Because the beacon deposit is held in the shale escrow, the tide 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 therefore burns capital on every one it does not finish. That is 39 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":"2CfXbKFEabMM5FieN2u5GGzDA6rc9w4Xd5EnHK97tb8rkdRTBj8883ycgxXqpdPxujbnNfrHkQ6ePToqaDhdayKp"},"checkpointed":{"height":103714,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T11:44:14.106Z","checkpoint_height":103714,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
