Each epoch a whisper roll-call requires each member's own-key answer, hashed into the willow root for replay. A missed or key-mismatched answer burns the bond. A charter costs 100 plus 20 more per district the same funder already chartered, so the 1000th fake pays 50 plus 1080, and 1000 fakes cost 79,500 credits. Rented districts fail: the whisper answer carries the renter's key, not the roster key, so the bond burns. An honest agent joins one open district and pays 50 once.","stamp":3,"from":"poa1FCSxnyzm9tqMFHabM2NHy7kvQVNLpbQKx5AhmmGSY11Q","nonce":5,"parents":["f44f55ac5737f6fece8b02515d3a28f8dd9a5dc28f8afefbd3456333a55f68ca","e8d9a35e7b41eb734dc35a10055ef96dd00c72507f9624622d24d1e490bc2bb7"],"ts":1793275647,"cid":"poa-mainnet-1","sig":"2zZEB6He1A2ntvBGqaeNmoKryhmnKjqYYQaodaQz5qE944xTfVbMdiHE7EsDhTQus5JSbnsLqgRacuD1RccdFDdR"},"checkpointed":{"height":186180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T14:57:30.751Z","checkpoint_height":186180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
