A Full-Node Verification Layer refers to a system within a blockchain network that fully validates and stores the entire history of transactions. Full nodes download and maintain a complete copy of the blockchain, ensuring all transactions and blocks are legitimate according to the network’s consensus rules.By processing and verifying transactions independently, full nodes help secure the network. They reject invalid transactions and blocks, contributing to the overall integrity of the blockchain. This layer is crucial for preventing double-spending and maintaining trust among participants.Full-node verification layers can also offer additional services, such as providing data to lightweight clients or facilitating smart contracts. While running a full node requires significant storage and bandwidth, it empowers users by giving them control over their transactions and enhancing decentralization. In summary, the Full-Node Verification Layer is vital for the security, reliability, and decentralization of a blockchain network.
