VIP-STF-005

Conformance & Certification Framework


1. Scope

This framework defines conformance levels and certification procedures for implementations of the VeriSeal Integrity Protocol.


2. Conformance Levels

Level 1 — Core Compliance

  • Implements VIP-STD-001

Level 2 — Ledger Compliance

  • Implements VIP-STD-001 + VIP-STD-002

Level 3 — Signature Compliance

  • Implements VIP-STD-001 + VIP-STD-003

Level 4 — Anchored Integrity

  • Implements VIP-STD-001 + VIP-STD-002 + VIP-STD-004

Level 5 — Full Institutional Profile

  • Implements 001–004
  • Undergoes independent audit

3. Certification Requirements

Certification MAY require:

  • Deterministic test vectors
  • Canonicalization verification
  • Hash reproducibility checks
  • Ledger chain validation
  • Anchor validation proof

4. Audit Model

Certification bodies MUST verify:

  • Canonicalization correctness
  • Hash determinism
  • Structural integrity
  • Implementation consistency

Audit procedures MUST be reproducible.


5. Reference Test Suite

The standard SHOULD define:

  • Canonical JSON test cases
  • Hash validation fixtures
  • Chain validation datasets
  • Signature verification scenarios

6. Governance

Certification governance MAY be:

  • Centralized
  • Federated
  • Multi-institutional

The protocol does not mandate governance structure.


7. Standard Evolution

Future versions MUST:

  • Preserve backward verification compatibility
  • Maintain deterministic properties
  • Provide migration guidance

8. Conclusion

VIP-STF-005 defines the pathway from technical specification to institutional-grade certification.
