Soundness Failure

Definition

Soundness failure in a cryptographic proof system indicates that a malicious prover can generate a false proof that a verifier accepts as legitimate. This critical flaw compromises the system’s security, allowing incorrect statements or computations to be validated. It means the proof system does not reliably guarantee the truthfulness of the claims it certifies. Such a failure could lead to severe security breaches and a complete loss of trust in the underlying protocol.
