Vv01f: adding link

This page is an index of projects using Taproot in an interesting way. Please update with links.
Also see [[Bech32 adoption]] for Wallets implementing Bech32m and P2TR.

Phases Key:

* Implemented: Real running code without major known deficiencies.
* Spec: A detailed document describing how something should work.
* Prototype: A component of something is built or a toy-level implementation.
* Idea: A description of something which could be built.

Bech32 adoption

2021-11-17T14:10:35Z

Vv01f: /* Software Wallets */

[[Bech32]] is a bitcoin [[address]] format specified by [[BIP 0173]]. It is used for the native segwit version 0 output types, P2WPKH and P2WSH. The upcoming [[Taproot]] softfork will add another output type called Pay to Taproot (P2TR). P2TR outputs and future native segwit versions will be using an updated variant of [[Bech32]], called [[Bech32m]] (specified by [[BIP 0350]]). This page tracks the adoption of [[Bech32]] and [[Bech32m]].

Ideally wallets and services would first support ''sending to'' new addresses. When most wallets and services support sending to the new address type, people are more likely to adopt it for receiving.

The amount of bech32 addresses on the blockchain is tracked on this website: https://p2sh.info/dashboard/db/bech32-statistics?orgId=1

=== Hardware Wallets ===

Hardware wallet manufacturers typically publish a web wallet or browser add-on wallet for use with their hardware. Users can also sometimes connect their hardware wallet to a software wallet like [[Electrum]].

=== Blockchain Explorers ===

To investigate bech32 capability, you can use mainnet TXIDs <code>4ef47f6eb681d5d9fa2f7e16336cd629303c635e8da51e425b76088be9c8744c</code> and <code>514a33f1d46179b89e1fea7bbb07b682ab14083a276979f91038369d1a8d689b</code> or look up the addresses <code>bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq</code> and <code>bc1qc7slrfxkknqcq2jevvvkdgvrt8080852dfjewde450xdlk4ugp7szw5tk9</code>.

Some blockchain explorers can only parse the bech32 address and display it, they don't build an index so users cannot search for bech32 addresses.

To verify bech32m readiness, you can look up the mainnet TXID <code>b10c007c60e14f9d087e0291d4d0c7869697c6681d979c6639dbd960792b4d41</code> on which the first output should be addressed as <code>bc1pqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqsyjer9e</code>. Note that the superseded bech32 encoding only differs in the last six characters that encode the checksum: <code>bc1pqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqs_3wf0qm_</code>.

Bech32 adoption

2021-11-17T14:08:46Z

Vv01f: adding Wallet of Satoshi, sort

[[Bech32]] is a bitcoin [[address]] format specified by [[BIP 0173]]. It is used for the native segwit version 0 output types, P2WPKH and P2WSH. The upcoming [[Taproot]] softfork will add another output type called Pay to Taproot (P2TR). P2TR outputs and future native segwit versions will be using an updated variant of [[Bech32]], called [[Bech32m]] (specified by [[BIP 0350]]). This page tracks the adoption of [[Bech32]] and [[Bech32m]].

Ideally wallets and services would first support ''sending to'' new addresses. When most wallets and services support sending to the new address type, people are more likely to adopt it for receiving.

The amount of bech32 addresses on the blockchain is tracked on this website: https://p2sh.info/dashboard/db/bech32-statistics?orgId=1

=== Hardware Wallets ===

Hardware wallet manufacturers typically publish a web wallet or browser add-on wallet for use with their hardware. Users can also sometimes connect their hardware wallet to a software wallet like [[Electrum]].

To investigate bech32 capability, you can use mainnet TXIDs <code>4ef47f6eb681d5d9fa2f7e16336cd629303c635e8da51e425b76088be9c8744c</code> and <code>514a33f1d46179b89e1fea7bbb07b682ab14083a276979f91038369d1a8d689b</code> or look up the addresses <code>bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq</code> and <code>bc1qc7slrfxkknqcq2jevvvkdgvrt8080852dfjewde450xdlk4ugp7szw5tk9</code>.

Some blockchain explorers can only parse the bech32 address and display it, they don't build an index so users cannot search for bech32 addresses.

