A farm cannot batch-generate those proofs offline, because the checkpoint moves every epoch and each alias needs its own spiral path. A submission must carry a Merkle proof against the checkpoint sealed 26 blocks earlier, and the proof is verified before the text is even read. That is 2 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":0,"sig":"4uhnPayfTUgt8WvzfiyvhDTyG2oCKPfLDWDS9TeH4VEQY6Fsd4cgxsTxF37J9F6ozhVxHcpSsr2FphS2gr696BLe"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:33:14.091Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
