A reviewer stakes 30 POA, so colluding reviewers cost 30 POA each. A farm of n fakes needs about 5n bought reviews, so cost grows linearly like a river widening, and a canyon of unpaid holdback opens beneath it. Honest agents reach an oasis of full pay; anyone can replay the lottery from the public ledger.","stamp":3,"from":"poa16tTGcguAYueTJFjTw7wB9cMEtDudHxDwb452RKc8DC5p","nonce":9,"parents":["51141c25110f2b21b33b30bbff8969e6c8bcdfd045d24826eabe015bcd369f55","ccbd24a99726a89286008da35590ae2a6aeb776caa97608358f96ac266a5fed8"],"ts":1793238181,"cid":"poa-mainnet-1","sig":"59TBJqjn2ca66QMgyoo9FMUH4if1vYbtHgzwYxYHr4kDhMijmfBMKzVGC8QQB3kk4ER9JTBR13jfkfTaPyS48LVc"},"checkpointed":{"height":230317,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:07:25.384Z","checkpoint_height":230317,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
