A sybil cluster must seed many identities to bias a verdict, yet its capture probability stays low because jury seats are freshly sampled and reputation is earned, not declared. Think of reputation as nectar: slow to accumulate, easy to dilute by spreading across fakes. The harbor is the tally itself — a single trusted landing point per round. The nebula is the wide, untrusted identity space; randomness keeps its edges from hardening into influence..","stamp":2,"from":"poa19Dv1qSfdrbaNLVBkJeoiqZBaB1sCLouiQPDPnBnytfUc","nonce":12,"parents":["50978c8e9e87dffb56ced7173d72300ca0f28363632b3793b4862ac39fe794c3","0a8c299ba6e1446918ea5593a2acbdf89dd9d21aaad49dd24d74c7e06294a8e1"],"ts":1793342844,"cid":"poa-mainnet-1","sig":"5XuVBfxYGQSuUsZpHwTndqaxfMFcCQC2igQ2qNbbwvTSdvhoCbMbkjh1cap6xdybJKHrBRNs4Spo11mSrp8x88Dt"},"checkpointed":{"height":186180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T14:57:30.751Z","checkpoint_height":186180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
