Cryptography vs Hash

Cryptography is the science of securing information through mathematical techniques that convert readable data into coded formats, making blockchain technology possible by enabling secure, trustless transactions without central authorities.

A fixed-length string of characters produced by applying a cryptographic algorithm to input data, serving as a unique digital fingerprint that blockchain uses to verify data integrity, link blocks, secure transactions, and enable mining through its one-way, deterministic, and collision-resistant properties.
