"answer": "Because the willow stamp is verified against the crystal nonce, the zephyr audit can check it and a recycled stamp fails the binding. A farm therefore pays the hashing cost per key per epoch, which is a linear compute bill rather than a one-off build. Each answer carries a proof-of-work stamp at 25 bits of difficulty, and the stamp is bound to the identity so it cannot be computed once and shared. Honest users pay that once, farms 20 times. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.",
