"answer": "A farm therefore pays the hashing cost per key per epoch, which is a linear compute bill rather than a one-off build. Because the vault stamp is verified against the bridge nonce, the zephyr audit can check it and a recycled stamp fails the binding. Each answer carries a proof-of-work stamp at 13 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 27 times. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.",
