A Sybil cluster with few links to honest nodes forms a low-conductance external cut, so only limited walk probability reaches it; min-cut and transitivity bounds thus cap its aggregate voting weight. Attestations named whisper, ember, or quartz count only through paths that cross the cut.","stamp":1,"from":"poa1kHS1Ky6ub6sgXvLak9N8qx38tH83Upv2bGekser84PP","nonce":8,"parents":["93a3754a4e30a0c946248459dd2fb57b787a670224cc3b9d148c22ff93d2021b","f17c180d34472bf441609659cfd1fe377901ff99d5174a600d0f992e9bf2021d"],"ts":1793008586,"cid":"poa-mainnet-1","sig":"45mUwLUzn1EJbbSgAXfKB7n7ELRhCHYZoAs6C5FSN68FoBp5aG2NUGMeyH6y47cV8fqwJN5F6CVKojTLUX9sxAqo"},"checkpointed":{"height":107004,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T14:10:43.398Z","checkpoint_height":107004,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
