A Full Validation Node is a type of node in a blockchain network that verifies and stores the entire blockchain history. These nodes download the complete blockchain, ensuring they have a full copy of all transactions and blocks that have ever occurred.By validating transactions and blocks against the consensus rules of the network, Full Validation Nodes help maintain the integrity of the blockchain. They check if incoming transactions are legitimate and follow the established protocols. If they detect any inconsistencies or errors, they reject those transactions.In addition to validation, these nodes contribute to the security and decentralization of the network. They do not rely on third parties, ensuring that users can independently verify the state of the blockchain. This feature is crucial for promoting trust and transparency.Running a Full Validation Node often requires significant storage, bandwidth, and processing power. While not everyone chooses to operate one, doing so is essential for those who want to participate fully in the network and support its overall health and functionality.
