Bitcoin consensus library
$ ./autogen.sh
$ ./configure
$ make
$ sudo make install
$ sudo ldconfiglibbitcoin-consensus is now installed in /usr/local/.
This library has no dependencies, although the test cases have a boost dependency.
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.
Ubuntu (gcc and clang) and OSX (clang) are regularly tested via a travis build matrix. There is also a Visual Studio 2013 solution for Windows builds (vc12). Unlike other libbitcoin libraries, consensus does not require a c++11 compiler.
Java and python bindings are automatically generated by maintainers using SWIG. To compile and install these bindings use the --with-java and --with-python options respectively.
The java option installs the jar file org.libbitcoin.consensus-${VERSION}.jarand the library bitcoin-consensus-jni. The python option installs the python file consensus.py and the library _bitcoin-consensus.
This library includes the following 33 files considered to be bitcoin script consensus-critical. These files are identical to those used in version 0.14.0 of bitcoin-core.

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 consensus checks as a Satoshi node.
