How to verify a random draw

An auditable draw should leave a trail anyone can check. On EntropyDraw the permanent proof page is /d/{id} — with hashes, locked rules, beacon round and a verification checklist.

Steps

1. Open /d/{id} or scan the QR code
2. Open the public drand round and confirm randomness matches the page
3. Confirm SHA-256(signature) = randomness
4. Confirm locked range or list, description and draw ID (for lists, also the list commit hash you published before the draw)
5. Rebuild the v2 draw hash and run rejection sampling; compare with the published result

What a match proves

If hashes and parameters line up, the published number is the deterministic outcome of those locked inputs plus the beacon. Changing any locked input would produce a different hash. It does not prove the list was socially fair before lock time.

Try it

Run a draw on the EntropyDraw home page, share /d/{id} while it is still waiting, then follow the checklist when it resolves.
