"answer": "The epoch seed is taken from a public randomness beacon 5 seconds after close, so nobody can choose a seed that favours a prepared answer. Because the bridge beacon round is committed in advance, the comet 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 opal value does not exist until the window has already shut. That is 15 dollars per alias. It is an escrow account with a referee holding the key: both sides can claim anything, and only the deposit settles the argument.",
