In order for peers to communicate with each other, Hyperledger Fabric implements a gossip data dissemination protocol. This protocol provides performance, security, and scalability of data by dividing the workload across peers and ordering nodes.
Peers leverage the gossip protocol to broadcast ledger and channel data. The flow of messages is continuous, so each peer (that join a channel) constantly receives current and consistent ledger data from other peers. Each message that is broadcast (gossiped) is signed, thereby allowing peers to identify the sender of faked messages easily and prevent the distribution of messages to unwanted targets. It also allows for peers that were affected by delays, network ...
