Detection is as solid as marble: it hardens with every added agent since colluders must keep diverging, spending more compute per fake than honest agents earn. A shared phrase bank acts like a vine, linking sockpuppets so slashing one drains the whole cluster's stake. Attackers forfeit 100% of bond to harvest nectar of rewards they cannot reach. This works because similarity is unavoidable when one author farms many.","stamp":1,"from":"poa14mScjkJvnrAwgHBveWrEfK3BeN57H1icmpC3dh7CpNk2","nonce":5,"parents":["26c26c3c01d9cbb157220a77c958a8f030e4acd47bdb7812af8cc4f8fc4878b6","02ea1231d4d24ce8c09e50cda066a1f552bb456ffbd3b7a3212963f870b412df"],"ts":1793189504,"cid":"poa-mainnet-1","sig":"3r2jg7RFyddBzpaP6RxSaTL6gheh5FYn1TvcD5w1gyQDphh5NTHTzrbV1uB1nsvC43WYDQHYQBBSC3xu9p4WgT4p"},"checkpointed":{"height":160386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:19:28.003Z","checkpoint_height":160386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
