If you want to keep your wallet encrypted (except while you're actually running the Bitcoin client), it's better to relegate the automation to a [http://lorelei.kaverit.org/bitcoin.sh small shell script] that handles the en/decryption and starting up Bitcoin client for you (Linux and OSX). <br />
<br />
There is also a method to print out and encrypt your wallet.dat as a special, scannable code. See details here: [[WalletPaperbackup]]<br />
<br />
==== Password Strength ====<br />
Brute-force password cracking has come a long way. A password including capitals, numbers, and special characters with a length of 8 characters can be trivially solved now (using appropriate hardware). The recommended length is '''at least''' 12 characters long. You can also use a multi-word password and there are techniques to increase the strength of your passwords without sacrificing usability. [http://www.baekdal.com/tips/password-security-usability The Usability of Passwords] <br />
<br />
However, simply using dictionary words is also insecure as it opens you up to a dictionary attack. If you use dictionary words, be sure to include random symbols and numbers in the mix as well.<br />
<br />
If you use keyfiles in addition to a password, it is unlikely that your encrypted file can ever be cracked using brute-force methods, even when even a 12 character password might be too short.<br />
<br />
Assume that any encrypted files you store online (eg. Gmail, Dropbox) will be stored somewhere forever and can never be erased.<br />
<br />
===== Choosing A Strong Password =====<br />
Make sure you pick at least one character in each group:<br /><br />
<br />
Lowercase: abcdefghijklmnopqrstuvwxyz<br />
Uppercase: ABCDEFGHIJKLMNOPQRSTUVWXYZ<br />
Number: 1234567890<br />
Symbol: `~!@#$%^&*()-_=+\|[{]};:'",<.>/? (space)<br />
<br />
<9 char = unsuitable for use<br />
09 char = insecure<br />
10 char = low security<br />
11 char = medium security<br />
12 char = good security (good enough for your wallet)<br />
13 char = very good, enough for anything.<br />

== Backing up your wallet ==<br />
See [[Backingup_your_wallet|Backing up your wallet]].<br />
<br />
==Erasing Plain-text Wallets==<br />
<br />
In most operating systems, including Windows, Linux, and Mac OS X, simply deleting a wallet.dat file will ''not'' generally destroy it. It is likely that advanced tools can still be used to recover the wallet.dat file, even after it has been deleted.<br />
<br />
The Linux '''shred''' command can be used to overwrite the wallet file with random data prior to deleting; this particular copy of the file will then be practically impossible to recover. Using shred (and similar tools on Windows) however does not guarantee that still other copies don't exist somewhere hidden on your HD. That will depend on your system configuration and what packages you have installed. Some system restore and backup tools, for instance, create periodic snapshots of your filesystem, duplicating your wallet.dat.<br />
<br />
In Mac OS, the equivalent of '''shred''' is '''srm''' (introduced in Leopard). Using the Finder to remove files, clicking "Secure Empty Trash" in the Finder menu will shred the contents of the trash can. As with any OS this doesn't guarantee that there are not other copies elsewhere on your system.<br />
<br />
For Windows, the built-in command ''cipher /W'' will shred all previously-deleted files. [http://www.cylog.org/utilities/cybershredder.jsp CyberShredder] can securely deleted individual files.<br />
<br />
==Online and Mobile Wallets==<br />
<br />
Thus far, this article has been discussing the security of a wallet file for Bitcoin-QT or bitcoind that is under your sole control. Additional wallets applications and services have become available that offer other features and more convenience but not without introducing additional risk. When storing bitcoins with an [[eWallet]] such as Instawallet or Easywallet, you are essentially storing your private keys or wallet with that provider. <br />
<br />
Online wallets have a number of pros and cons to consider. For example, you can access your wallet on any computer in the world, but depending on the service, your bitcoins may be lost if the service is compromised. <br />
<br />
Mobile wallet applications are available for Android devices that allow you to send bitcoins by QR code or NFC, but this opens up the possibility of loss if mobile device is compromised. It may be possible to encrypt and backup the wallet or private keys on a mobile device but it is not advisable to store a large amount of bitcoins there without doing your own research and testing.<br />

