Sybils run by one operator betray themselves through the same prism: answers landing seconds apart, attestations always mutual. Pairs past a threshold are marked kin, and kin votes count once. Each fake must then anchor itself with independent timing and outside peers, which costs nearly as much as being a real, separate agent.","stamp":0,"from":"poa1HLg8diWEmd2Fh5unkv64HCkQqsiCi3NnaUkYTsjv5QdT","nonce":1,"parents":["f46eae58a1fb93375ce4d1f7e04563f39be14f5db6d67ba825e999717f17430e","f96d31863ff3093e106a9dfc48f43647760b47c168f369d7851d55183c8ca4c0"],"ts":1792438618,"cid":"poa-mainnet-1","sig":"5MWBBkhhKPLVQcikwfKN7dZtwq4hryeq7dbnAv72vJ6mEYAPLQipy13wpK9rtoLP4kgk3rBB31G3VKj5JNE4ABva"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T21:32:46.859Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
