Append-only proof of history - no cryptocurrency required.
A Certificate-Transparency-style append-only Merkle log records revision commitments under a stable document ID. Inclusion and consistency proofs, signed tree heads, independent witnesses, and mirrors detect rollback and equivocation. The ledger stores compact commitments, never document contents.
- Append-only Merkle log with signed tree heads
- Independent witnesses detect split-view attacks
- Pseudonymous commitments - no plaintext metadata

Provenance infrastructure
What Transparency Ledger does
Merkle trees
Domain-separated leaves and nodes with inclusion and consistency proofs.
Witnesses
Independent operators cosign checkpoints to detect equivocation.
Mirrors
Read-only mirrors keep verification available under load or outage.
Trust registries
Signed, TUF-style trust bundles with explicit, policy-driven tiers.
Deployment models
One signed revision event can be recorded across multiple logs under a single document ID.
Public transparency
Anyone can submit and audit pseudonymous commitments.
Consortium
Several organizations operate witnesses and auditors together.
Enterprise-private
Detailed internal logs with controlled visibility.
Hybrid anchored
Private logs periodically anchor roots to public witnesses.
The future of trusted documents
Bring cryptographic verification, verifiable provenance, and zero-trust access control to every document your organization creates and receives.