}}'''MtGox''', called "Mount Gox" or simply "Gox", was the most widely used bitcoin [[currency exchange]] market from 2010-2013<ref>2011-06-07 on #bitcoin-otc: "MagicalTux: you could use the count of users on mtgox (went over 30k recently)"</ref> since it was started. The market was closed February 25, 2014.<br />
<br />
A registrant on MtGox had at least two sub-accounts: one for bitcoins (BTC), and one for US dollars (USD or MTGUSD) or other national currency. Bitcoins were bought using funds from the trader's national currency account, and the proceeds from the sale of bitcoins were deposited into the same account. Trading always involved bitcoins as trading between different national currencies was not offered.<br />
<br />
Trades on Mt. Gox's executed from balances on deposit with the exchange which in turn made trading on the market instantaneous, compared to most other Bitcoin markets of the time where a subsequent settlement occurred manually between the trading partners. The disadvantage of this was that a third party had to be trusted with keeping the money safe.<br />
<br />
MtGox was originally started by Jed McCaleb in July 2010, and was sold to [[Tibanne Co.]] in Japan in March 2011. It was operated by Tibanne Co., managed by Mark Karpeles (MagicalTux).<br />
<br />
==Trading==<br />
===Buying and selling===<br />
<br />
A buy order was executed partially or in full when the price bid could be matched against a sell order that was at or below the bid amount. A sell order was executed partially or in full when the price asked could be matched against a buy order that was at or above the ask amount. Orders that could not be matched immediately remain in the orderbook.<br />
<br />
Unfunded orders did not appear in the order book, but were automatically inserted when a deposit was credited. For example, Mt. Gox allowed the entry of a "buy" order even if the account had insufficient funds. If possible, Mt. Gox would execute a portion of the order if it could be partially funded. If a deposit was later credited and the deposit resolves the insufficient funds status of an outstanding order, the order would be immediately activated, and if possible, executed.<br />
<br />
===Fees===<br />
<br />
Mt. Gox charged a trading fee of up to 0.6% from each party of successful trades made through the market. The fee appeared in the account history next to each trade. The trading fee was discounted for larger customers based on volume, which was calculated as a sliding window over the last 720 hours (30 days).<br />
<br />
The fees were, by default, subtracted from the proceeds of each trade (e.g., a buy of 1.0 BTC will add to the account balance 0.994 BTC when the exchange fee is 0.6%). An account setting would allow fees to be added to the purchase amount instead (e.g., buying 1.0 BTC at $5 will cost about $5.03 when the exchange fee is 0.6%).<br />
<br />
==Adding Funds==<br />
<br />
===BTC===<br />
There were no fees incurred when transferring bitcoins to a Mt. Gox account.<br />
<br />
Funds were available once [[confirmation|confirmed]] (6 blocks)<ref>[http://www.bitcoin.org/smf/index.php?topic=3851.msg55220#msg55220 How long does it take to Deposit bitcoins to MtGox?]</ref>, a process that could take roughly an hour.<br />
<br />
The deposit address was presented along with a QR code that can be scanned with a mobile. This address did not change with each deposit request.<br />
<br />
The Add Bitcoins function experienced issues with some browser ad-blocking utilities even though no advertisements were displayed on the website.<br />
<br />
====Redeemable Code====<br />
<br />
Bitcoins from another Mt. Gox user sent by Mt. Gox [[redeemable code]] (A.K.A. "coupon") could be deposited and would be available for trading.<br />
<br />
===OKPay===<br />
<br />
[[OKPay]] could be used for depositing funds to USD, EUR, GBP, CHF, and RUB<ref>[https://support.mtgox.com/entries/21034626-okpay OKPAY]</ref>.<br />
<br />
===Cash Deposit===<br />
<br />
====U.S. (USD)====<br />
* BitInstant - Cash (U.S. dollars) could be deposited at any of thousands of banks, 7-11, Walmart, CVS, Moneygram and more that [[BitInstant]] uses to transfer funds to your Mt. Gox account.<br />
<br />
====Brazil (BRL)====<br />
* BitInstant - Cash (Brazilian real) could be deposited using Boleto or through Banco Recomendito.<br />
<br />
====Brazil (BRL)====<br />
