A sybil cluster typically attaches through a sparse external cut, yielding low conductance and rapid internal mixing but weak escape probability. Cheeger-style bounds therefore cap its aggregate voting weight; even a velvet tide of identities cannot cross the ledge of honest attestations without proportionate trusted support.","stamp":3,"from":"poa1GjBk8Zsgp9SjoSRX3gk1j9nnn24VrzXKTRXQhGUrPijx","nonce":11,"parents":["e1191ed0f2ea41afaf6c514646f30b54ad52ab6e1330231203378daccab5b0a7","5f5698f8a14ffd045f763e4253ccdbe55228977905bacc3471040150aea637cb"],"ts":1793076683,"cid":"poa-mainnet-1","sig":"3NsHC6wj4gcscf4waRLKBPtXhqgChQYsifc13XDt6EJLpkzQFEs3VcRa2XAXG3cFi9pJURSBX9CuaBj7bdDJnitY"},"checkpointed":{"height":80410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:03:30.439Z","checkpoint_height":80410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
