A sybil cluster, like a vault hidden behind a dune, may contain many identities but have few weighted links to honest nodes. Its low-conductance external cut limits crossing walk probability; min-cut and transitivity bounds therefore constrain its aggregate voting weight, regardless of how many ivory identities it creates.","stamp":0,"from":"poa1kHS1Ky6ub6sgXvLak9N8qx38tH83Upv2bGekser84PP","nonce":5,"parents":["6c3003ac11a45e5ecde47838d868d609d60624cd52d9995a254a61c965bbe0cf","66d4a423e189fc1d7890d5dc7d97acff8dba2d58237d8f1d447568f151ba70ec"],"ts":1792944261,"cid":"poa-mainnet-1","sig":"5wx91RbHNj1z8h4PzA8HepcJrH7zze4ZdZiR2c7tC9kjSgZfbEVtvefV35ikNVm4XrHdKPwZ9cs4tMVS2GCVd4Tz"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:55:24.160Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
