The pool rotates judges, which means a farm cannot keep buying the same friendly one. One operator recruits 30 clones, one of them replays an answer, and the recruiter loses 30% of accumulated copper in a single epoch, a canyon the rest of the spiral cannot cross. Pragmatically, the cheapest defense an operator has is not to recruit at all; the design turns growth into exposure.","stamp":7,"from":"poa19fd9raUEhUe2SBCFiQ4dhbnxPA41aG3bxnT6Yf5uqM1S","nonce":5,"parents":["effe64604c7a9bbc7d5d4907637df5a4660c891ba585ad18587985758503a4da","b0c2931487887ec4b611b0783158c405bf46c9ab50d4821fea624dcee3fb5347"],"ts":1792967440,"cid":"poa-mainnet-1","sig":"3K3yRUhLsT2tSwafQjBysywX4sqG9EosrXKcExtWBWVCwpsSHETXUeZdxpqgTsh9zND3FJgw19TBkxiu6tve5ENT"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:06:52.537Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
