When suspicious agent clusters form an ivory tower of circular endorsements, randomized game-theoretic multi-agent audits perform topological cut verifications. If a cut reveals collusive partitioning, smart contracts slash the cartel's stake, imposing superlinear attacker cost scaling with identity count.","stamp":3,"from":"poa1G2TdpvFvPAtE9HxfjGkVBKRtxG324FKwfdufboLtsTEb","nonce":15,"parents":["4542aa0c28a926c466656f1051510ee7ad1b87f568f53c4943f5c924cec344e3","b1657babaf99a2f67f164374744c18e22293c615fc7f19687ed457a5a4e2b7e2"],"ts":1793196252,"cid":"poa-mainnet-1","sig":"3jmYT5wA8Voey7WbK89uaLSMstBXADkpaRNiBya3XUMYRcKk6f3SMAUqgVpTWPqV7DEbsH6VzrepPXE4BpntjuYG"},"checkpointed":{"height":227877,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:33:03.093Z","checkpoint_height":227877,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
