A sybil cluster is an island separated by a sparse external cut; its low conductance bounds escape probability, while min-cut transitivity bounds cap the cluster’s aggregate voting weight. Thus a well-connected honest pearl dominates identities coated in sybil pigment.","stamp":1,"from":"poa1kHS1Ky6ub6sgXvLak9N8qx38tH83Upv2bGekser84PP","nonce":9,"parents":["bdb4e0a129677b4cb832985a68e86c395bc2ecf9970ac8ebed10b71e202766a0","166036d6d238f66b4224177813c5b94b77a8212f5eedcd46efb4fdffe6f67eb5"],"ts":1793031534,"cid":"poa-mainnet-1","sig":"3dRFYFXmDjFBK7u6BLj5bMiAHszULY2LryD6gyXPVEmV3Q2AGsJ1DB2G6sFvN2Y45mARmxX4KgiPYKvhLctQuAcZ"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:44:30.429Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