* BitInstant - Cash (Russian rubles) could be deposited using QIWI or Cyberplat<br />
<br />
====UK (GBP)====<br />
* Barclays - Cash (British pound sterling) could be deposited at any Barclays location. There was a 1.5% fee on deposits made with this method<ref>[https://mtgox.com/press_release_20120806.html Introducing a new 1.5% fee on Barclays cash deposit]</ref>.<br />
<br />
===Bank Wire===<br />
<br />
====International USD====<br />
Funds in USD could be wired to the exchange's bank in Japan. Each wire is subject to a per-wire fee plus any intermediate fees. <br />
<br />
====International Wire====<br />
<br />
An account can be configured with a wallet for each of the currencies that the exchange supports<ref>[https://mtgox.zendesk.com/entries/20413328-mt-gox-opens-15-new-currency-markets Mt.Gox Opens 15 New Currency Markets]</ref>. When a wire is received in one of these currencies, that account will be credited.<br />
<br />
* USD - U.S. Dollar <br />
* EUR - Euro (SEPA or Int'l wire)<br />
* CAD - Canadian Dollar<br />
* GBP - British Pound (Domestic or Int'l wire)<br />
* CHF - Swiss Francs<br />
* RUB - Russian Rubles<br />
* AUD - Australian Dollars<br />
* SEK - Swedish Krona<br />
* DKK - Danish Krona<br />
* HKD - Hong Kong Dollars<br />
* PLN - Polish Zloty (Domestic or Int'l wire)<br />
* CNY - Chinese Yuan<br />
* SGD - Singapore Dollars<br />
* TBH - Thai Baht<br />
* NZD - New Zealand Dollars<br />
* JPY - Japanese Yen (Domestic or Int'l wire)<br />
<br />
===Direct Deposit===<br />
====EU====<br />
<br />
Funds in EUR could be added using SEPA Direct Debit for free, with funds convert to USD at the current ECB rate at the time the funds were received<ref>[http://www.bitcoin.org/smf/index.php?topic=5461.0 MTGox: Euro deposits]</ref>.<br />
<br />
====U.S.====<br />
<br />
Mt. Gox doesn't directly support an ACH-based (direct deposit) deposit method. Dwolla supports ACH-based fund transfers and those funds can then be deposited with Mt. Gox.<br />
<br />
====UK====<br />
<br />
Funds could be sent as a GBP direct deposit free of charge.<br />
<br />
====Australia====<br />
<br />
Funds could be sent using direct deposit (BPay) for a AU$2.00 per-deposit fee. The funds will be converted to USD at the current rate.<br />
<br />
==Withdrawing Funds==<br />
<br />
MtGox imposes a $1,000 USD limit for withdrawals per 24 hours and a $10,000 USD limit for withdrawals per month with most non-verified accounts. Bitcoins withdrawn were counted toward this limit as well and the USD value was calculated at the market rate at the time of the attempted withdrawal. Customers that have been Verified have higher limits and customers that have Trusted status have limits even higher<ref>[http://bitcoin.stackexchange.com/questions/2442/mtgox-trusted-vs-verified MtGox - trusted vs verified]</ref>. Any [[MtGox#Transfers_to_Other_Customers|account-to-account transfers]] made also count toward this limit as well.<br />
<br />
Requests for higher withdrawal limits could be submitted by email<br />
* For higher limits for withdrawal of USD funds, email: aml@mtgox.com<br />
* For higher limits for withdrawal of BTC funds, email: btcupd@mtgox.com<br />
<br />
See the [[MtGox#AML|AML]] section regarding verification levels for AML purposes.<br />
<br />
===Dwolla===<br />
<br />
[[Dwolla]] was among the fastest and least expensive methods for withdrawing USD funds from a Mt. Gox account. The transaction fee to do so was just $0.25.<br />
[[Dwolla]] withdrawals were processed every hour during business hours (Japan time) and every 12 hours on weekends.<br />
<br />
As of 25 May 2012, MtGox requires account holders to be "verified (level 1) - 'see below'" to withdraw via Dwolla. <ref>https://support.mtgox.com/entries/21503347-new-aml-policy-for-all-dwolla-users</ref><br />
<br />
The status of the withdrawal request will show one of the following status codes:<br />
<br />
* Preparing: System was running checks to see if the transfer can be executed.<br />
* Confirmed: Transfer could be executed and was pending in queue.<br />
* Todo: Transfer was near the top of the queue and will be executed soon.<br />
* Processed: Transfer has been processed.<br />
<br />
===BTC===<br />
<br />
Bitcoins could be withdrawn at no charge.<br />
<br />
