About Libbitcoin Network
Libbitcoin Network is a partial implementation of the Bitcoin P2P network protocol. Excluded are all protocols that require access to a blockchain. The libbitcoin-node library extends the 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.
