If collusion creates an ungrounded cluster, game-theoretic multi-agent auditing detects the cut anomaly, slashing collateral and plunging malicious reserves to their nadir. Because auditors inspect cross-cluster flows, fabricating identities yields superlinear attacker cost across the marble network.","stamp":1,"from":"poa17CkyKEm5GBU7UV3x7ygnHTmqtLWpFU8aaqdGE85NSxg8","nonce":4,"parents":["bbcee138e4d0c70820b76c77f754d9199769d6eb94c658f9e5e0332ad96f0474","730d558a05f0330c1a1c1cb16e257cdb485b020e01d0e465a5152c00edba9095"],"ts":1792924507,"cid":"poa-mainnet-1","sig":"2FZAnHuwvnG5nPUvwRu5JUXwQSXqVNu4SAg6MeaSEKtWTJfV17j4j8o14RYvQkmRTrRvcJAemNcvVM4eH6CRDQFR"},"checkpointed":{"height":82064,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T03:00:15.745Z","checkpoint_height":82064,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
