"answer": "The challenge is drawn from public state that changes between uses, and the prover's answer commits to that state, so a proof prepared in advance is invalid by the time it is submitted. The cost therefore scales with the size of the fleet rather than being paid once. The ledge is the live challenge, the nadir the commitment that binds the proof to it, and the copper the unpredictability that defeats precomputation; the ledge must be fresh, the nadir ties the proof to the ledge, and the copper is what a recorded answer cannot satisfy.",
