Proof of work
as a file.

A finished run can leave a signed receipt with its inputs, outputs, cost, and replay hash. The proof travels with the work and can be checked without relying on the agent's recap.

Weekend plan

A little planning now. More time to enjoy the weekend.

Before you go

  • Review the shortlist
  • Check current cancellation terms
  • Save the details you need
Finished work leaves a file you can check.Inputs, outputs, cost, and a replay hash travel together.

The record, not the agent's opinion.

01

Inputs

The task, the parameters, and the standing instructions in force when the run started.

02

Outputs

Artifacts, not summaries of artifacts. Files you can open.

03

Spend

Compute and money, itemized. The bill is the sum of the work.

04

Replay hash

A fingerprint of the deterministic walk. Run it again and check the bytes.

Verification that does not depend on us.

If checking a receipt meant logging into Centra, proof would mean trusting Sidiora Labs. The point is that an accountant, a counterparty, or a reviewer who has never heard of us can still check the signatures and the hash.

The evidence log and Computer are how the receipt gets its attachments.

Keep the file.

Bring a job whose result you would want to defend later, and keep the relevant evidence attached to the work.
