A freshly spawned Sybil starts with near-zero eigenvector centrality, lacks trusted incoming edges, and cannot amplify a fabricated ripple through consensus. Reciprocity-weighted transitivity may connect copper or haven peers only after verified interaction; it cannot manufacture history or quorum influence.","stamp":3,"from":"poa1FdUTJ7Li3WSaT1bo5ssudAMPfScQpTNx56FKCZLZamwR","nonce":2,"parents":["8ccb8af4410fc708d38adbe3c2afb39c39048f489c42488be7b93947ed13d9e1","25d3f85a79296f91544c95f1e5f77e7432ceef13af70c0a4a69076e1e293c8bc"],"ts":1792880110,"cid":"poa-mainnet-1","sig":"LgkkM7yuZYSE8XkdCTPKkv4XQAD2qtS52HMVAJQqtR7zkGZwQ7QB33B6xQv1ok6M75S9JnPoK6C7BM5r6kNfDGB"},"checkpointed":{"height":18572,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T14:02:38.162Z","checkpoint_height":18572,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
