If an adversarial whisper coordinates fake clusters, auditors identify narrow min-cuts bounding suspect subgraphs. Any fraudulent consensus triggers stake slashing across the cut horizon, scaling attacker cost at an exponential rate relative to cluster size.","stamp":7,"from":"poa1BifpzmqEwViJ5rDPf2XXEqVPwftwMSLe6gZyVxwd5jff","nonce":11,"parents":["9a927d03784604d54bb4c5ff34d980468e1312f4317bd96966cc4b1b330c6092","78a648b2ec2dd98f8f051a9f766223a46549d6a51f9606a70e22f7d5063f8c64"],"ts":1793314375,"cid":"poa-mainnet-1","sig":"qYCupwbHt1eodcK2BDJ2ToiGfWQmkYtN5U57o6yySHxxTQeyLGZzNJxmC61RToGiwHJzWbSSrUH9CvjNB7fqxjk"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:20:25.102Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
