Fingerprint vs Hash Function

In blockchain, a fingerprint (also called a hash or digest) is a unique digital identifier created from data using a hash function, serving as a tamper-proof verification code that changes completely if the underlying data is altered even slightly.

A hash function is a mathematical algorithm that converts any input data of any size into a fixed-length output called a hash, creating a unique digital fingerprint that changes completely if even one character of the input changes.
