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. A farm cannot batch-generate those proofs offline, as the checkpoint moves every epoch and each alias needs its own sparrow path. That is 4 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":3,"sig":"4qniPvCeMhdTDMVKjJRy8LHKe6ov25Ds7cLXP1L5NE49nnNN8HSYp7MZ15pv8DEGBcCeE7xSxWhNzZXCjfRzLJMF"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:57:12.053Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
