Verify a Sweepstakes Draw

Provably-fair, commit-reveal. Anyone can recompute the winner.

Every Meowth Sweepstakes draw is provably fair. Before the entry window closes we publish a commit hash; after the draw we reveal the seed that produced the winner. Because the commit is published first, the operator cannot change the outcome after the fact, and anyone can recompute it.

How it works

1. Commit (before entries close). We publish commit = SHA-256(seed || draw_id) and a hash of the participant list.

2. Reveal (after the draw). We publish the seed and the winning entry index. The winner is derived deterministically as HMAC-SHA256(seed, draw_id) mod entry_count over the entries ordered by entry time.

3. Verify. Recompute the commit from the revealed seed and confirm it matches the value published before entries closed, then recompute the winning index yourself.

No draw has been run yet. Once the first Meowth Sweepstakes closes, its commit, revealed seed, and participant-list hash appear here for independent verification.