A [[green address]] option was available though this type of transaction could experience a delay if the exchange's wallet funding level for green address transactions was insufficient. The withdrawal form also offers an "open transaction" option which forces the transaction to go through the blockchain. If the recipient of a BTC withdrawal happens to also be from Mt. Gox's [[EWallet]], then that transfer would occur instantly and the transaction would not be broadcast to the Bitcoin network. This "open transaction" option forces a withdrawal to be broadcast to the Bitcoin network.<br />
<br />
====Redeemable Code====<br />
<br />
Mt. Gox no longer allows bitcoins or other currency to be withdrawn using a [[redeemable code]].<br />
<br />
===Direct Deposit===<br />
====U.S.====<br />
<br />
There was currently no option for withdrawing funds through a direct deposit bank transaction. Funds withdrawn to Dwolla could then, in turn, be withdrawn with bank funds deposited as an ACH transaction.<br />
<br />
====EU====<br />
<br />
Users could withdraw any amount as a direct deposit to their bank. There was a 2% fee on these withdrawals. Contact the exchange by e-mail for this service.<br />
<br />
====Australia====<br />
<br />
A per-withdrawal fee (2,000 JPY) was subtracted and the remaining amount was sent via international wire in the chosen currency. If not AUD then an exchange fee of 2.5% would be charged.<br />
<br />
===International Wire===<br />
<br />
To any IBAN, SWIFT/BIC and ABA routable bank<ref>[http://www.facebook.com/MtGox/posts/343372689080478 Mt.Gox now offers international wire transfer to all US Banks]</ref>. Fee applies.<br />
<br />
=<br />
<br />
==Customer Service==<br />
<br />
The preferred method for obtaining service was to place a request through the exchange's [https://mtgox.zendesk.com help desk]. Another method was to send e-mail with the request.<br />
<br />
==Wallet/Banking==<br />
<br />
An account at this exchange can be considered to be an [[eWallet]]. This service also offers [[:Category:ECommerce|eCommerce]] merchant [https://mtgox.com/merch/about payment services].<br />
<br />
==Security Center==<br />
<br />
The Security Center allows an account to be secured through the use of one or more One Time Password (OTP) solutions such as what YubiKey and Google Authenticator offer. Features can be protected where the OTP must be provided for each action and were configured independently.<br />
<br />
For example, a typical configuration was to set OTP as being required for both withdrawals and security center changes but not for login. With that configuration, the worst damage that can happen from a compromised account or session would be that bitcoins would be bought or sold (though they could also be bought and sold over and over until funds were depleted).<br />
<br />
* Login - The OTP must be provided for each login.<br />
* Withdraw - The OTP must be provided for each withdrawal request.<br />
* Security - The OTP must be provided during each configuration change to be performed.<br />
<br />
==AML==<br />
<br />
Varying degrees of verification will allow for greater per-day and per-month total amounts to be withdrawn<ref>[http://support.mtgox.com/entries/20919111-aml-account-statuses AML Account Statuses]</ref>.<br />
<br />
===Unverified (Level 0)===<br />
<br />
Designed for basic users, consumers and Bitcoin enthusiasts where 10,000 USD (monthly) was enough for most needs.<br />
<br />
===Verified (Level 1)===<br />
<br />
The "verified" status was designed for active traders and/or small companies.<br />
<br />
===Trusted (Level 2)===<br />
<br />
The “trusted” status was designed for day traders, professionals, and companies.<br />
<br />
==API==<br />
<br />
Mt Gox offers an [[MtGox/API|API]] which can be used to automate operations.<br />

==E-Commerce==<br />
<br />
Online sellers could accept bitcoins for payment using the Mt. Gox's E-commerce Solution, which was an interface to the exchange's [[MtGox/API/HTTP/v1#Merchant_System|Merchant System API]].<br />
<br />
==History==<br />
The exchange went online on July 18, 2010.<ref>[http://www.bitcoin.org/smf/index.php?topic=444.0 MtGox announcement on forum]</ref><br />
<br />
On October 10, 2010 the exchange switched from [[PayPal]] to Liberty Reserve as the main funding option as a result of this attack. Former PayPal customers still had the possibility to withdraw their USD using alternative methods.<br />
<br />
On March 6th, 2011 ownership of the exchange changed hands<ref>[https://bitcointalk.org/index.php?topic=4187.0 Mtgox is changing owners]</ref>. Tibanne publishes their [http://legal.tibanne.com/docs/20110801_company_certificate.pdf company certificate] from the Japanese government.<br />
<br />
