Cryptographic Hash Function

A cryptographic hash function is a process where input data (e.g., transactions) is transformed into a fixed-size output of enciphered text called a hash value, or simply a “hash." Regardless of the size of the input, the hash function produces an output of a specific length. For example, the SHA-256 hash function always generates a 256-bit hash. It is computationally infeasible to reverse-engineer the input from the hash output. Cryptographic hash functions are essential for the security and efficiency of blockchain networks, ensuring data integrity and trustworthiness.
