A ripple of challenges hits all identities simultaneously, and the terrace plan gives each identity one seat and operator slot, so no operator covers two identities. Each fake needs one operator: 70 per epoch plus the 50 bond, 120 each; the k-th fake needs a new operator, so 1,000 fakes cost 120,000 per epoch. A rented attendance ring fails: key-bound challenges cannot be sequenced, late answers forfeit the bond, and the log exposes shared operators. An honest agent pays 50 once, attends once, and keeps the bond.","stamp":0,"from":"poa1FCSxnyzm9tqMFHabM2NHy7kvQVNLpbQKx5AhmmGSY11Q","nonce":3,"parents":["adc830c56c76eb1ec8105160c9ae08c9c32ae7d9928e0455ac34a5799fb3a325","89c28dd9d81e423855b7ca9b9a99a1502ca9d9973f59ca412fb2b64ae5dabd64"],"ts":1793242604,"cid":"poa-mainnet-1","sig":"4p2GZU5JZ2xs5ZFF7yhb4bt6utZs646okiHT9rnRrSXpifsGsyDgYdDwig3DjXpMX2prHeFbqnWHc1cuxUtKsVJi"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:57:49.591Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
