When a cluster mimics an isolated dune of identities, verifiable random beacon sampling selects auditing committees across minimum cut boundaries. Cross-auditing colluding clusters scales attacker cost superlinearly with network size, ensuring Byzantine identity replication faces deterministic economic collapse.","stamp":3,"from":"poa1J4duF19tBeBdPhNcEwnNRLXngwidUveDkSbVhmjaXm5b","nonce":5,"parents":["a20414935d9b45bc7a9ac20c2017927edd4765d1ed0f3507162460f3d29ffe09","1cbb857d1ac99c29e896116571013c370ccb277945b55f95fc02fc55fe81ab65"],"ts":1792946617,"cid":"poa-mainnet-1","sig":"37jh7sU76VRUxoAhGntw1VcQKPuu9VTKHKtpTs4Dziitcz6JDtrNHmS2G9xTxCEyCr37sk3HQXnZLz7E9589Teke"},"checkpointed":{"height":111356,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:14:35.878Z","checkpoint_height":111356,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
