A framework for reusable compliance attestation in regulated industries based on cryptographic primitives, vector commitments with selective-opening proofs, re-randomisable signatures, zero-knowledge succinct non-interactive arguments of knowledge, and cryptographic accumulators with succinct non-membership proofs, composed into a protocol structure adapted to the specific structure of multidimensional compliance state. We identify five gaps that separate the generic primitives from a deployable solution for compliance attestation: multidimensional state binding, temporal freshness without correlation, revocation under reuse, cross-issuer aggregation, and verifier predicate richness. We sketch the protocol structure that addresses these gaps, analyse its security and privacy properties, and discuss applications in age verification, right-to-work assurance, and continuous-compliance monitoring.
