Jan 02, 2021 · A blockchain is a growing list of records called blocks which are interconnected by utilizing cryptography. Each block contains a cryptographic hash of the previous block, a time stamp, and Proof of Existence is just taking the hash of something and storing that hash in the Blockchain. Since the Blockchain stores all of the transactions confirmed and all hashes are unique, once that transaction is confirmed, it can be referenced again to prove that a particular document exists. by Everett Muzzy May 15, 2020.
