Raffle…
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.

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.
