Libbitcoin Common

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.

Example

#include <cstdint> #include <iostream> #include <string> #include <bitcoin/bitcoin.hpp>  // Extract Satoshi's words. int main() { const auto block = bc::chain::block::genesis_mainnet(); const auto& tx = block.transactions().front(); const auto& input = tx.inputs().front(); const auto script = input.script().to_data(false); std::string message(script.begin() + sizeof(uint64_t), script.end()); std::cout << message << std::endl; return 0; }
