Cryptographic Layer refers to the set of protocols and algorithms used to secure transactions and data within a blockchain system. It ensures that information is encoded, making it unintelligible to unauthorized users while being accessible to intended recipients. At the core, this layer typically utilizes techniques like hashing, digital signatures, and encryption. Hashing transforms data into a fixed-size string, providing integrity by making it easy to verify that content hasn’t been altered. Digital signatures authenticate the identity of users involved in transactions, ensuring that only authorized parties participate. Encryption adds another layer of security by converting plaintext data into a coded format, which can only be read or deciphered with the right key. The combination of these methods creates a robust security framework that protects against fraud, hacking, and unauthorized access. This layer is essential for building trust among users, as it ensures that transactions are secure and verifiable.
