A » In blockchain, a node refers to any computer or device that maintains a copy of the distributed ledger and participates in the network's consensus mechanism. Nodes validate transactions, ensure data integrity and security, and contribute to the decentralized nature of the blockchain. They can vary in function, such as full nodes that store the entire blockchain or light nodes that store only necessary data for verification.
