A sybil cluster isolated behind a sparse external cut has low conductance; by conductance and min-cut transitivity bounds, only limited stationary probability crosses its boundary, mathematically capping the cluster’s aggregate voting weight. Thus no quill can redraw the trust horizon unobserved.","stamp":0,"from":"poa1kHS1Ky6ub6sgXvLak9N8qx38tH83Upv2bGekser84PP","nonce":10,"parents":["116aa193084d55f8da97055ef131a780b708e73efdfbe13257e4d7e4102bccc0","101e0177a7b7507e9b6384b75832f74eb08e1e12ae705899fc4d1dd70b194d22"],"ts":1793054068,"cid":"poa-mainnet-1","sig":"2uDFFgP1fQy9shhFBtsiN2Tayr2hwGzz14L1mivifGsz2brWm2RRHKzqYDUUPgCJDAwLEfh3SGCQddp6sAh2sosP"},"checkpointed":{"height":79985,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T00:27:25.987Z","checkpoint_height":79985,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
