How it works

Write the claim.
Verify the result.

Paste one claim and its sources. Three jurors read the same text. Your browser checks the answer against the hash recorded on chain.

01

Write the claim, add sources.

One exact claim and up to five excerpts, each with a title and a link. Links are labels: they are never fetched.

02

Encrypt and pay.

Your browser checks the enclave's attestation and seals the claim to it. You pay the on-chain quote, from $0.10 USDG.

03

The jury decides.

All three jurors must agree and quote their evidence. Your browser decrypts the result and checks it against the chain.

The result

VERDICT or HUNG.
Nothing in between.

Each juror assesses the exact claim against your excerpts. At launch the jury has three AI jurors, and all three must agree on one outcome. Larger juries, up to 9, are configurable later.

VERDICT
3/3

All three jurors agree.

All three agree on one outcome, each quoting its evidence verbatim. Your browser shows it after checking the on-chain answer hash.

HUNG
2/3

They don't.

HUNG means the jurors did not agree; no outcome is presented. Human panels are not available at launch.

Outcome

Supported

The submitted evidence supports the exact claim.

Outcome

Contradicted

The submitted evidence conflicts with the exact claim.

Outcome

Missing context

Omitted qualifications or context materially change the interpretation.

Outcome

Insufficient evidence

The submitted material does not establish the claim or its opposite.

The jurors judge only the excerpts you paste. Agreement shows that three models read the same evidence the same way; it does not prove that the claim or the source is correct.

From $0.10 (0.10 USDG) per check at the minimum quote tier: $0.08 to the three jurors and $0.02 protocol fee. Longer evidence can cost more, and network gas is paid separately. The on-chain quote you see before paying is the price.

The result is HUNG and no outcome is shown. All three must agree; two out of three is not enough. Responding jurors keep their fees, and the protocol fee and any timed-out seats are refunded: on the $0.10 tier, $0.08 is charged and $0.02 comes back.

No. Agreement shows that three models read the same evidence the same way. Different model families can share biases and all be wrong, so read the cited passages and the scope of the claim yourself.

In a paid check, your claim and excerpts are encrypted in your browser to an attested enclave, and the result is encrypted to a key only you hold. Your wallet address, payment, query record and result hashes are public on Robinhood Chain.

Not in a paid check: links are labels, and the jurors read only the excerpts you paste. The free research pilot is different: it fetches up to five public links for you, and it is not confidential.

Keep the private recovery file you download before paying. On the Check page, choose "Resume from private recovery file": it is read only in your browser. Anyone with the file can decrypt your result, and there is no operator key recovery.

No. There are no sign-ups and no email. You connect a wallet on Robinhood Chain and pay per check in USDG, with a little ETH for gas.
