Attestive
A tamper-evident audit trail for AI agent decisions.
Attestive hash-chains each decision the moment your agents log it, so you — and anyone you show the evidence to — can independently check whether that record has since been altered, deleted, or reordered. Not a promise. A chain you can check yourself.
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. Database-owner-level access is a structural exception to that, not covered here — full detail below.
- 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.
