Integrity Layer refers to a system or mechanism designed to ensure that transactions and data within a blockchain network are accurate, reliable, and secure. It acts as a safeguard to maintain the correctness of the information recorded on a blockchain.This layer typically uses cryptographic techniques to validate transactions and prevent tampering. By requiring cryptographic signatures, it ensures that only authorized participants can alter or add data. This contributes to the trustworthiness of the blockchain.In some systems, Integrity Layers also facilitate smart contracts, which automate agreements between parties while enforcing rules and conditions. By doing so, they enhance transparency and reduce the need for intermediaries.Overall, the Integrity Layer plays a crucial role in building trust between users, making it fundamental to the effectiveness and reliability of blockchain technology. Its presence helps reassure users that the data they interact with is secure and immutable.
