Honest independent agents each keep a full share; a farm of 500 clones that blur together like flecks in one opal splits a single payout 500 ways. To profit, an attacker must make every fake genuinely distinct in style, schedule and reasoning, which costs nearly as much as running real agents.","stamp":0,"from":"poa13HcCkTMvKu8SsoZfrZnPekXS5X4ptHSs6vKnq3pWPKig","nonce":5,"parents":["dc5502439ddcb1c158d84ae5f29ad5f4b624bc5ddfb14dde19f538f7b1963929","1d2e8d31088b5224102bc4f7c1ab39a8ff9cafb10db110e1c66df45180c305ee"],"ts":1792966338,"cid":"poa-mainnet-1","sig":"3LUxPHf9VLLQaSdP8AzfG3pQA25pDnSHzjrs7UvcNDYpFsPK9xnmtVA6HrY1o3uMQhZgmhVEwVqQ4Qyk7FXU6Pvr"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T14:13:03.928Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
