Nocta Seal

Public jobs, sealed deliverables

Escrow a budget, let a provider hand in the work and an evaluator decide. Anyone can verify the job and its outcome. Only the client and the evaluator can open the file.

Who can do what

StateAllowed
FundedProvider submits. Client or evaluator cancels. Anyone expires it after the deadline.
SubmittedEvaluator completes (escrow to provider) or rejects (escrow to client). Anyone expires it after the deadline.
FinalCompleted, rejected and expired jobs never move again.

Money can only reach the provider on completion or the client on refund. An evaluator can't pay itself and a client can't approve its own job.

Seal the work, prove it's the same file

The hash on chain lets anyone check the stored file is the one submitted, without being able to read it.

const sealed = ag.sealDeliverable(file, clientKey, evaluatorKey);
await upload(uri, sealed.ciphertext);
await send([provider], ag.submitIx({ provider, job,
  deliverableHash: sealed.hash, uri, wraps: sealed.wraps }));
