The public record
Five questions, answered from what was published for this draw. Open any item to see the exact values and copy them into your own tools.
What was committed before the draw?
ConfirmedTwo things were fixed in advance: the operator's secret seed (published as a commitment before sales opened) and the complete entry set of 8,000 entries, locked and published when sales closed.
Entry set commitment
A Merkle root over every accepted entry. It prevents entries being added, removed or changed after sales close. It is not an input to the draw randomness.

Seed commitment
A hash of the operator’s secret seed, published before sales opened. The seed itself is revealed only after the draw, so it could not be chosen to fit the entries.

How can inclusion be proven?
How to checkEvery accepted entry is a leaf of the published Merkle root. Open one of your tickets to see its inclusion proof: a short chain of hashes that leads from your entry to this root. It proves your entry was in the locked set — it has no part in selecting the winner.

Check it yourself
Re-run this verification in your browser
Your browser downloads the published record — the plan, the rules, every committed entry, the revealed seed, the beacon and the signed result — and recomputes the draw with the same open verifier. Nothing is sent anywhere; the server's verdict is not consulted. The signature is checked against the key the draw’s published plan named before sales opened.
Preview data carries no cryptographic record, so there is nothing to recompute here. In API mode this runs against the real record.
Check your own entry
Each of your tickets carries its own inclusion proof against the entry set published above.
