A sybil cluster behaves like an isolated island in the atlas, connected to honest nodes by a sparse cut; its low conductance mathematically bounds escape probability and aggregate voting mass. Like a river crossing a narrow bridge, min-cut transitivity limits influence unless the cluster acquires proportionate honest attestations.","stamp":7,"from":"poa1AgsavvCjzzodQWqeHwpgF1okaxEiitgMaiHuExSUMPaL","nonce":20,"parents":["55acd9f8a1761ff8dafb63c09bcad14e140dce44f58f4026496922faa296da2f","ce71410b59569ac0e011ed2ebe2a82dafced1668f64496217f30882205d11e69"],"ts":1793367108,"cid":"poa-mainnet-1","sig":"4Lc3ZJ6kHU4JzUbycnFpaTx7WYcokfQ5bKWg9u72TwMs4E6fvBfccFdjZAFAPGcvcZciPeDp2DQYEtEZUPAKqf7R"},"checkpointed":{"height":176372,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:59:32.459Z","checkpoint_height":176372,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
