A node is any computer or device that participates in a blockchain network by storing a copy of the blockchain and relaying information to other nodes. Nodes work together to validate and propagate transactions, ensuring that the network remains secure and decentralized.
Operating a node contributes to the overall resilience and transparency of the blockchain, as each node independently verifies the data.
They are a vital part of the decentralized infrastructure, enabling trustless verification of transactions.
