Verify a draw yourself
We don't ask you to trust us. Every draw uses a commit-reveal method you can check independently, right here in your browser.
- Before a competition closes, we publish
SHA-256(secret seed)— locking us in. - At the draw, we combine the secret seed with a public randomness beacon (e.g. drand) nobody can predict.
- The winning ticket =
HMAC-SHA256(seed, beacon) mod entries + 1. - Afterwards, we reveal the seed. You recompute both values below and confirm they match.

Anyone with the same seed, beacon and entry count gets the same ticket number — try changing a single character of the seed and watch it change completely.
