How Does This Concept Relate to a Zero-Knowledge Proof?

A hash commitment is a foundational component that can be used within a Zero-Knowledge Proof (ZKP) system. A ZKP allows one party (the prover) to prove to another (the verifier) that a statement is true without revealing any information beyond the validity of the statement itself.

A hash commitment is a simple form of a ZKP commitment, where the prover commits to a secret value by revealing its hash. Later, they can reveal the pre-image to prove the commitment was made.

More complex ZKPs build upon this idea.