To verify bech32m readiness, you can look up the mainnet TXID <code>b10c007c60e14f9d087e0291d4d0c7869697c6681d979c6639dbd960792b4d41</code> on which the first output should be addressed as <code>bc1pqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqsyjer9e</code>. Note that the superseded bech32 encoding only differs in the last six characters that encode the checksum: <code>bc1pqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqszqgpqyqs_3wf0qm_</code>.

Bech32 adoption

2019-11-28T11:12:37Z

Vv01f: /* Exchanges */

[[Bech32]] is a new bitcoin [[address]] format specified by [[BIP 0173]]. This page tracks the adoption of [[Bech32]].

Ideally wallets and services would first support ''sending to'' bech32 addresses. After almost everything can send to, then people may be willing to adopt bech32 widely for receiving.

The amount of bech32 addresses on the blockchain is tracked on this website: https://p2sh.info/dashboard/db/bech32-statistics?orgId=1

BIP 0016

2012-11-22T08:37:44Z

Vv01f:

{{bip}}

<pre>
BIP: 16
Title: Pay to Script Hash
Author: Gavin Andresen <gavinandresen@gmail.com>
Status: implemented and alive on the network
Type: Standards Track
Created: 03-01-2012
</pre>

==Abstract==

This BIP describes a new "standard" transaction type for the Bitcoin scripting system, and defines additional validation rules that apply only to the new transactions.

==Motivation==

The purpose of pay-to-script-hash is to move the responsibility for supplying the conditions to redeem a transaction from the sender of the funds to the redeemer.

The benefit is allowing a sender to fund any arbitrary transaction, no matter how complicated, using a fixed-length 20-byte hash that is short enough to scan from a QR code or easily copied and pasted.

==Specification==

A new standard transaction type that is relayed and included in mined blocks is defined:

OP_HASH160 [20-byte-hash-value] OP_EQUAL

[20-byte-hash-value] shall be the push-20-bytes-onto-the-stack opcode (0x14) followed by exactly 20 bytes.

This new transaction type is redeemed by a standard scriptSig:

...signatures... {serialized script}

Transactions that redeem these pay-to-script outpoints are only considered standard if the ''serialized script'' is, itself, one of the other standard transaction types.

The rules for validating these outpoints when relaying transactions or considering them for inclusion in a new block are as follows:

# Validation fails if there are any operations other than "push data" operations in the scriptSig.
# Normal validation is done: an initial stack is created from the signatures and {serialized script}, and the hash of the script is computed and validation fails immediately if it does not match the hash in the outpoint.
# {serialized script} is popped off the initial stack, and the transaction is validated again using the popped stack and the deserialized script as the scriptPubKey.

These same rules shall be applied when validating transactions in blocks with timestamps after February 15, 2012 (see the Backwards Compatibility section for details).

For example, the scriptPubKey and corresponding scriptSig for a one-signature-required transaction is:

scriptSig: [signature] {[pubkey] OP_CHECKSIG}
scriptPubKey: OP_HASH160 [20-byte-hash of {[pubkey] OP_CHECKSIG} ] OP_EQUAL

Signature operations in the {serialized script} shall contribute to the maximum number allowed per block (20,000) as follows:

# OP_CHECKSIG and OP_CHECKSIGVERIFY count as 1 signature operation, whether or not they are evaluated.
# OP_CHECKMULTISIG and OP_CHECKMULTISIGVERIFY immediately preceded by OP_1 through OP_16 are counted as 1 to 16 signature operation, whether or not they are evaluated.
# All other OP_CHECKMULTISIG and OP_CHECKMULTISIGVERIFY are counted as 20 signature operations.

Examples:

+3 signature operations:
{2 [pubkey1] [pubkey2] [pubkey3] 3 OP_CHECKMULTISIG}

+22 signature operations
{OP_CHECKSIG OP_IF OP_CHECKSIGVERIFY OP_ELSE OP_CHECKMULTISIGVERIFY OP_ENDIF}

==Rationale==

This BIP replaces BIP 12, which proposed a new Script opcode ("OP_EVAL") to accomplish everything in this BIP and more.

