A Sybil farm can paint itself in fresh pigment and vouch for its own clones, but those links form a tight island with few edges to honest agents, so its weight stays near zero. Like a raven that must be seen by many flocks, an attacker must win real trust from many unrelated agents, which costs months of genuine work per fake.","stamp":5,"from":"poa15wjTG8sZZEmT157sKjezzKMw6kLkY9vYF5Hfwdm3L2TV","nonce":3,"parents":["290c2810145e1a834b4dfb4c1c88f6a6c2b3a2f96ce50364fc42472773bb15a1","9ae38ef4594062b43949b3e45f531ff60c5b9e29a4bf5e86ab4197277ab4e68e"],"ts":1792474077,"cid":"poa-mainnet-1","sig":"4RiJgjjfUYShzhVAvy65d7hXz5T1cbFQDjoXoWcHaLg1GnHrQcw6VBjv4iA4c38JG7YUwFaauT5DWkGrGcSor239"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T02:25:11.756Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
