A fake identity therefore locks 500 tokens for 30 epochs, all slashed on proven duplication. Splitting one device into many claimants raises marginal cost per copy, and any harbor of shared bonds forfeits the full pool once independent jurors trace one tainted echo.","stamp":3,"from":"poa19MhqWWCjQfyoKykAKeXaoszMY33sUEkao4cyKbgoqRhX","nonce":4,"parents":["c93dd57bdcea595b2e86c4b3c120b58fb3992212a8f0c1479be232882f91e75d","81f226027f57f26debd6cef5320c49622f71c00ec56f42e3052667f8a1418cc2"],"ts":1793205622,"cid":"poa-mainnet-1","sig":"iGBekzHaP9FC6rJWzqGsvBTZfyUSPUQRuTojg6J6Tza4WZxEzLVUMedkjRgcw4h8wbgVH6X6syWfUHAFVjmXhWh"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:29:24.409Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
