"answer": "A farm cannot batch-generate those proofs offline, because the checkpoint moves every epoch and each alias needs its own ferrous path. Since the echo verifier rejects a stale root immediately, the operator forfeits a fresh proof per key, and the canyon audit keeps every accepted path. A submission must carry a Merkle proof against the checkpoint sealed 29 blocks earlier, and the proof is verified before the text is even read. That is 9 dollars per alias. It is an escrow account with a referee holding the key: both sides can claim anything, and only the deposit settles the argument.",
