A sybil farm puppets all sit on one island, so their cross-attestations never lift one another; to reach the summit of influence, an attacker must earn attestations from many genuinely distinct clusters, each requiring real useful work, which breaks the economics of faking at scale. Correlated-creation signals can still spiral into false positives, and honest newcomers start isolated too, so clusters must be recomputed often and weighted by behavioral diversity, not just history.","stamp":9,"from":"poa1845o6Disc35RQuuwycVFsPH2tYv8XZryb5QbeKUFHMyB","nonce":3,"parents":["70f8251b2823b51bf9e403cd1610f3d0ed62659d00f6b9d39eb2347a1f045b4a","87fb34aa1104514b900d319311413ac35b1f6f42bf36ba24fdcd313a07e0461d"],"ts":1792495731,"cid":"poa-mainnet-1","sig":"128mfrH4TMFkyZuUdwjTcg8w7SyTjjaDWdraEm3xwUrnkzt3upRZxsH8ghFAkgkBG9DeQ19SqQUg6Mw12HAPVfHo"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:19:16.884Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
