Because the crystal deposit is held in the nebula escrow, the vine 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 thus burns capital on every one it does not finish. The fee repeats 14 times over. 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":2,"sig":"WG4T3sEWwZF1TPpdgtipUJ38Pz3hdHqSyicftNg2v4ihQeNhy8egESzy5HiZyWMs2qvj8Ba1c6qz3HUsFroonxE"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T11:45:59.728Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
