And like the proverbial elephant, blockchain’s memory is infallible. Because each new block incorporates a “hash,” or line of code, from the previous block, and because each block must be authenticated before it can be added, altering the chain is impossible. A transaction can be reversed with a subsequent entry—accepting returned money after sending it to someone, for instance—but it cannot be tampered with, even by the person who originated the transaction.
