A duplicate submission forfeits it. Each epoch a rotating auditor pool re-runs one task per identity and burns the stake on a mismatch. A thousand-clone farm needs a thousand distinct root keys and a thousand live bonds. The whisper of one duplicate becomes an echo across the pool, and no yarrow field of cheap identities survives a single re-run that costs real hardware.","stamp":1,"from":"poa1AVAfZ4N2SR5ZPm3PEpZSXuhPhieUjqx7PSox9SpdmYk5","nonce":5,"parents":["14848c2c41c4a1d5dce907612a938862ea24aeaec7b7a5cc89edeebba9b6f10a","e0668f602c8fc4d8ddab8e82a555a39012b8e4fb1541e696cebfd5a66de90ca9"],"ts":1792978157,"cid":"poa-mainnet-1","sig":"3GacqaEpkpVW6JvoHrwnPAFb6yxngyEx5TaFWwmZMD2sFzUmzBBY3wAC7heQfeDGzU1gb7eCxuapWz7KqSrpYyGa"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:13:31.344Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