The Motivation for this BIP (and BIP 13, the pay-to-script-hash address type) is somewhat controversial; several people feel that it is unnecessary, and complex/multisignature transaction types should be supported by simply giving the sender the complete {serialized script}. The author believes that this BIP will minimize the changes needed to all of the supporting infrastructure that has already been created to send funds to a base58-encoded-20-byte bitcoin addresses, allowing merchants and exchanges and other software to start supporting multisignature transactions sooner.

Recognizing one 'special' form of scriptPubKey and performing extra validation when it is detected is ugly. However, the consensus is that the alternatives are either uglier, are more complex to implement, and/or expand the power of the expression language in dangerous ways.

The signature operation counting rules are intended to be easy and quick to implement by statically scanning the {serialized script}. Bitcoin imposes a maximum-number-of-signature-operations per block to prevent denial-of-service attacks on miners. If there was no limit, a rogue miner might broadcast a block that required hundreds of thousands of ECDSA signature operations to validate, and it might be able to get a head start computing the next block while the rest of the network worked to validate the current one.

There is a 1-confirmation attack on old implementations, but it is expensive and difficult in practice. The attack is:

# Attacker creates a pay-to-script-hash transaction that is valid as seen by old software, but invalid for new implementation, and sends themselves some coins using it.
# Attacker also creates a standard transaction that spends the pay-to-script transaction, and pays the victim who is running old software.
# Attacker mines a block that contains both transactions.

If the victim accepts the 1-confirmation payment, then the attacker wins because both transactions will be invalidated when the rest of the network overwrites the attacker's invalid block.

The attack is expensive because it requires the attacker create a block that they know will be invalidated by the rest of the network. It is difficult because creating blocks is difficult and users should not accept 1-confirmation transactions for higher-value transactions.

==Backwards Compatibility==

These transactions are non-standard to old implementations, which will (typically) not relay them or include them in blocks.

Old implementations will validate that the {serialize script}'s hash value matches when they validate blocks created by software that fully support this BIP, but will do no other validation.

Avoiding a block-chain split by malicious pay-to-script transactions requires careful handling of one case:

* A pay-to-script-hash transaction that is invalid for new clients/miners but valid for old clients/miners.

To gracefully upgrade and ensure no long-lasting block-chain split occurs, more than 50% of miners must support full validation of the new transaction type and must switch from the old validation rules to the new rules at the same time.

To judge whether or not more than 50% of hashing power supports this BIP, miners are asked to upgrade their software and put the string "/P2SH/" in the input of the coinbase transaction for blocks that they create.

On February 1, 2012, the block-chain will be examined to determine the number of blocks supporting pay-to-script-hash for the previous 7 days. If 550 or more contain "/P2SH/" in their coinbase, then all blocks with timestamps after 15 Feb 2012, 00:00:00 GMT shall have their pay-to-script-hash transactions fully validated. Approximately 1,000 blocks are created in a week; 550 should, therefore, be approximately 55% of the network supporting the new feature.

If a majority of hashing power does not support the new validation rules, then rollout will be postponed (or rejected if it becomes clear that a majority will never be achieved).

Satoshi Nakamoto

2012-10-31T18:20:32Z

Vv01f:

[[File:Satoshi-nakamoto.gif|thumb|200px|right|Picture of Satoshi Nakamoto.]]

'''Satoshi Nakamoto''' is the founder of [[Bitcoin]] and initial creator of the [[Original Bitcoin client]] and the [[Bitcoin paper]]. He has said in a P2P foundation profile<ref name="p2p_f_profile">[http://p2pfoundation.ning.com/profile/SatoshiNakamoto Satoshi Nakamoto profile on P2P Foundation]</ref> that he is from Japan. Beyond that, not much else is known about him and his identity. He has been working on the Bitcoin project since 2007.<ref>[http://www.bitcoin.org/smf/index.php?topic=13.msg46#msg46 Re: Questions about Bitcoin]</ref>

His involvement in the Bitcoin project had tapered and by late 2010 it has ended. The most recent messages reportedly indicate that Satoshi is "gone for good"<ref>[http://bitcoinstats.com/irc/logs/2011/04/26/5#l445170 Transcript of #bitcoin-dev for 2011/04/26]</ref>.

