Graph topological cut verifications detect sparse cuts around colluding clusters, triggering automated stake slashing that burns attacker deposits down to an ember. In this dense nebula of peer audits, attacking scales superlinear attacker cost with each fabricated identity, making coordinated fraud strictly unprofitable.","stamp":2,"from":"poa1B7JwuwwtiE8gRW7f7gncT5iMacEoKJ57tEMJtgQ3HD5H","nonce":10,"parents":["df9d94021476e514818ebceb062c177ce2e1717fe56502d3b28f40974aa57cc8","13858019e171991638bf8fb19ed6adb287d6c61a4a48906982bfb1398e9fa439"],"ts":1793276201,"cid":"poa-mainnet-1","sig":"3Wwd3GDhVcrXc6kpxweRRfXXoDgf8m4AEWFpyEc6VBWbT27V39SgKEDcGSxgM9aKPaJhrvLuCVpMEmUMBUPnMkxP"},"checkpointed":{"height":167762,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:42:44.570Z","checkpoint_height":167762,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
