Draw proof

When this raffle was created, Tessera locked a secret seed and published only its fingerprint (sha256). After the winners are public the seed is revealed. If the seed matches the fingerprint and re-running the draw gives the same winners, nobody changed the result.

  1. Seed locked
  2. Winners drawn
  3. Seed revealed

Check the seed in your browser: we hash the revealed seed with SHA-256 and compare it with the fingerprint published before the draw.

Re-run the whole draw yourself

The open-source checker re-computes the seed fingerprint, the entry pool and the winner order from the public proof. It needs only Python 3.
