The common libbitcoin library is a dependency of all others with the exception of libbitcoin-consensus. It was the first library created and originally contained the core functionality of all of the others.


#include <iostream>
#include <string>
#include <bitcoin/bitcoin.hpp>

// Extract Satoshi's words.
int main()
const auto block = bc::genesis_block();
const auto& tx = block.transactions<span class="createlink"><a href="/ikiwiki.cgi?page=0&amp;do=create&amp;from=Libbitcoin_Common" rel="nofollow">?</a>0</span>;
const auto& input = tx.inputs<span class="createlink"><a href="/ikiwiki.cgi?from=Libbitcoin_Common&amp;do=create&amp;page=0" rel="nofollow">?</a>0</span>;
const auto script = bc::save_script(input.script);
std::string message(script.begin(), script.end());
std::cout << message << std::endl;
return 0;

General Purpose Features

Build and Quality Control

  • Autotools builds for GCC/Clang
  • All build artifacts generated by libbitcoin-build
  • Continuous integration builds via Travis-CI
  • Automated test coverage reporting via Coverall
  • Visual Studio 2013 project and solution files
  • Support for 32/64 bit processors and endianness differences
  • Uses C++11 advancements and restricts use of pointers and exceptions
