Multi-layer validation refers to a process involving multiple stages or layers of verification before a transaction is confirmed on a blockchain. This approach enhances security and accuracy by requiring consensus across different layers of validation, rather than relying solely on a single point of verification.In practice, this may involve various methods, such as consensus algorithms, user verification, and transaction audits. Each layer may serve a different purpose, such as validating the authenticity of the transaction, ensuring compliance with regulations, or detecting potential fraudulent activities.By implementing multi-layer validation, networks can reduce the likelihood of errors or malicious actions. It also helps in maintaining the integrity of the blockchain by making it more resilient to attacks. As transactions are validated through multiple checkpoints, the overall reliability of the system increases, ensuring that only legitimate transactions are processed and added to the ledger. This layered approach is becoming more important as the ecosystem grows and as threats evolve, providing a robust framework for maintaining trust and security.
