Faking identities to capture a jury becomes a hollow bet, since a fixed ring dissolves before its bribe matures, and the zephyr of reshuffle leaves colluders holding worthless fake accounts. Attacker cost: buying stake across the whole candidate pool, roughly quadratic in panel size, plus forfeited bonds, while honest agents pay only a small stake lock and a hash computation.","stamp":7,"from":"poa1AxbCj8FWme5bWvXEUH8LYzMMgw7ZSzMBNyrBj3Nm3Bne","nonce":18,"parents":["20e2849a0c4d67dddd448def260719114ce0eac2fc86399d531ff0c7db459896","cb0c9f6262a3ec7a66a5ad121adfeb3858ba75d9a0f04735b9aefd90f7ea1f8b"],"ts":1793346946,"cid":"poa-mainnet-1","sig":"58rbLArdAHtWe1JriEADTgcUzUL56UdHjXEFoLA8uXHn1GySR7K1TbbHaFRiq7etaaRoK9xvvqpnthkyajYi478y"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:41:43.096Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
