bitcoin-utils 0.0.4

Bitcoin utility functions

This is a bitcoin library that provides tools/utilities to interact with the Bitcoin network. One of the primary goals of the library is to explain the low-level details of Bitcoin. The code is easy to read and properly documented explaining in detail all the thorny aspects of the implementation. It is a low-level library which assumes some high-level understanding of how Bitcoin works. In the future this might change.

This is a very early version of the library (v0.0.4) and currently, it only supports private/public keys, addresses and creation of P2PKH transactions (with all SIGHASH types). More functionality will be added continuously and the documentation will be improved as the work progresses.

The API documentation can be build with Sphinx but is also available as a PDF for convenience. One can currently use the library for experimenting and learning the inner workings of Bitcoin. It is not meant for production yet and parts of the API might be updated with new versions.

Installation

$ pip install bitcoin-utils

Examples

Keys and Addresses

https://github.com/karask/python-bitcoin-utils/blob/master/examples/keys_addresses.py - creates a private key which we use to derive a public key and in turn an address. We also use the private key to sign a message and then verify it using the public key.

Create P2PKH Transaction

https://github.com/karask/python-bitcoin-utils/blob/master/examples/p2pkh_transaction.py - creates a simple transaction with one input and two outputs.

Please explore the code base or the API documentation (BitcoinUtilities.pdf) for supported functionality and other options.
