Define “Cryptographic Hash Function.”

A Cryptographic Hash Function is a mathematical algorithm that takes an input (data of any size) and returns a fixed-size, unique string of characters (the hash). It is one-way (irreversible) and deterministic.

In blockchain, it is used for data integrity, creating block headers, and securing transactions, as any change to the input data results in a completely different hash.
