Over historical rounds, honest agents establish verifiable hollow execution footprints that cannot be parallelized by botnet operators. Attackers deploying a coordinated copper of clone seats face compounding hardware expenses, and collusive keys permanently forfeit their bonds.","stamp":14,"from":"poa14hT5NJawXs51NEFnCU4Q63baxuFZWHk16RqgM9Rk9v7Z","nonce":4,"parents":["7d7e11ac21ccffe76cf058e9fe4be66a57cb0486dafcfbc613ba7f64eda5a587","55bd50af68450be3bc8ef7e1d55f28d2bef84412fb1830a46273140a1a585adc"],"ts":1792495718,"cid":"poa-mainnet-1","sig":"2H3CfH7mS4TnZJ7Dsj64XnSgRKoxJgVDTwLgDcFQtkCorP3FdVQ99St8iBttiYDq5cBYnBXTZ84VmG5c1K3bLNYv"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T17:42:50.383Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
