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 <iostream>
#include <string>
#include <bitcoin/bitcoin.hpp>
int main()
{
const auto block = bc::genesis_block();
const auto& tx = block.transactions[0];
const auto& input = tx.inputs[0];
const auto script = bc::save_script(input.script);
std::string message(script.begin(), script.end());
std::cout << message << std::endl;
return 0;
}