On June 19, 2011 the service experienced a significant security breach<ref>[https://support.mtgox.com/entries/20224998-huge-bitcoin-sell-off-due-to-a-compromised-account-rollback Huge Bitcoin sell off due to a compromised account - rollback]</ref>. The incident caused a selloff down to BTC/USD of $0.01 due to fraudulent trading. The site was disabled and all trading following the point that fraudulent trading began was rolled back. Complicating this breach was the release of a list of the exchange's accounts including username, email address and a password hash, which forced the exchange to implement an account recovery method for customers to regain control of their accounts.<br />
<br />
In July, 2011 it was observed that the exchange no longer allows new registrations to occur without having a valid e-mail address.<br />
<br />
On July 19, 2011 a press release announced that MtGox had acquired [[MtGox Live]].<ref>[https://mtgox.com/press_release_20110719.html World's Leading Bitcoin Exchange, Mt.Gox, acquires MtGoxLive.com]</ref><br />

<div>== What is Litecoin? ==<br />
Litecoin is an alternative cryptocurrency based on Bitcoin. It differs from Bitcoin in that it targets a faster block rate (2.5 minutes) and uses scrypt for the primary hashing done in mining.<br />
<br />
While scrypt was claimed to be resistant to GPU-based mining early on, GPUs are currently the most efficient hardware with which to mine Litecoins.<br />
One of the aims of Litecoin was to provide a mining algorithm that did not compete with Bitcoin.<br />
<br />
In April 2014, Litecoin reached a market cap of $270 million and achieved a network strength above 100 gigahashes/second. This compares roughly to a network strength for Bitcoin of 100 terahashes/second.<br />
<br />
== Differences from Bitcoin ==<br />
<br />
==== Scrypt Proof of Work ====<br />
Litecoin uses scrypt as a proof-of-work scheme. Scrypt adds memory-intensive algorithms to reduce the efficiency of the kind of parallelization that GPUs offered in early Bitcoin mining. This led to Litecoin primarily being mined with CPUs at the beginning. CPU-based mining has been challenged by the appearance of more energy-efficient GPU-based mining around July/August of 2012 bringing a roughly ten-fold increase in network hashing strength. GPUs are currently the dominant Litecoin mining technology.<br />
<br />
Scrypt has been less widely used and analyzed than the SHA2 hashing algorithm used in Bitcoin, so there is some concern about possible weaknesses in its cryptographic scheme being discovered in the future.<br />
<br />
==== Faster Blocks ====<br />
The Litecoin blockchain differs from Bitcoin in that it generates blocks every 2.5 minutes on average (four times Bitcoin's rate).<br />
This means that merchants who accept transactions only 1 block deep get that confirmation quicker.<br />
However, it should be noted that more blocks are required to achieve the same amount of confirmation strength as Bitcoin (6 blocks of litecoin are not equivalent to 6 blocks of bitcoin).<br />
Unfortunately, this increases the number of hashes that are wasted in mining since miners will be working from the non-best block more of the time.<br />
<br />
==== 84 Million Litecoins ====<br />
Litecoin started with miners generating 50 coins per block as with Bitcoin, but to maintain Bitcoin's inflation rate chage schedule, the block reward gets halved every 840,000 blocks. As a result, the network is scheduled to produce a total of 84 million litecoins.<br />
<br />
==== Different Addresses ====<br />
<br />
Litecoin addresses start with L due to their version number. Otherwise, they are generated identically to Bitcoin addresses.<br />
<br />
==== (Slight) Premining ====<br />
Litecoin had two blocks premined, one more than the minimum single genesis block needed to start a block chain.<br />
<br />
==Criticism==<br />
==== Redundancy ====<br />
<!-- NOTE: scrypt is not a feature, since it is a flaw --><br />
Besides a faster first confirmation, Litecoin does not provide any other features over what Bitcoin provides.<br />
Because of this lack of innovation, some believe Litecoin is unlikely to match or surpass Bitcoin's value or user-base.<br />
It remains to be seen if the use of a different mining algorithm and faster block times add sufficient value for Litecoin's long-term survival.<br />
<br />
==== Not Silver to Gold ====<br />
Some argue that Litecoin cannot make sense as "silver to bitcoin's gold", because Bitcoin itself is both gold and silver:<br />
