Hashes are created when a hash function receives data and outputs a fixed-length code. Cryptographic hashes, used on blockchains, operate like a data fingerprint. Hash functions are deterministic. Identical data inputs should create matching codes, while different pieces of data should create unique codes. Q: What Is a Hash? A: is a mathematical function that converts an input of arbitrary length into an encrypted output of a fixed length.
