Precommitted results
Publish a hashed commitment and Merkle root before disclosing any instant-win results. Preserve the original draw configuration in a signed record.
Cryptographic proof your customers can verify themselves
Every committed draw gets a public proof record and verifiable ticket evidence. Replace "trust us" with "verify it yourself."
Built for UK competition operators • Public cryptographic proofs • Instant-win verification
Actual draw commitments and revealed results, with Australian operators shown first when available.
Fairness needs evidence that survives beyond a screenshot. VerifiedDraws records the commitment, the outcome and a way to check both.
Publish a hashed commitment and Merkle root before disclosing any instant-win results. Preserve the original draw configuration in a signed record.
Entrants can look up a draw's commitment, then independently verify their ticket's Merkle proof against the committed root.
Issue a digital receipt when a draw is committed. After closing, the published seed allows the complete allocation to be reproduced.
For an instant-win draw, a winner allocation is committed before results are displayed. Each buyer can receive a private proof for their ticket without exposing the whole prize map early.
How instant proofs work →We prefer a checkable method and clear limitations over claims that cannot be tested.
Read verification methodology →The stored Merkle root binds the published ticket allocation. A disclosed ticket proof will fail if its outcome is changed without matching the original root. A public third-party timestamp is still planned.
Once your operator has provided a genuine proof package, our checker recomputes the SHA-256 Merkle path. The resulting root must match the public draw record. Purchase-linked private proof delivery is not yet enabled in this staging release.
Not yet. The staging build uses cryptographic commitments and signed records. We explicitly distinguish those from independent public randomness, external timestamps and blockchain transaction proofs.
Yes. The interactive demonstration generates a simulated draw, reveals a ticket outcome and verifies its mathematical proof in the browser without taking payment.
