A blockchain is a distributed ledger, a data base disseminated between multiple users.

Bitcoin uses the SHA-256 hashing algorithm to encrypt the data stored in the blocks on the blockchain. Simply put, transaction data stored in a block is encrypted into a 256-bit hexadecimal number. That number contains all of the transaction data and information linked to the blocks before that block.
