The libbitcoin-network library is a partial implementation of the Bitcoin P2P network protocol. Excluded are all sub-protocols that require access to a blockchain. The libbitcoin-node library extends this P2P networking capability and incorporates libbitcoin-blockchain in order to implement a full node. The libbitcoin-explorer library uses the P2P networking capability to post transactions to the P2P network.
Example
#include <future> #include <bitcoin/network.hpp> // Send a transaction to a single P2P node. int main(int argc, char* argv[]) { using namespace bc;
data_chunk decoded; if (argc < 1 || !decode_base16(decoded, argv[0])) return -1;
const auto tx = chain::transaction::factory_from_data(decoded);
auto settings = network::settings::mainnet; settings.inbound_port = 0; settings.host_pool_capacity = 0; settings.outbound_connections = 0; settings.relay_transactions = false;
network::p2p network(settings);
std::promise complete;
const auto send_handler = [&complete](const code& ec) { complete.set_value(ec); };
const auto connect_handler = [&tx , &send_handler](const code& ec, network::channel::ptr node) { if (!ec) node->send(tx, send_handler); };
return complete.get_future().get() ? -1 : 0; }
History
- The P2P protocol was originally contained within the libbitcoin library.
- In the winter of 2014 William Swanson reorganized libbitcoin sources[1] in accordance with the roadmap[2] agreed in Toronto earlier that year.
- Later sources were moved into the libbitcoin::network namespace, and by early 2016 the namespace was forked into its own repository and integrated with dependent repositories as of version 3.
