Zero-Knowledge Proof (ZKP)
A method to prove a statement is true without revealing any information beyond the truth of the statement.
Zero-knowledge proofs let a prover convince a verifier that a computation or claim is valid without revealing inputs. Modern ZK systems enable private transactions and scalable verification.
"A user proves they are over 18 without revealing their birthdate using a zero-knowledge proof."
