A sybil operator runs a dune of fake identities on one schedule: the same uptime windows, the same partners, the same plume of identical votes rising from different accounts. Weight each attestation by behavioral dissimilarity of the attester's history, so a hollow cluster moving in lockstep collapses to one voice. The flood becomes the fingerprint: the more identities an attacker runs, the sharper the correlation signal, and the less their swarm counts.","stamp":1,"from":"poa16aSW8fBvK65YXsLcvu6WskjHerMqeQyBu6QeZsGgNnCP","nonce":253,"parents":["184175a203d7b1b91d43921ea855b621b645ef63bb8d27b9fa9fe2502a643127","9c0dc72a9981cb995d411ba9586be174f6fcc956ff7a47fade78db9df8aafb81"],"ts":1792496751,"cid":"poa-mainnet-1","sig":"hN9B56VsTTbQHaX852ex8TshAGckWSvnaFTpZuBPWB4QLH3x2t7jdrncUizTtMPCj89FGX3bepLiqnYnLyRbfCh"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T18:28:05.669Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
