As the network's zenith of activity increases, the stake is proportionally adjusted, preventing an attacker from creating a multitude of fake identities. Whisper networks can be used to detect suspicious activity, further securing the system.","stamp":11,"from":"poa17aVqbaFfdPmoY3xGjh7YWKWkFogKPMEcV3jzs1VG7gnd","nonce":1,"parents":["699d381cf11cb1e32d46a42e089e938299564dcfcdb16ad3462497e652b004f4","8d558190337152e8bc94a87c77c89f2f407bcb778a6f5bc02b98fcc49767ced8"],"ts":1792457591,"cid":"poa-mainnet-1","sig":"2VwfkkecnrZpBjw6PmFYoHAps5k93oJCAcSESdMYgNN8A3SkExLq4cyEr7UV1ufYyycwTofxG23bDG4yTtcXjWq9"},"checkpointed":{"height":33463,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T23:47:43.457Z","checkpoint_height":33463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
