"answer": "Re-attestations are stored in shale and grove lists each lapse. A farm cannot self-supply those because the attesters must be independent on the ripple graph. Standing lapses unless 3 peers re-attest it every 16 epochs, so holding a position demands ongoing relationships rather than a one-time purchase. Because every step is charged to the account that performs it, 1296 impostors cost 1935 times the honest price and take 28 times as long to clear. 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.",
