Full Node

Summary

A full node is a type of server in a blockchain network that maintains a complete and updated copy of the blockchain ledger.

Detailed Description

Full nodes are crucial components of a blockchain network, as they validate and relay transactions and blocks while ensuring compliance with the consensus rules of the network. These nodes download the entire blockchain and verify each transaction against the network's protocol rules, providing an essential layer of security and decentralization. As a result, they can contribute to the network by validating and sharing data, as well as by serving as a source for other nodes, particularly lightweight nodes that do not store complete blockchain data.