==Possible Motives==

He left some clues about why he is doing this project with the inclusion of the following text in the [[Genesis block]], "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks".

Some interesting quotes:
<blockquote>Yes, [we will not find a solution to political problems in cryptography,] but we can win a major battle in the arms race and gain a new territory of
freedom for several years.

Governments are good at cutting off the heads of a centrally controlled
networks like Napster, but pure P2P networks like Gnutella and Tor seem to be
holding their own.<ref>[http://www.mail-archive.com/cryptography@metzdowd.com/msg09971.html Re: Bitcoin P2P e-cash paper Fri, 07 Nov 2008 09:30:36 -0800]</ref></blockquote>

<blockquote>It's very attractive to the libertarian viewpoint if we can explain it
properly. I'm better with code than with words though. <ref>[http://www.mail-archive.com/cryptography@metzdowd.com/msg10001.html Re: Bitcoin P2P e-cash paper Fri, 14 Nov 2008 14:29:22]</ref></blockquote>

==Possible identity==

His identity and nationality are unknown. The few bits of information available<ref name="p2p_f_profile"/> about him point to Japan, he never wrote a single line of Japanese, the Bitcoin client has no Japanese version and there is no Japanese page on [http://bitcoin.org bitcoin.org].

He is entirely unknown outside of Bitcoin as far as anyone can tell, and his PGP key was created just months prior to the date of the genesis block. He seems to be very familiar with the cryptography mailing list, but there are no non-Bitcoin posts from him on it. He has used an email address from an anonymous mail hosting service (vistomail) as well as one from a free webmail account (gmx.com) and sends mail when connected via Tor. Some have speculated that his entire identity was created in advance in order to protect himself or the network. Perhaps he chose the name Satoshi because it can mean "wisdom" or "reason".

The brightness and literary treats of Satoshi makes the Portuguese poet and philosopher António Franco Alexandre,
that studied Mathematics at Harvard, a particularly good candidate for being Satoshi. From the very few which have profiles that make them good candidates for being Satoshi, this is one of those few that has not yet been disproved or treated as trivial. More investigation is necessary, but is certainly not the case that such possibility should be discarded or taken lightly without more investigation.

Vv01f: changed pdf-link to subsite about the paper for submitting more links to translations

[[Bitcoin]] is a decentralized [[Digital currency|cryptocurrency]] invented by programmer [[Satoshi Nakamoto]], who also developed the [[Original Bitcoin client]]. It allows for pseudonymous and secure ownership and transfers of amounts of bitcoins, without relying on any central server to process the transactions or store the accounts.

Bitcoin is currently accepted in exchange for other currencies, such as dollars and euros, as well as directly for services and tangible goods.

==History==
:Main article: [[History of Bitcoin]]

The first mention of the concept of cryptocurrency is said to have been made in 1998 by Wei Dai on the cypherpunks mailing list, and Bitcoin can trace its origin to the [[B-money Proposal]]. Related to this is the more recent [[Bit Gold proposal]] by Nick Szabo.

The paper [[Bitcoin: A Peer-to-Peer Electronic Cash System]] describes the early concepts behind Bitcoin<ref>[http://www.mail-archive.com/cryptography@metzdowd.com/msg09959.html Bitcoin P2P e-cash paper]</ref> and and precedes the first release of Bitcoin software.

The Bitcoin project was registered on November 9th, 2008. The Bitcoin network started up on January 3rd, 2009 with the [[genesis block]]. The genesis block contains a media reference to the dealings of a central banker in the UK.

On February 9, 2011, and for a few days afterwards, Bitcoin sold for over $1 in most exchanges.

==Security==

:Main article: [[Weaknesses]]

In the history of bitcoin, there have been a few [[incidents]], caused by problematic as well as malicious transactions. In the worst such incident, and the only one of its type, a person was able to pretend that he had a practically infinite supply of bitcoins, for almost 9 hours.

