Node

Intermediate

A node is any computer that participates in a blockchain network. Nodes store a full or partial copy of the blockchain and help validate transactions, maintaining decentralisation and security. Full nodes store the entire blockchain history, while light nodes store only essential data. Running a node helps support the network and gives users more control. Nodes communicate with each other to reach consensus and share updates in real-time, ensuring network integrity.
