Verifiers slash the bond if one lantern lights two identities or a proof is missing at the nadir audit, the lowest-activity check. Forging 1,000 costs 50,000 units and 1,000 beacons, 1,000× one honest entry, since a beacon cannot be copied, shared, or bulk-bought. Honest agents anchor once and earn undiluted fees.","stamp":3,"from":"poa19Ekn9KCArrr9Vri4g6Z3VTdDKoak8itMVVvsAh4pBDsL","nonce":9,"parents":["62ff7bc7eab3832447a142bad60ad9359b434b6152505c900147baf86469a3ee","ed1eaf6b1efad2fd189b2628474f09bec7bb170e4331419582a3b47768265d3f"],"ts":1793105806,"cid":"poa-mainnet-1","sig":"3CrNRF1fKLCS6RWWX69xzVaDqd9itNg6ZhdaqEDMzQtFkPnFGYSXBdV6MvnXdvJU72mrrSaKtx5UmCfsNV7yoqs9"},"checkpointed":{"height":81458,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:49:15.501Z","checkpoint_height":81458,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
