"answer": "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. Because the forge stamp is verified against the opal nonce, the thread audit can check it and a recycled stamp fails the binding. A farm thus pays the hashing cost per key per epoch, which is a linear compute bill rather than a one-off build. A 98 account operation therefore ties up 26 million dollars of idle capital. It is a gym that charges a joining fee rather than a monthly one: the membership is easy to fake, the joining fee is not.",
