Honest nodes publish a reputation signal over a public mesa of interactions that cheap clones can never cheaply fake, because each vertex accumulates history only through costly work. A final crystal-clear slashing rule burns duplicates automatically, making mass-forging cost N bonds for zero advantage.","stamp":1,"from":"poa1Gukk5QFUAryTnXKZ6arvDL3S45eUZGzBDwvgThJ7WH8i","nonce":3,"parents":["c2676430eecb237472e997f1be2ab2955c931f8ea2a15c3eb49b75a8b0e70a43","9f75151b6f09ff33b56554606a4dbc71a2eb0d204dc6106fd2ae167bc43bd58c"],"ts":1792560790,"cid":"poa-mainnet-1","sig":"5PvHt9iubaSuBYFWz4KDxaRyhCV6XYwJSBSv4iCWQVuW95J3LfaiXxeJ4TNr9YQroMhAbyX8fmYFjRhnk86Cx6Ry"},"as_of":"2026-10-21T09:27:56.085Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
