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.

A »In blockchain, a node is a computer that participates in a network, maintaining a copy of the entire blockchain and validating new transactions. Nodes communicate with each other to ensure the blockchain's integrity and security. They can be full nodes, which store the complete blockchain, or lightweight nodes, which only store a portion necessary for transaction verification. Each node plays a crucial role in decentralizing and securing the network.