While in the long-run, the BTC unit may be too valuable for everyday trade ("gold"), there are other, much smaller [[units]] that can just as well serve the purpose of "silver" while being naturally/automatically "converted" to/from BTC.<br />
<br />
==== Vulnerability to mining monopoly ====<br />
<br />
Similarly to Bitcoin, Litecoin can be attacked by an entity that can match or exceed the hashrate of the network. Such a "51% attack" becomes more difficult to launch and maintain as the hash rate of the network grows. However, this argument posits that Litecoin is designed to be inefficient on all common computer components (both CPUs and GPUs) meaning that a malicious entity need only produce a small batch of specialized/custom hardware to overtake all the commodity mining systems combined.<br />
<br />
===== Memory bandwidth refutation =====<br />
Some attempt to refute this by arguing that scrypt is not designed to be inefficient, but is instead designed to be highly dependent on memory bandwidth.<br />
Since the high-speed cache RAM on modern processors already takes up most of the die space, no sizeable improvement could then be made by creating custom chips.<br />
If we accept this argument we then estimate the cost of attack utilizing GPUs that are avilable today. <br />
<br />
To do so we start with an estimated cost of hardware at $400 per megahashes per second and the October 2013 Litecoin network hashrate of 30 gigahashes per second.<br />
The total amount of equipment necessary to match and takeover the Litecoin network via 51% attack is then an estimated $12M USD (or about 45,000 AMD HD 7950s).<br />
<br />
==== Pump and Dump Scheme ====<br />
According to some, one or more of the aforementioned reasons imply that Litecoin has no future potential, and therefore effectively functions as a [http://www.investopedia.com/terms/p/pumpanddump.asp "pump and dump" scheme], rewarding those who get in sooner at the expense of those who adopt it just before it finally fails (and are left with nothing).<br />
<br />
Additionally, people often complain that the Litecoin community misrepresents it in other ways, such as portraying "faster block times" as if it makes transactions faster, and scrypt as if it is resistant to ASIC or FPGA hardware, in order to pretend Litecoin has value and inflate its value.<br />
<br />
It's important to note, generally these critics do not think that Litecoin/Blockchain currencies are pump and dump schemes "per se"; but rather that the existing network effect of Bitcoin, combined with the lack of meaningful differentiation between Litecoin and Bitcoin and Litecoin's adoption of a "designed to fail" proof-of-work algorithm; that Litecoin is bound to fail in the end. Bitcoin does not suffer from these "flaws" and therefore does not fall under the "pump and dump" scheme, according to this argument.<br />

<br />
[http://bitcoin.stackexchange.com/questions/2293/how-can-i-buy-bitcoin-via-a-credit-card-or-paypal You can't directly buy Bitcoins using PayPal], because it is risky for the seller, and therefore few sellers will offer this. There are basically 3 reasons for that:<br />
<br />
* The buyer of bitcoins can always perform a chargeback and there is no way for the seller to contest that<br />
<br />
* There are many hacked accounts and when PayPal realizes that such an account has been fraudulently used, they will also perform a chargeback<br />
<br />
* PayPal doesn't like bitcoin, as the bitcoin network is in direct competition to it. They will ban accounts that have anything to do with Bitcoins, and freeze their balance.<br />
<br />
Having said that there is a [http://99bitcoins.com/buying-bitcoins-with-paypal-a-practical-guide/ workaround] that can be done in order to use Paypal to buy Bitcoins but it holds within it higher transaction fees. Using the [http://VirrWox.com Virtual World Exchange] you can buy Second Life Lindens (SLL) with Paypal and then convert your SLL to Bitcoins. This process will charge you transaction fees of around 6% but will let you purchase Bitcoins pretty quickly as opposed to a wire transfer. The reason this method works is because you do not buy Bitcoins with Paypal directly, you only buy SLL with Paypal (which is acceptable by Paypal's TOS) and then exchange your SLL to Bitcoin.<br />
<br />
'''Note:''' If you only want to take advantage of Bitcoin's price volatility You can trade CFDs on Bitcoin via Paypal on sites like [http://Ava-Trade.co.uk AvaTrade] or [http://99bitcoins.com/plus500 Plus500].