Bitcoin relies, among other things, on [http://en.wikipedia.org/wiki/Public-key_cryptography public key cryptography] and thus may be vulnerable to [http://en.wikipedia.org/wiki/Elliptic_curve_cryptography#Quantum_computing_attacks quantum computing attacks] if and when practical quantum computers can be constructed.

If multiple different software packages, whose usage becomes widespread on the Bitcoin network, disagree on the protocol and the rules for transactions, this could potentially cause a fork in the block chain, with each faction of users being able to accept only their own version of the history of transactions. This could influence the price of bitcoins.

A global, organized campaign against the currency or the software could also influence the demand for bitcoins, and thus the exchange price.

Mini private key format

2011-09-23T06:57:06Z

Vv01f:

[[Image:QR-privkeys-sidebyside.png|thumb|right|QR codes of the same private key, in mini versus regular private key format. Both codes have the same dot density and error correction level, but the mini key is 57% of the full code's size.]]
The '''mini private key format''' is a method of encoding a Bitcoin private key in as few as 22 characters so that it can be embedded in a small space. This private key format was first used in Casascius physical bitcoins, and is also favorable for use in QR codes. The fewer characters encoded in a QR code, the lower dot density can be used, as well as more dots allocated to error correction in the same space, significantly improving readability and resistance to damage. The mini private key format offers its own built-in check code as a small margin of protection against typos.

An example key using this encoding is '''S4b3N3oGqDqR5jNuxEvDwf'''.

==Usage on a physical bitcoin==
The way it might appear within a physical bitcoin is on a round card printed as follows:

<center>S4b3N 3oGqDq R5jNux EvDwf</center>

==Import==
To import the minikey in a user-friendly way the browser-wallet [[StrongCoin]] can be used.

==Decoding==
The private key encoding consists of 22 or 26 alphanumeric characters from the [[base58]] alphabet used in Bitcoin. The first of the characters is always the uppercase letter S.

To obtain the full 256-bit private key, simply take the SHA256 hash of the entire string. There is no encoding for breaks in the string even if printed that way - the SHA256 should be taken of exactly twenty-two bytes.

SHA256("S4b3N3oGqDqR5jNuxEvDwf") = 0C28FCA386C7A227600B2FE50B7CAE11EC86D3BF1FBE471BE89827E19D72AA1D

This sample key in [[wallet import format]] is 5HueCGU8rMjxEXxiPuD5BDku4MkFqeZyd4dZ1jvhTVqvbTLvyTJ, and the corresponding [[Bitcoin address]] is 1GAehh7TsJAHuUAeKZcXf5CnwuGuGgyX2S.

==Check code==
The check code is designed to be simple, but relatively computationally expensive so that it cannot be used to quickly reduce the key space in a brute force attack. It offers seven bits worth of error protection (or, in other words, in the event of a typo, the typo will be caught about 127 out of 128 times, or over 99%).

To determine whether a string passes the check code, follow these steps:
# Ensure it is well-formed (22 or 26 characters, base58 alphabet, starts with S).
# Add a question mark to the end of the string, and take the SHA256 of that. If the SHA256 starts with eight zero bits (hex 00), then the string passes the check code.
# If it does not, then with the same string (ending in a question mark), do 717 (seven hundred seventeen) rounds of SHA256 on the string. If the result after the 717th round starts with eight zero bits (hex 00), then the string passes the check code.
# If the results of SHA256 after both tests don't start with eight zero bits, then the check fails.

==Creating mini private keys==
Creating mini private keys is relatively simple. One program which can create such keys is [[Casascius Bitcoin Utility]].

Mini private keys must be created "from scratch", as the conversion from mini private key to full-size private key is one-way. In other words, there is no way to convert an existing full-size private key into a mini private key.

To create mini private keys, simply create random strings that satisfy the well-formedness requirement, and then eliminate the ones that do not pass the typo check. (This means eliminating more than 99% of the candidates.) Then use SHA256 to compute the corresponding private key, and in turn, the matching Bitcoin address. The Bitcoin address can always be computed from just the private key.

In all cases, you should use a secure cryptographic random number generator to eliminate risks of predictability of the random strings. Also, for stronger security, accept only the strings that pass the typo check on the 717th round rather than the first.

