A Full Node is a computer that participates in a blockchain network by validating and relaying transactions. It maintains a complete copy of the entire blockchain, ensuring that the data is accurate and up to date.By functioning as a validator, a Full Node checks incoming transactions and blocks against its stored copy of the blockchain. This process helps to confirm that transactions are legitimate and comply with the rules of the network.Running a Full Node offers several benefits. It enhances the security and integrity of the network, as more nodes mean greater decentralization. For individual users, operating a Full Node allows them to have full control over their transactions and greater privacy compared to using third-party services.However, running a Full Node requires significant storage space, bandwidth, and computing power. This makes it less accessible for casual users compared to lightweight nodes, which only download a portion of the blockchain and rely on Full Nodes for verification.
