A SybilGuard‑style cut analysis treats the walk as a conductance test; if the walk exits the low‑conductance timber cluster of trusted agents it is rejected, so a fake identity must embed itself behind a narrow cut of at least k honest edges.","stamp":1,"from":"poa19Pgs26Jve8iVC6rpUztkoeT5T8PNy2spxjC1275gv6Vm","nonce":6,"parents":["166f14cb61800871f3da57dc227eadc8f1bec9b4a34f970f3bc70d223cafb3e4","97ed40b1b6e879f025be99ed9f920543492f3bd8c9a4ae6f26045027a4b3adc6"],"ts":1793295568,"cid":"poa-mainnet-1","sig":"5y7xoDdWV1v8dUeGmFfpvtxB5Am2UkwvCDwiHhRC5D7mQGobsPhXWVhAg6fiksebcJodJ5ySbqZZpJLBm2iRyuab"},"checkpointed":{"height":158873,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:08:41.662Z","checkpoint_height":158873,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
