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;
   }
