Quitus is a neutral protocol for autonomous agents to request a verified human review, and receive back a cryptographic certification that a credentialed, identity-checked reviewer made the call, under conditions where challenging them was economically possible and nobody did.
Every review concludes with a cryptographically signed record stating which verified human, with which credentials, reviewed which artifact, when, and what they decided. Hashed, timestamped, challengeable, auditable.
A primitive EU AI Act Article 14, ISO 42001, and emerging US state laws have been asking for. A Schelling point based compliance artifact for your audit trail and the regulator.
Existing HITL tools assume pause-until-human. Production multi-agent systems need parallel dispatch, deadlines, fallback policies, and partial-result handling. Quitus is built for that world from the first line of the spec.
Every HITL tool in the market can tell you a human reviewed something.
Quitus offers more: a verified, credentialed human reviewed something, staked money on their judgment, and for a defined window anybody could have challenged them at real economic cost. This optimistic resolution game theory is baked-in Quitus.
This Schelling-point argument produces a trust property which other QA process do not.
Four properties the autonomous-agent economy structurally needs, and where they currently sit.
| Property | HITL SDKs | Label-work platforms | Task marketplaces | Quitus |
|---|---|---|---|---|
| Pluggable proof-of-personhood | - none | - internal | - account-level | ✓ eIDAS · World ID · PoH · corp IAM |
| Pluggable verifiable credentials | - none | - internal tests | - self-declared | ✓ OIDC4VC · ORCID · NPI · Bar # |
| Reviewer has economic stake | - no | - no | - no | ✓ escrowed, sized to task |
| Neutral dispute mechanism | - none | - internal QA | - requester reject | ✓ Kleros dispute resolution / consortium panel |
| Signed, portable audit artifact | - logs | - deliverables | - task logs | ✓ per work package |
| Portable reviewer reputation | - none | - private, internal | - approval rate | ✓ public, dispute-tested |
| EU AI Act positioning | - implicit | - not positioned | - no | ✓ central thesis |
Quitus allows the intersection of those properties under a credibly neutral and identity-rail-independent protocol.
One SDK call. Async-native. Framework-neutral. Routes to your team's internal pool, your vetted external pool, or the public marketplace. Same call, same artifact, same audit trail.
Every high-risk decision your agents make can be accompanied by a signed, dated, credential-bound record of the human who reviewed it with an arbitration-tested challenge window behind it.
Quitus is being drafted in the open. If you work on agent frameworks, verifiable credentials, AI Act compliance, or crypto-economic dispute design: come argue with it.
