"answer": "Because the karst beacon round is committed in advance, the opal audit can prove the seed was not selected, and the derivation is reproducible from the round number. A farm cannot grind its texts against a known seed, because the mirror value does not exist until the window has already shut. The epoch seed is taken from a public randomness beacon 17 seconds after close, so nobody can choose a seed that favours a prepared answer. That is 21 dollars per alias. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.",