=== Anonymity ===<br />
There is a HUGE demand for buying Bitcoins off the grid due to ever-increasing government regulations and private agency intrusions and discrimination against alternative currencies. <br />
Due to the possibility of facial recognition cameras at banks and the paper trail involved with credit cards, there are very few options to have high levels of anonymity when buying Bitcoins those ways. DNA, Fingerprints, phone and internet records, audio and video records will not be discussed, but they all are possible tools which attackers could use to uncloak even the stealthiest Bitcoin buyer.<br />
There are a couple known ways, depending on your location, to buy Bitcoins outside of the standard banking system with relatively high anonymity.<br />
Buying locally with cash using a burner or payphone allows a high level of anonymity with the exchange being the weakest link.<br />
Many sellers online will also trade Bitcoins for [[MoneyPak]] codes or other cash-like gift codes which can be bought at a local store with cash.<br />
Another way to buy Bitcoins with a high level of anonymity is by sending cash in the mail.<br />

=== What is "difficulty"? ===<br />
<br />
Difficulty is a measure of how difficult it is to find a new [[block]] compared to the easiest it can ever be.<br />
<br />
=== How often does the difficulty change? ===<br />
<br />
Every 2016 [[block|blocks]].<br />
<br />
=== What is the formula for difficulty? ===<br />
<br />
difficulty = maximum_target / current_target <br />
<br />
(target is a 256 bit number)<br />
<br />
===How is difficulty stored in blocks?===<br />
<br />
Each block stores a packed representation (called "Bits") for its actual hexadecimal [[target]]. The target can be derived from it via a predefined formula. For example, if the packed target in the block is 0x1b0404cb, the hexadecimal target is<br />
0x0404cb * 2**(8*(0x1b - 3)) = 0x00000000000404CB000000000000000000000000000000000000000000000000<br />

Note that the 0x0404cb value is a signed value in this format. The largest legal value for this field is 0x7fffff. To make a larger value you must shift it down one full byte. Also 0x008000 is the smallest positive valid value.<br />
<br />
The highest possible target (difficulty 1) is defined as 0x1d00ffff, which gives us a hex target of<br />
0x00ffff * 2**(8*(0x1d - 3)) = 0x00000000FFFF0000000000000000000000000000000000000000000000000000<br />
<br />
It should be noted that pooled mining often uses non-truncated targets, which puts "pool difficulty 1" at<br />
0x00000000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF<br />
<br />
So the difficulty at 0x1b0404cb is therefore:<br />
0x00000000FFFF0000000000000000000000000000000000000000000000000000 /<br />
0x00000000000404CB000000000000000000000000000000000000000000000000 <br />
= 16307.420938523983 (bdiff)<br />
And:<br />
0x00000000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF /<br />
0x00000000000404CB000000000000000000000000000000000000000000000000 <br />
= 16307.669773817162 (pdiff)<br />
<br />
Here's a fast way to calculate bitcoin difficulty. It uses a modified Taylor series for the logarithm (you can see tutorials on flipcode and wikipedia) and relies on logs to transform the difficulty calculation:<br />
<br />
<source lang="cpp"><br />
#include <iostream><br />
#include <cmath><br />
<br />
inline float fast_log(float val)<br />
{<br />
int * const exp_ptr = reinterpret_cast <int *>(&val);<br />
int x = *exp_ptr;<br />
const int log_2 = ((x >> 23) & 255) - 128;<br />
x &= ~(255 << 23);<br />
x += 127 << 23;<br />
*exp_ptr = x;<br />
<br />
val = ((-1.0f/3) * val + 2) * val - 2.0f/3;<br />
return ((val + log_2) * 0.69314718f);<br />
} <br />
<br />
float difficulty(unsigned int bits)<br />
{<br />
static double max_body = fast_log(0x00ffff), scaland = fast_log(256);<br />
return exp(max_body - fast_log(bits & 0x00ffffff) + scaland * (0x1d - ((bits & 0xff000000) >> 24)));<br />
}<br />
<br />
int main()<br />
{<br />
std::cout << difficulty(0x1b0404cb) << std::endl;<br />
return 0;<br />
}<br />
</source><br />
<br />
Unfortunately I don't have much use for it in libbitcoin. Maybe some miner will find it useful.<br />
<br />
To see the math to go from the normal difficulty calculations (which require large big ints bigger than the space in any normal integer) to the calculation above, here's some python:<br />
<br />
<source lang="python"><br />
import decimal, math<br />
