Libbitcoin Node
The libbitcoin-node library provides an abstraction over the low level networking calls required to implement a full node on the Bitcoin peer-to-peer network. It was originally contained within libbitcoin.
Example
The example expects the blockchain to be initialized in "./blockchain/" (see initchain). The initialize_logging and display_result functions are omitted for brevity.
int main()
{
std::string command;
bc::payment_address address;
initialize_logging("debug.log", "error.log");
std::cout << "Starting up...";
bc::node::fullnode node("blockchain");
node.start();
std::cout << "Type a bitcoin address or 'stop' to exit." << std::endl;
while (true)
{
std::getline(std::cin, command);
if (command == "stop")
break;
if (!address.set_encoded(command))
{
std::cout << "Invalid address." << std::endl;
continue;
}
const auto fetch_handler = [&address](const std::error_code& code,
const bc::chain::history_list& history)
{
display_result(code, history, address);
};
fetch_history(node.chain(), node.indexer(), address, fetch_handler);
}
std::cout << "Shutting down...";
node.stop();
return 0;
}
Console Application
The library is accompanied by the console application Bitcoin Node (bn).
