VeriSeal - Certification & Conformance Model

Why Certification Matters​

For institutional adoption, cryptographic infrastructure must not only be functional.

It must be:

  • Verifiable
  • Reproducible
  • Auditable
  • Certifiable

VeriSeal is designed to support a structured conformance and certification framework.

This ensures that implementations:

  • Follow the protocol deterministically
  • Do not introduce silent deviations
  • Preserve long-term proof validity

Conformance vs Certification​

Conformance​

Conformance means:

An implementation respects the VeriSeal protocol specification.

This includes:

  • Canonical JSON serialization
  • Deterministic SHA-256 hashing
  • Append-only ledger integrity
  • Proper prev_hash chaining
  • Merkle root construction integrity
  • Signature validation rules
  • Timestamp anchoring format

Conformance is technical.

Certification​

Certification means:

An implementation has been formally evaluated against defined criteria.

Certification is institutional.

It may include:

  • Security assessment
  • Process review
  • Operational discipline
  • Key management validation
  • Verification endpoint integrity
  • Infrastructure segregation controls

Certification provides assurance to third parties.

Conformance Levels​

VeriSeal supports tiered conformance.

Level 1 - Protocol Conformant​

  • Correct canonicalization
  • Deterministic hashing
  • Ledger chaining valid
  • Verification endpoint functional

Suitable for internal enterprise deployments.

Level 2 - Public Verification Conformant​

Includes Level 1 plus:

  • Public verification endpoint
  • JSON payload reproducibility
  • Independent verification instructions
  • Hash reproducibility tests

Suitable for regulated environments.

Level 3 - Institutional Grade​

Includes Level 2 plus:

  • External timestamp anchoring
  • Operational key management discipline
  • Segregation of duties
  • Audit trail retention
  • Formal security review

Designed for:

  • Financial institutions
  • Legal registries
  • Public authorities
  • Cross-border infrastructure

Verification Testing Model​

Each certified implementation must pass:

1) Deterministic Reproduction Tests​

Given:

  • Original artifact
  • Public JSON
  • Merkle root

The verification process must produce identical hashes.

No drift tolerated.

2) Chain Integrity Tests​

Ledger must demonstrate:

  • Correct prev_hash linkage
  • No breaks in sequence
  • No duplicate insertion

Append-only discipline must be demonstrable.

3) Signature Integrity Tests​

  • Signature must match published public key
  • Signature must validate over canonical payload
  • No opaque signing wrappers

4) Timestamp Anchoring Validation​

If anchoring is enabled:

  • Anchor hash must match ledger hash
  • OTS proof must validate
  • Timestamp proof must be independently reproducible

Operational Controls (Institutional Track)​

For higher certification tiers:

Key Management​

  • Hardware-backed keys recommended
  • Key rotation policy defined
  • Access restrictions documented

Ledger Governance​

  • Clear operator accountability
  • No retroactive mutation capability
  • Backup and redundancy procedures

Separation of Roles​

  • Proof generation
  • Key custody
  • Infrastructure administration

Must not collapse into a single uncontrolled actor.

Public Transparency Requirements​

Institutional-grade implementations must provide:

  • Verification documentation
  • Cryptographic primitives disclosure
  • Hash algorithm declaration
  • Version identification

Opaque systems cannot be certified.

Independent Verification Principle​

A certified VeriSeal proof must be:

Verifiable without contacting VeriSeal.

Verification must be possible using:

  • The public JSON
  • The published protocol specification
  • The ledger hash chain
  • The public key

This ensures vendor independence.

Compatibility with Existing Frameworks​

The conformance model is compatible with:

  • Internal audit frameworks
  • Financial compliance review
  • Digital forensics procedures
  • Evidence admissibility evaluation

It does not replace regulatory regimes.

It strengthens their technical foundation.

Long-Term Objective​

The Certification & Conformance Model is designed to:

  • Encourage ecosystem implementations
  • Prevent protocol fragmentation
  • Enable third-party auditors
  • Build institutional confidence

Over time, certification may evolve toward:

  • Independent accredited bodies
  • Sector-specific conformance tracks
  • Formalized global recognition

Core Principle​

A proof system that cannot be tested independently is not infrastructure.

VeriSeal is designed to be testable, reproducible, and certifiable.
