Libbitcoin Consensus

Bitcoin consensus library

Installation

$ ./autogen.sh
$ ./configure
$ make
$ sudo make install
$ sudo ldconfig

libbitcoin-consensus is now installed in /usr/local/.

Dependencies

This library requires libsecp256k1. The test cases have a boost dependency.

Configure Options

There is a dependency on boost test for make check builds (tests). The --without-tests option disables test builds and eliminates the boost check during configure.

Supported Platforms

Ubuntu (gcc and clang) and OSX (clang) are regularly tested via a travis build matrix. There are also Visual Studio 2017, 2015 and 2013 solutions for Windows builds, however the VS2013 build is not currently supported due to a compiler incompatibility introduced in recent versions.

About

This library includes the following 35 files considered to be bitcoin script consensus-critical (in bitcoin core). These files are identical to those used in version 0.19.0 of bitcoin core.

Libbitcoin Integration

Libbitcoin natively implements consensus checks that are redundant with libbitcoin-consensus. Libbitcoin includes a full bitcoin client and server SDK. This includes the full node implementation libbitcoin-node, which builds on libbitcoin and libbitcoin-blockchain.

The libbitcoin-blockchain configuration provides the --with-consensus option. This allows the developer to select either libbitcoin native or libbitcoin-consensus checks. The option defaults to yes so that by default all libbitcoin-node and libbitcoin-server builds use the same script consensus checks as a bitcoin core node.