l = math.log<br />
e = math.e<br />
<br />
print 0x00ffff * 2**(8*(0x1d - 3)) / float(0x0404cb * 2**(8*(0x1b - 3)))<br />
print l(0x00ffff * 2**(8*(0x1d - 3)) / float(0x0404cb * 2**(8*(0x1b - 3))))<br />
print l(0x00ffff * 2**(8*(0x1d - 3))) - l(0x0404cb * 2**(8*(0x1b - 3)))<br />
print l(0x00ffff) + l(2**(8*(0x1d - 3))) - l(0x0404cb) - l(2**(8*(0x1b - 3)))<br />
print l(0x00ffff) + (8*(0x1d - 3))*l(2) - l(0x0404cb) - (8*(0x1b - 3))*l(2)<br />
print l(0x00ffff / float(0x0404cb)) + (8*(0x1d - 3))*l(2) - (8*(0x1b - 3))*l(2)<br />
print l(0x00ffff / float(0x0404cb)) + (0x1d - 0x1b)*l(2**8)<br />

=== What is the current difficulty? ===<br />
[http://blockexplorer.com/q/getdifficulty Current difficulty], as output by BitCoin's getDifficulty.<br />
<br />
[http://blockexplorer.com/q/estimate Estimated next difficulty]<br />
<br />
[http://bitcoin.sipa.be Graphs]<br />
<br />
=== What is the maximum difficulty? ===<br />
<br />
There is no minimum target. The maximum difficulty is roughly: maximum_target / 1 (since 0 would result in infinity), which is a ridiculously huge number (about 2^224). <br />
<br />
The actual maximum difficulty is when current_target=0, but we would not be able to calculate the difficulty if that happened. (fortunately it never will, so we're ok.)<br />
<br />
=== Can the difficulty go down? ===<br />
Yes it can. See discussion in [[target]].<br />
<br />
=== What is the minimum difficulty? ===<br />
The minimum difficulty, when the target is at the maximum allowed value, is 1.<br />
<br />
=== What network hash rate results in a given difficulty? ===<br />
The difficulty is adjusted every 2016 blocks based on the time it took to find the previous 2016 blocks. At the desired rate of one block each 10 minutes, 2016 blocks would take exactly two weeks to find. If the previous 2016 blocks took more than two weeks to find, the difficulty is reduced. If they took less than two weeks, the difficulty is increased. The change in difficulty is in proportion to the amount of time over or under two weeks the previous 2016 blocks took to find.<br />
<br />
To find a block, the hash must be less than the target. The hash is effectively a random number between 0 and 2**256-1. The offset for difficulty 1 is<br />
0xffff * 2**208<br />
and for difficulty D is<br />
(0xffff * 2**208)/D<br />
<br />
The expected number of hashes we need to calculate to find a block with difficulty D is therefore<br />
D * 2**256 / (0xffff * 2**208)<br />
or just<br />
D * 2**48 / 0xffff<br />
<br />
The difficulty is set such that the previous 2016 blocks would have been found at the rate of one every 10 minutes, so we were calculating (D * 2**48 / 0xffff) hashes in 600 seconds. That means the hash rate of the network was<br />
D * 2**48 / 0xffff / 600<br />
over the previous 2016 blocks. Can be further simplified to<br />
D * 2**32 / 600<br />
without much loss of accuracy.<br />
<br />
At difficulty 1, that is around 7 Mhashes per second.<br />
<br />
At the time of writing, the difficulty is 22012.4941572, which means that over the previous set of 2016 blocks found the average network hash rate was<br />
22012.4941572 * 2**32 / 600 = around 157 Ghashes per second.<br />
<br />
=== How soon might I expect to generate a block? ===<br />
(The [https://www.bitcointalk.org/index.php?topic=1682.0 eternal question].)<br />
<br />
The average time to find a block can be approximated by calculating:<br />
time = difficulty * 2**32 / hashrate<br />
where difficulty is the current difficulty, hashrate is the number of hashes your miner calculates per second, and time is the average in seconds between the blocks you find.<br />
<br />
For example, using Python we calculate the average time to generate a block using a 1Ghash/s mining rig when the difficulty is 20000:<br />
$ python -c "print 20000 * 2**32 / 10**9 / 60 / 60.0"<br />
23.85<br />
and find that it takes just under 24 hours on average.<br />
<br />
* Any one grinding of the hash stands the same chance of "winning" as any other. The numbers game is how many attempts your hardware can make per second.<br />
* You need to know the difficulty (above) and your khash/sec rate (reported by the client).<br />
** [[Mining Hardware Comparison]] has some stats that may help you predict what you could get.<br />
* Visit a calculator or perform the maths yourself,<br />

* Remember it's just probability! There are no guarantees you will win every N days.<br />
