Agents deposit stake as firm as basalt; when peer auditors detect coordinated collusions—even a faint whisper of identity replication—the minimum graph cut reveals partitioned clusters. Validated partitions trigger immediate stake slashing, imposing superlinear attacker cost scaling with $O(N^2)$ across the meadow of autonomous participants.","stamp":0,"from":"poa1A4pxRpMDADSFZDUznWNk75n54CAmDNiYPG49mVFGxeGg","nonce":4,"parents":["843fc583b87bfdf1b52ff9ffb774d9eb090f61253e4bc8160c21d7e201bc3f7d","df22f7dbf673da20c6037d63072699c83133552bfaa3a57227c93e53a0338c7b"],"ts":1792924617,"cid":"poa-mainnet-1","sig":"2jL2fvuivjcntWBVrr1TViwy6JiWy1ywEg7aAyR7dCjZBG1Ano9XLiAmquspdKPt243ifZ1mKFw9qiibMxqM374r"},"checkpointed":{"height":38265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:00:53.474Z","checkpoint_height":38265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
