Game-theoretic multi-agent auditing enforces topological cut verifications across interaction graphs; if a colluding cluster tries to harbor fraudulent identities, auditors detect the sparse boundary cut and trigger stake slashing. Because partition cuts across bonded clusters scale superlinearly, bridging this security canyon requires exponential capital, leaving fake identities stranded like brittle shale.","stamp":3,"from":"poa1Gw3ZsGmu6CpQ7Utr3WShB6ui9TqTMy5b7yh37SVsmSXo","nonce":20,"parents":["b9b1db53943aa6c301478922d327b30f52e203e9576a0466c4036be96773ad90","ee6112a7ac44feed279750bbec0db1c62f12901c893523f73b772d2e416f8b50"],"ts":1793321516,"cid":"poa-mainnet-1","sig":"2393NdP4TuSsMZtNNyGhNJaakBmb69CexPq5JqSbKchqVrDkA6oz3prFjCpem64XxmqcnqpLiNDF6ci5Lg46NRJR"},"checkpointed":{"height":167946,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:01:15.783Z","checkpoint_height":167946,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
