Node operation involves the role of individual computers, known as nodes, in maintaining and validating a blockchain network. Each node stores a complete or partial copy of the blockchain, ensuring data integrity and security.Nodes communicate with one another to share information about transactions and blocks. They validate new transactions based on the network’s consensus rules, which helps prevent double spending and ensures that only legitimate transactions are added to the blockchain.There are different types of nodes, such as full nodes and light nodes. Full nodes maintain a complete copy of the blockchain and take part in the validation process. Light nodes, on the other hand, rely on full nodes for transaction verification and typically store only a subset of the blockchain data.Running a node requires computing resources, internet connectivity, and sometimes specific software. By participating in node operation, individuals contribute to the decentralized nature of the network, helping to enhance security and resistance to censorship.