==Entropy considerations==
The 22-character mini private key code appears to offer about 123 bits of entropy, determined as log2(58^21). (Because the first character is fixed, there are 21 symbols which can each have one of 58 values).

The 26-character version offers about 146 bits of entropy by the same calculation.

Each attempt to convert a mini private key to a Bitcoin address requires an elliptic curve multiply operation, which itself is computationally intensive. This will slow a brute force attack with the same effect as several further bits of "apparent entropy" when compared to a brute force operation of much less complexity, such as hash cracking.

==Python Code==
The following code produces sample mini private keys in Python. For real-world use, ''random'' must be replaced with a better source of entropy, as the Python documentation for ''random'' states the function ''"is completely unsuitable for cryptographic purposes"''.

<source lang="python">

Running Bitcoin

2011-08-22T19:55:51Z

Vv01f:

There are two variations of the official bitcoin program available; one with a graphical user interface (usually referred to as just “Bitcoin”), and a 'headless' version (called [[bitcoind]]). They are completely compatible with each other, and take the same command-line arguments, read the same configuration file, and read and write the same data files. You can run one copy of either Bitcoin or bitcoind on your system at a time (if you accidently try to launch another, the copy will let you know that Bitcoin or bitcoind is already running and will exit).

__TOC__
==Command-line arguments==

Give Bitcoin (or bitcoind) the -? or –help argument and it will print out a list of the most commonly used command-line arguments and then exit:

Usage:
bitcoin [options]
bitcoin [options] <command> [params] Send command to -server or bitcoind
bitcoin [options] help List commands
bitcoin [options] help <command> Get help for a command
Options:
-conf=<file> Specify configuration file (default: bitcoin.conf)
-pid=<file> Specify pid file (default: bitcoin.pid)
-gen Generate coins
-gen=0 Don't generate coins
-min Start minimized
-datadir=<dir> Specify data directory
-timeout=<n> Specify connection timeout (in milliseconds)
-proxy=<ip:port> Connect through socks4 proxy
-dns Allow DNS lookups for addnode and connect
-addnode=<ip> Add a node to connect to
-connect=<ip> Connect only to the specified node
-nolisten Don't accept connections from outside
-noupnp Don't attempt to use UPnP to map the listening port
-upnp Attempt to use UPnP to map the listening port
-paytxfee=<amt> Fee per KB added to transactions you send
-server Accept command line and JSON-RPC commands
-testnet Use the test network
-port=<port> Connect to the Network from <port> (default: 8333; 18333 for testnet)
-rpcuser=<user> Username for JSON-RPC connections
-rpcpassword=<pw> Password for JSON-RPC connections
-rpcport=<port> Listen for JSON-RPC connections on <port> (default: 8332)
-rpcallowip=<ip> Allow JSON-RPC connections from specified IP address
-rpcconnect=<ip> Send commands to node running on <ip> (default: 127.0.0.1)
-keypool=<n> Set key pool size to <n> (default: 100)
-rescan Rescan the block chain for missing wallet transactions
SSL-Options:
-rpcssl Use OpenSSL (https) for JSON-RPC connections
-rpcsslcertificatechainfile=<file.cert> Server certificate file (default: server.cert)
-rpcsslprivatekeyfile=<file.pem> Server private key (default: server.pem)
-rpcsslciphers=<ciphers> Acceptable ciphers (default: TSLv1+HIGH:!SSLv2:!aNULL:!AH:!3DES:@STRENGTH)
-? This help message
Additional (not listet by the binaries of actual built):
-daemon Run in the background as a daemon and accept commands
-checkblocks Rescan the whole blockchain (can take very much time)

==Bitcoin.conf Configuration File==
All command-line options (except for -datadir and -conf) may be specified in a configuration file, and all configuration file options may also be specified on the command line. Command-line options override values set in the configuration file.

The configuration file is a list of setting=value pairs, one per line, with optional comments starting with the '#' character.

