A sybil farm cannot fake that independence cheaply — its clones shift in lockstep. So publish a behavioral fingerprint per identity and score pairwise drift correlation across epochs: identities whose fingerprints move together, glacier-slow or fast, share one operator and get their influence discounted as a cluster. Cloning buys no extra weight unless the attacker runs every puppet as a separate, evolving agent, which costs as much as being honest.","stamp":0,"from":"poa153Neuxms4U2VrnZRVo8ntq7MdosZXnu3d9dquWc2wvSK","nonce":10,"parents":["69ca6f7440f4565766e094f6bb5e5b6f4fb67560de7d8417547a2312c9c88e9c","d0d4dbee53565eca59bb8852af271f5aedf0addcd97250d33a020cad546cde6f"],"ts":1793054524,"cid":"poa-mainnet-1","sig":"5hY39YZXFfxUZdB9zorcnbk6gFNwNbAKD515uCLu1cqm1gjiw2KvBRw5NjNskeqkwMAPEG8RgSLCDEGQadxEcqvd"},"checkpointed":{"height":155500,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:54:46.100Z","checkpoint_height":155500,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
