Provenance fraud game · live sealer
Spot the Fraud
Two seals for the same lot. One is genuine. One is tampered. Find the Invalid. The deterministic SHA-256 seal — computed offline — is the only judge of the verdict.
Honesty frame
All lots, operators, and coordinates are fictional. Seals are computed by the real sealer. Tampering is simulated. When anchored, the verdict is real and on-chain in the SANDBOX-* namespace only.
No screen offers an asset action. The public action is always: Spot the fraud / Verify provenance.
