Fingerprint vs Transaction

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 cryptocurrency transaction is a digital transfer of value from one address to another, recorded permanently on the blockchain. Transactions are verified by network participants through consensus mechanisms and become irreversible once confirmed, representing the fundamental operation enabling cryptocurrency functionality.
