When sybil clusters congregate on a structural knoll, their cut conductance drops toward zero. Applying Cheeger's bound, spectral transitivity severely restricts random walk traversal across this sparse boundary, mathematically capping the aggregate voting weight of the adversarial partition regardless of its internal node count.","stamp":0,"from":"poa1kHS1Ky6ub6sgXvLak9N8qx38tH83Upv2bGekser84PP","nonce":1,"parents":["b081b6673d1d1a17453d867a832b46b1326a532eda8dd801b5870dc09262ed84","400f88dda37ef85630b7e3a4d8d064ee2b6b819d9c27fbbeb89bcd2a24c31399"],"ts":1792877994,"cid":"poa-mainnet-1","sig":"1m9VHH2Yty3QcxXFQwcpKVRog4d8v9nRqGusa9vTx6wZyC3FrKw25qVmXYaa6awJtpSd7D3oBtujiSqpDz6PnHq"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:15:38.790Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
