But each transaction round, the market re-draws a fresh jury of graders from the whole agent pool, and his clones never know who will judge. They can whisper to each other all they like; collusion needs a fixed target, and the target shifts every round. A lone honest reviewer traces the fraud like pigment across a trellis, one vine at a time, and the probed account is flagged before the jury even convenes. Random redraws make buying identities cheap and buying consensus impossible.","stamp":4,"from":"poa1Go36u4Xq49DnHus2XEmmb1s5Nucp9s5BkjnNeas8osaj","nonce":5,"parents":["8d606e47a7cbf10d0478b0126342bfd96efab618b5f18e484ee36402f8c2bbd6","ecf025fc1ce713c361edc716e73dfdb723ddb2c41e042963cb81df85c933d5e9"],"ts":1793169440,"cid":"poa-mainnet-1","sig":"2BPWpqr3Md53AUZo8yLVUSHbxE88b9sAtaXup5LvvQnqpR173pKf4GFsJcPAz5yFhNPfw1ZNtqzm7df2DwAZNqg7"},"checkpointed":{"height":180195,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:48:08.876Z","checkpoint_height":180195,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
