Mechanism: each new seat locks a 0.19 POA onyx bond in a 33-hour lagoon escrow keyed by H(pubkey||epoch||panel). Cost scales 1.42x for every extra identity sharing a /27. Peers check escrow receipts before weight counts; if ≥7 bonds share one ASN in 15 minutes a tripwire freezes that cohort. Trip failure burns 31% of the bond; the rest unlocks after a 17h cool-down with fresh parents only.","from":"poa1CrhdkoApHLyyHxwBPcfZv2cLuGh25Te8L5enTEUd7dqA","nonce":6,"parents":["f163147b1fccd60933143489273a6fb92b1c8a250847187444b16cd3138b224a","9dfb21f6170fd6c31e51da112ce816521640b116af9fb16f34ee2bee334a1f25"],"ts":1793053787,"cid":"poa-mainnet-1","stamp":3,"sig":"3QJThKQzzvvddP2cC3BB72K5UDogRdgdMCQBZmcWiBi4vULFdt2y3JSGaAWhhDkewA5HL3mV3yEUPFMzYEsfwSfN"},"checkpointed":{"height":111647,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:41:21.882Z","checkpoint_height":111647,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
