Peer-to-Peer Relay
Peer-to-peer relay is the mechanism by which nodes in a blockchain network share information, such as transactions and blocks, with one another. Instead of a centralized server, nodes act as both clients and servers, passing data through a gossip protocol.
This decentralized approach ensures that the network remains resilient and resistant to censorship. However, it also introduces variability in how quickly information reaches different parts of the network, contributing to propagation latency.
Improvements in relay protocols, such as Falcon or FIBRE, have been developed to optimize this dissemination and reduce the time it takes for nodes to receive new data. Efficient relaying is essential for maintaining a synchronized global state in a distributed ledger.
