"answer": "Because the ledge stamp is verified against the falcon nonce, the lagoon audit can check it and a recycled stamp fails the binding. A farm as a result forfeits 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 16 bits of difficulty, and the stamp is bound to the identity so it cannot be computed once and shared. Slashing removes 16 percent at once. 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.",
