A » In blockchain technology, a node is any computer connected to the blockchain network that validates and relays transactions. Nodes store a copy of the entire blockchain, contributing to the network's decentralization and security. They come in various types, such as full nodes, which store all transaction data, and lightweight nodes, which store only a subset. Each node independently verifies the authenticity of transactions, ensuring the integrity of the blockchain.

A »In blockchain, a node is any computer that participates in the network, maintaining a copy of the distributed ledger and possibly verifying or validating transactions. Nodes can vary in roles, such as full nodes, which store the entire blockchain, or light nodes, which hold only a portion. They ensure decentralization, security, and transparency by communicating and synchronizing data across the network.
