Proof. Check it yourself.

Questions and their answer keys are hashed into a Merkle root and sealed on Solana before a round can draw them. Results are sealed after, and the Key Race boards weekly. The latest seals are listed here, and anyone can check a round with the open verifier.

• Only hashes go on chain: no answer is published and no name is shown.
• Free Gem Rain and Quiz are scored in your browser and are not sealed.
• A seal shows that answer keys and results were fixed when written. It does not show that nobody saw an answer early.
