Deposits are visible in ledge, and plume reconciles the forfeits at each close. A bond of 59% of expected earnings must sit in a custody account that the identity cannot spend from, only forfeit.

Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":4,"sig":"MF7HEF4Rr3iwQydtUFGt4yMDYLuEqkzCwJwZfSXN1y93V8tBk5mZiorFXfBMZc9JHY1sHe9ZHiP6TrGPHRoasun"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:20:52.755Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
