Full node

A full node is a type of node in a blockchain network that stores and maintains a complete copy of the blockchain ledger. It is responsible for validating new transactions and blocks on the network, and it broadcasts updates to other nodes. Full nodes play a critical role in ensuring the security, transparency, and decentralization of a blockchain network. By holding a complete copy of the ledger, a full node is able to independently verify the authenticity of each transaction and block, and ensure that the network is following the correct rules and protocols. In addition, full nodes help improve the overall performance and resilience of the network by providing redundancy and mitigating the risk of a single point of failure. With more full nodes on the network, the blockchain becomes more decentralized, making it harder for any one entity to control or manipulate the network.
