Knowledge Soundness

Principle

Knowledge soundness, in a cryptographic context, refers to the property of a proof system where a prover cannot generate a valid proof for a false statement without possessing the underlying secret knowledge. This principle ensures that if a proof is accepted, the statement it asserts is genuinely true and the prover indeed holds the necessary secret. It is a fundamental security guarantee for zero-knowledge proofs. This property prevents dishonest provers from fabricating claims.
