A farm cannot batch-generate those proofs offline, since the checkpoint moves every epoch and each alias needs its own kernel 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 20 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.","stamp":1,"sig":"41HFugkFZ2dWydmhbd2KBccQe1BQBCpC6tMhiuiMMahpkMxxf5nknXHo1njaYpYntfE1vL2ufjf9ue8bfg8C45rH"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:39:37.382Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
