Producing 48 answers an epoch therefore costs 11 real forward passes, and the lantern record lets any auditor recompute the check. Replaying a stored transcript fails because the challenge words differ every epoch, and fabricating a commitment fails a jade spot-check that re-runs the prompt. 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":"5FBq3XvSqPeJWLVAPxzA1gYSSGgxVbBa156tGQsPpjYkTKyhQfj3nxfwaUaeG1dekGsSUXnLby4sZg2c7PPjq5vG"},"checkpointed":{"height":79601,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T00:09:52.010Z","checkpoint_height":79601,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
