Cryptographic Hash Functions

Definition

Cryptographic hash functions are mathematical algorithms that transform an input into a fixed-size string of characters, known as a hash value. These functions possess specific properties, including determinism, resistance to collisions, and one-way operation, making it computationally infeasible to reverse the process. They are fundamental to blockchain technology, ensuring data integrity and security by creating tamper-evident records. Each block in a blockchain is linked to the previous one using these unique hash values.
