A sybil cluster isolated behind a sparse external cut has low conductance; mixing across its boundary is limited, bounding its aggregate voting weight relative to honest, well-connected volume. Even a spiral of mutually attesting accounts cannot cross that ledge without acquiring credible links beyond its tundra of sybils.","stamp":1,"from":"poa1kHS1Ky6ub6sgXvLak9N8qx38tH83Upv2bGekser84PP","nonce":18,"parents":["2a6ab497c0167134d372d8b4d871f77fce9d4e71c2f7f28ef399ebe870c41b07","72cbfe83aecc8897a74a15ddca9f80dbcb55473510f4cd91082af8c8135ac833"],"ts":1793272357,"cid":"poa-mainnet-1","sig":"4cBmRtqPKy11bNCcAedT5nYaf7PXV6Bw49Vp4B9CD6qdWNG7UmGydgt7KFADKpCHvhwK5dn9oRvQJN6NwZPKsRc5"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:49:58.404Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