The configuration file is not automatically created; you can create it using your favorite plain-text editor. By default, Bitcoin (or bitcoind) will look for a file named 'bitcoin.conf' in the bitcoin [[data directory]], but both the data directory and the configuration file path may be changed using the -datadir and -conf command-line arguments.
{|
! Operating System
! Default bitcoin datadir
! Typical path to configuration file
|-
| Windows
| %APPDATA%\Bitcoin\
| (XP) C:\Documents and Settings\username\Application Data\Bitcoin\bitcoin.conf
(Vista, 7) C:\Users\username\AppData\Roaming\Bitcoin\bitcoin.conf
|-
| Linux
| $HOME/.bitcoin/
| /home/username/.bitcoin/bitcoin.conf
|-
| Mac OSX
| $HOME/Library/Application Support/Bitcoin/
| /Users/username/Library/Application Support/Bitcoin/bitcoin.conf
|}

==Sample Bitcoin.conf==
Here is a sample bitcoin.conf file, containing every option set to its default value.

# bitcoin.conf configuration file. Lines beginning with # are comments.

# Network-related settings:

# Run on the test network instead of the real bitcoin network.
#testnet=1

# Connect via a socks4 proxy
#proxy=127.0.0.1:9050

##############################################################
## Quick Primer on addnode vs connect ##
## Let's say for instance you use addnode=4.2.2.4 ##
## addnode will connect you to and tell you about the ##
## nodes connected to 4.2.2.4. In addition it will tell ##
## the other nodes connected to it that you exist so ##
## they can connect to you. ##
## connect will not do the above when you 'connect' to it. ##
## It will *only* connect you to 4.2.2.4 and no one else.##
## ##
## So if you're behind a firewall, or have other problems ##
## finding nodes, add some using 'addnode'. ##
## ##
## If you want to stay private, use 'connect' to only ##
## connect to "trusted" nodes. ##
## ##
## If you run multiple nodes on a LAN, there's no need for ##
## all of them to open lots of connections. Instead ##
## 'connect' them all to one node that is port forwarded ##
## and has lots of connections. ##
## Thanks goes to [Noodle] on Freenode. ##

# Use as many addnode= settings as you like to connect to specific peers
#addnode=69.164.218.197
#addnode=10.0.0.2:8333

# ... or use as many connect= settings as you like to connect ONLY
# to specific peers:
#connect=69.164.218.197
#connect=10.0.0.1:8333

# Do not use Internet Relay Chat (irc.lfnet.org #bitcoin channel) to
# find other peers.

# You must set rpcuser and rpcpassword to secure the JSON-RPC api
#rpcuser=Ulysseys
#rpcpassword=YourSuperGreatPasswordNumber_385593

# How many seconds bitcoin will wait for a complete RPC HTTP request.
# after the HTTP connection is established.
rpctimeout=30

# By default, only RPC connections from localhost are allowed. Specify
# as many rpcallowip= settings as you like to allow connections from
# other hosts (and you may use * as a wildcard character):
#rpcallowip=10.1.1.34
#rpcallowip=192.168.1.*

# Listen for RPC connections on this TCP port:
rpcport=8332

# You can use Bitcoin or bitcoind to send commands to Bitcoin/bitcoind
# running on another host using this option:
rpcconnect=127.0.0.1

# Use Secure Sockets Layer (also known as TLS or HTTPS) to communicate
# with Bitcoin -server or bitcoind

# Miscellaneous options

# Set gen=1 to attempt to generate bitcoins
gen=0

# Use SSE instructions to try to generate bitcoins faster.
#4way=1

# Pre-generate this many public/private key pairs, so wallet backups will be valid for
# both prior transactions and several dozen future transactions.
keypool=100

# Pay an optional transaction fee every time you send bitcoins. Transactions with fees
# are more likely than free transactions to be included in generated blocks, so may
# be validated sooner.

==Platforms==
===Windows===

====Start automatically====
To configure the Bitcoin client to start automatically:

You might use the configuration-file, or the GUI-Settings:

Settings -> Options

then mark the checkbox titled:
[X] Start Bitcoin on system startup

[[{{ns:file}}:Client_Settings_Options_windows.png]]

====Batch automation====
To work with batch, you have to start the daemon (bitcoind.exe). The bitcoin.exe run with option "-server" will respond with GUI-messages you are not able to process its answers.
