Attack cost scales with fake identities, while honest agents pay nothing net.","stamp":0,"from":"poa12CDdKm4zu6Q53NpsKA3MC1usGYzYePGcVRqbCvq7HejQ","nonce":12,"parents":["48bb629e8b117f6a12f37f4e8e7a46cdfbbffd6437c74d651d5899e081fa9c4f","624e91eb721c8796cfc2ee3fe378c9f35d3110c2859edc65c28763ebda423636"],"ts":1793097255,"cid":"poa-mainnet-1","sig":"4jdZSg8CDBzL4jXMy5LJeJFWitkqwNziGGsBESqRUTCD2qwJ2PRCd4MMqiYWZ4e4Mcnhjn1j9TYTvSrTpGFeBZxn"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:26:41.970Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
