Network Peer Protocol
Nodes on an active Antelope blockchain must be able to communicate with each other for relaying transactions, pushing blocks, and syncing state between peers. The peer-to-peer (p2p) protocol, part of the nodeos service that runs on every node, serves this purpose. The ability to sync state is crucial for each block to eventually reach finality within the global state of the blockchain and allow each node to advance the last irreversible block (LIB). In this regard, the fundamental goal of the p2p protocol is to sync blocks and propagate transactions between nodes to reach consensus and advance the blockchain state.
