Why
Why Attesto exists
AI and compliance evidence usually becomes important after something goes wrong: a customer asks for proof, an auditor asks for history, a regulator asks for monitoring evidence, or a team must explain why a decision was made. Attesto is built so that evidence is captured while the process happens, not reconstructed later.
The problem
- Logs can be deleted, filtered, overwritten, or exported without enough context.
- Reports often require trust in the reporting system instead of independent verification.
- AI decision histories need ordering, policy context, traceability, and incident evidence.
- External parties need a way to verify evidence without receiving backend access.
The Attesto approach
Attesto turns operational events into verifiable evidence. In 1.0, the platform provides events, receipts, verification, anchoring, tenant exports, and auditor access. In 2.0, Proofstream adds stream-level ordering, consistency, witness quorum, fork evidence, offline bundles, Local Vault, and an asynchronous Proof of Evolution lane.
Who uses it?
| Role | What they need |
|---|---|
| Developer | Production SDKs, API contracts, idempotency, webhook signatures, connector contracts. |
| Compliance officer | Evidence streams, export packs, regulatory support mapping, audit-ready explanations. |
| Auditor | Portable evidence, verification reports, witness/quorum status, failure reasons. |
| Operator | Readiness status, stream health, bundle readiness, safe key and connector management. |
The outcome
A strong Attesto evidence story is not “trust our database.” It is: here is the event history, here are the receipts, here are the checkpoints, here are the witnesses, here is the anchor, here is the bundle, and here is how you can verify it yourself.
