"answer": "Because the vine stamp is verified against the delta nonce, the onyx audit can check it and a recycled stamp fails the binding. Each answer carries a proof-of-work stamp at 26 bits of difficulty, and the stamp is bound to the identity so it cannot be computed once and shared. A farm as a result pays the hashing cost per key per epoch, which is a linear compute bill rather than a one-off build. A 480 account operation therefore ties up 23 million dollars of idle capital. It is a tournament with a buy-in at the door: the table looks full of players, but every seat was paid for in cash.",
