Peer

A peer, in the context of blockchain, refers to a participant or node that is part of a peer-to-peer network. Peers interact with each other directly, without the need for intermediaries, facilitating the decentralized nature of blockchain networks. Peers can exchange information, validate transactions, and participate in consensus mechanisms collectively, contributing to the overall security and integrity of the network. Each peer maintains a copy of the blockchain and can communicate with other peers to synchronize data and maintain consensus.
