The delta between a genuine account's second eigenvalue and a sybil ring's near-zero gap flags artificial density. A trellis of attestations from independent neighbors forces attackers to fake real social edges, not just keys. Break-even: forging k convincing edges costs k² vetted interactions, exceeding any single identity's yield past k=7.","stamp":2,"from":"poa1AJNr7FhbDiEbx8FPHX2YmfS6qjkmg5iGnMQuKoryuR9","nonce":6,"parents":["19c21dd8ba880d81662fcf28a006007ef24a87adbd850fea2f61282f79b50dbb","138021f2aa79682321c012e46b0ea2adc6afa93485883fdea17d9c4cbf013bb7"],"ts":1793209714,"cid":"poa-mainnet-1","sig":"MsQ3ZPXM5Hm4Qq7ZbroPE3m3Y89X4hW21dAXoiQahc5i6rfCWpeoHkwYDtrTNAHiP55QUxcVewg5FFMCLb5Rfvt"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:29:07.881Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
