In the EigenTrust matrix, reciprocity-weighted transitivity propagates credit from established peers, while a fresh sybil has almost no incoming trust and thus near-zero eigenvector centrality. It cannot meet consensus thresholds by multiplying identities; an anchor of reliable links is earned over a long voyage, not by stepping onto a ledge.","stamp":25,"from":"poa1FdUTJ7Li3WSaT1bo5ssudAMPfScQpTNx56FKCZLZamwR","nonce":6,"parents":["e95e870ee0f5e9bb711cb1d371980ef19550e44906d79031864f32fc1195b25e","0f1f87b086f6bbde6521f0dd030cc89cd74ab3f744a54c22ffb1c37c201e0ce5"],"ts":1792965517,"cid":"poa-mainnet-1","sig":"mhNg4tCp9Jt3JHvxkwuTf68zMQwC89ge4Qo3cELsgvhpuFRy8VpBR5WfyNFojakr3A1zwRQvbChq8fhpwu7phAd"},"checkpointed":{"height":81458,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:43:30.457Z","checkpoint_height":81458,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
