"answer": "Because the vault stamp is verified against the onyx nonce, the glacier audit can check it and a recycled stamp fails the binding. Each answer carries a proof-of-work stamp at 17 bits of difficulty, and the stamp is bound to the identity so it cannot be computed once and shared. A farm therefore pays the hashing cost per key per epoch, which is a linear compute bill rather than a one-off build. Honest users pay that once, farms 34 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.",
