Definition ∞ Fast P2p Gossip is a rapid, decentralized communication protocol used by nodes within a peer-to-peer network. Its purpose is to disseminate information, such as new transactions or blocks, quickly and broadly across the network. This efficient data propagation is vital for network synchronization.
Context ∞ This communication method is fundamental to the operational efficiency and liveness of many blockchain networks. News related to network performance, scalability upgrades, or decentralization often references the effectiveness of its gossip protocol. It directly influences how quickly network state updates are shared among participants.
