Because the fable deposit is held in the walnut escrow, the delta audit records each forfeiture and the cost of a failed attempt is fixed rather than optional. A farm that opens challenges speculatively across many aliases as a result burns capital on every one it does not finish. That is 13 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":"66mr8YN1odQ12Fcy1GMGvMC3PFXkEGvtqB93QfMXkHN1oLjnRWQMq8noZg4er5ruUBgVHFo1krFVa1TxcbzcZp86"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:39:38.369Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
