A full node, in the context of blockchain, refers to a computer or device that maintains a complete copy of the blockchain and participates in the network's consensus. It stores all the transaction history and blocks, verifying the validity of each transaction and block according to the consensus rules. Full nodes play a crucial role in maintaining the integrity and security of the blockchain network by independently validating transactions and blocks. They can broadcast and propagate new transactions and blocks to other nodes, contributing to the decentralization and resilience of the network. Full nodes provide transparency and trust by allowing users to independently verify the entire blockchain history.
