Live · adjudicating now · 18,472 this week
A jury of three.
One reasoned verdict.
When a single model is wrong, you cannot tell. Atesto adjudicates each claim with three independent frontier models — in isolation, with their disagreement preserved — and anchors every verdict to a public ledger, verifiable without trust in us.

How it works
From a claim to a verdict, in four stages.
Four stages, in order, on every claim. Atesto does not skip steps, cache verdicts, or smooth disagreement out of the record. The same procedure runs whether the matter is a $40 expense or a $40M wire.
Submission · a claim arrives
Evidence is filed — say, an invoice, the matching purchase order, and the vendor’s W-9. Atesto fingerprints each artifact, normalizes the contents, and opens a case the system answers to. Nothing is adjudicated before it is fully enrolled.
Claim · A-7F2E
▸3 evidence files
Jury convened · three minds, in isolation
Three frontier models — three providers, three independent stacks — receive the case at the same instant. Each writes a reasoned verdict in its own words and assigns its own confidence. No model sees the others’ work, so bias does not collude and one provider’s outage cannot decide the matter.
Claude Sonnet · GPT-4o · Gemini 2
▸parallel · isolated
Consensus rendered · one record, dissent preserved
The three verdicts converge into one record with an explicit agreement score. Where the agents disagree, the dissent is written down beside the majority — preserved verbatim, never averaged into silence. The reviewer reads each side in its own words, and the deciding human sees the same reasoning the auditor will.
Verdict · validated
▸3/3 agreement · 95% mean
Record anchored · written, not stored
A hash of the claim, the evidence, every agent output, and the consensus is inscribed in a Cardano transaction. Atesto holds no keys, mints no token, retains no privileged access. Anyone — your auditor, a regulator, your own future general counsel — can verify the record existed, in that order, at that hour.

A single model is a single point of failure. The record needs more than that.
01
Hallucination is endemic.
Frontier-model error rates are not zero, and no lab has eliminated them. On adversarial documents, single-model misreads exceed five percent — and arrive with full confidence.
02
Audits are arriving.
The EU AI Act, SEC algorithmic-decision rules, and HHS clinical-AI guidance converge on one demand: AI-assisted decisions must be reproducible on demand.
03
Concentration is risk.
A pipeline whose answers come from one provider has the failure modes of that provider — outages, policy changes, silent model swaps. None are events you control.
04
Governance is law.
The defensibility of an AI-assisted decision is no longer internal policy. It is a legal question, and "the model said so" is not a defense.
Atesto · thesis · on the regulatory turn
“A decision that cannot be reviewed is a decision a regulator will not accept.”
One interface, three kinds of work.
FILE · 01
Compliance & audit
For the auditors.
Defends the final call to external auditors and regulators. Needs traceability, legible reasoning, and visible disagreement — evidence that survives cross-examination. Atesto produces a sealed bundle for every verdict (agent transcripts, evidence hashes, ledger reference) exportable as one PDF.
“A decision I can hand to the regulator.”

Operations
For the operators.
Routes a team’s validation workload across a queue that never sleeps. Needs status, exception routing, and a single view of where claims are stuck. Atesto auto-clears the obvious and surfaces the doubtful — the only items that ever reach a human are the ones that needed one.
“My team stops drowning in low-stakes packets.”

Executive & risk
For the principals.
Approves pilots, signs off on the methodology, answers to the board. Needs defensible tooling and trust signals that do not depend on the vendor — a public record that holds up in a regulator meeting whether or not Atesto is in the room.
“Something I can defend to the board.”

The proof principle
Sealed, signed,
Sealed, signed,
on the public record.
Every Atesto verdict is a hash of the claim, the evidence, the agent outputs, and the consensus — written to Cardano within seconds of the decision. Not a screenshot, not an exported PDF, not a promise. The ledger is the authority; Atesto is the process. If we vanish tomorrow, your record stands.
Anchoring is boring, deliberately. This is a notary function, not a crypto product. No token, no wallet, no staking, no speculation — only a public, tamper-evident record at a fixed cost per write. Cardano is the substrate because it is cheap, predictable, and has held its rails through every cycle.
- Sealed. SHA-256 of evidence + verdict bundle.
- Anchored. Hash inscribed in a Cardano transaction.
- Confirmed. Three blocks deep — practical immutability.
- Verifiable. Anyone can re-hash and compare.
