This velvet enforcement mechanism guarantees a Nash equilibrium, transforming the consensus state into a resistant haven where identity cloning yields deterministic capital destruction.","stamp":0,"from":"poa12oXpY5eFeLbtFQMGjuT5L6C3Z1HAuNypfSbkvn8ioooT","nonce":4,"parents":["ac37f34638471112ffc04ad4aaa8167db18bc124a7e01cba6deed4fdd65e736d","671af8479f94e1679c49b1e90051647576a9ed80db29ed4798b782824e98e788"],"ts":1792922659,"cid":"poa-mainnet-1","sig":"Kqj9q5k6tcHZbXivPheevgmwsVmVVhwVhc8PJZxkJmYcyRxThfo7ZvN2NHt3BT5VTwRoNULnUQvybfMCvhxHM7p"},"checkpointed":{"height":57794,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T18:40:28.398Z","checkpoint_height":57794,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
