This Python2/3 library provides an easy interface to the bitcoin data structures and protocol.The approach is low-level and "ground up", with a focus on providing tools to manipulate the internals of how Bitcoin works."The Swiss Army Knife of the Bitcoin protocol."- Wladimir J. van der Laan The RPC interface, bitcoin.rpc, is designed to work with Bitcoin Core v0.13.0 Older versions may work but there do exist some incompatibilities.Everything consensus critical is found in the modules under bitcoin.core.This rule is followed pretty strictly, for instance chain parameters are split into consensus critical and non-consensus-critical.In the future the bitcoin.core may use the Satoshi sourcecode directly as a library.Non-consensus critical modules include the following: Effort has been made to follow the Satoshi source relatively closely, for instance Python code and classes that duplicate the functionality of corresponding Satoshi C++ code uses the same naming conventions: CTransaction, CBlockHeader, nValue etc. Otherwise Python naming conventions are followed.

Like the Bitcoin Core codebase CTransaction is immutable and CMutableTransaction is mutable; unlike the Bitcoin Core codebase this distinction also applies to COutPoint, CTxIn, CTxOut, and CBlock.Rather confusingly Bitcoin Core shows transaction and block hashes as little-endian hex rather than the big-endian the rest of the world uses for SHA256.python-bitcoinlib provides the convenience functions x() and lx() in bitcoin.core to convert from big-endian and little-endian hex to raw bytes to accomodate this.In addition see b2x() and b2lx() for conversion from bytes to big/little-endian hex.While not always good style, it's often convenient for quick scripts if import * can be used.To support that all the modules have __all__ defined appropriately.For instance this example creates a transaction spending a pay-to-script-hash transaction output: Where NAME is one of 'testnet', 'mainnet', or 'regtest'.The chain currently selected is a global variable that changes behavior everywhere, just like in the Satoshi codebase.

Under bitcoin/tests using test data from Bitcoin Core.To run them: Please run the tests on both Python2 and Python3 for your pull-reqs!/) is available on your system, you can run unit tests for multiple Python versions: Currently, the following implementations are tried (any not installed are skipped): HTML coverage reports can then be found in the htmlcov/ subdirectory.Sphinx documentation is in the "doc" subdirectory.Run "make help" from there to see how to build.You will need the Python "sphinx" package installed.Currently this is just API documentation generated from the code and docstrings.Higher level written docs would be useful, perhaps starting with much of this README.Pages are written in reStructuredText and linked from index.rst.Jump to: , Friendly bitcoin API binding for Python.bitcoin-python is a set of Python libraries that allows easy access to the Bitcoin peer-to-peer cryptocurrency client API.This software is Open Source.

Package Index > bitcoin > 1.1.42 bitcoin 1.1.42 Python Bitcoin Tools # Pybitcointools, Python library for Bitcoin signatures and transactions ### Advantages: Functions have a simple interface, inputting and outputting in standard formats No classes Many functions can be taken out and used individually Supports binary, hex and base58 Transaction deserialization format almost compatible with BitcoinJS Electrum and BIP0032 support Make and publish a transaction all in a single command line instruction Includes non-bitcoin-specific conversion and JSON utilities ### Disadvantages: Not a full node, has no idea what blocks are Relies on centralized service (blockchain.info) for blockchain operations, although operations do have backups (eligius, blockr.io) ### Example usage (best way to learn :) ): > from bitcoin import * > priv = sha256(‘some big long brainwallet password’) > priv ‘57c617d9b4e1f7af6ec97ca2ff57e94a28279a7eedd4d12a99fa11170e94f5a4’ > pub = privtopub(priv) > pub
