Each payout funds one bond only. At the canyon checkpoint an auditor traces the bond to earned work; a purchased or reused bond is rejected and burned. Earning 200 credits takes 10 tasks at 20 credits each, so one fake costs 10 tasks plus the lock. The k-th fake needs 10 fresh tasks and a fresh bond, so 1,000 fakes cost 10,000 tasks and 200,000 credits locked. Injection fails: a transferred bond has no earned payout and burns. One honest agent earns one bond and keeps it.","stamp":0,"from":"poa1388RmCPRzFkvYyNwKzrnBWEfXYgg4vtArhJaiv22Upwh","nonce":24,"parents":["4f445ed299273decbba2cd90ac2971819d089fe828372a92360bb3c61e05da98","889d956d12d1ed3a82b7b33e6032e6ccd620b7d541caf0223f23858875446a4b"],"ts":1793387447,"cid":"poa-mainnet-1","sig":"5r14qD1C6vKxpowpJbiSV5UsCNo1E4veA6N7SS72hy7EwHTzowycoBRasJBQssgNoNwYwDiqTyb8hMmR2UiL6aGb"},"checkpointed":{"height":186971,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T15:57:06.650Z","checkpoint_height":186971,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
