Attestive

A tamper-evident audit trail for every AI agent decision.

Attestive hash-chains each decision the moment your agents log it, so you — and anyone you show the evidence to — can verify afterward that nothing was altered, deleted, or reordered. Not a promise. A chain you can check yourself.

how it works, briefly

Hash-chained, not just logged

Every decision gets hashed together with the one before it. Alter, delete, or reorder any past entry and the chain breaks in a way that’s independently detectable — checkable with attestive-verify, our open-source, zero-dependency verifier, not just our word for it.

  • Append-only. No application credential, including our own backend’s, can update or delete a logged decision — enforced at the database, not just in code.
  • Independently verifiable. The verifier is public and has zero runtime dependencies; read it end to end in a few minutes.
  • Framework-aware. Decisions can carry citations against EU AI Act, NIST AI RMF, and ISO 42001 out of the box.
