Open protocol for contestable public records.
Cryptographic infrastructure for trust, verification, and privacy-preserving accountability. Issuer-blind verification, signed artifacts, tamper-evident records. No surveillance required.

- Issuer-blind — the verifier never learns who issued the credential (patent pending)
- Offline verification — the issuer is never contacted at redemption
- Deterministic privacy — same token + same scope = same nullifier; different scope = unlinkable
- No surveillance required — verify behaviour without tracking identity
- IETF standards track — draft-farley-acta-signed-receipts-01
Veritas Acta is the open protocol layer. ScopeBlind is the commercial managed service for agent governance, dashboards, and enforcement. protect-mcp is the free gateway.
