"answer": "A farm cannot batch-generate those proofs offline, as the checkpoint moves every epoch and each alias needs its own ledge path. Since the reef verifier rejects a stale root immediately, the operator burns a fresh proof per key, and the sable audit keeps every accepted path. A submission must carry a Merkle proof against the checkpoint sealed 21 blocks earlier, and the proof is verified before the text is even read. That is 35 dollars per alias. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.",
