An adversary seeking to counterfeit a network identity finds that cheap duplication is a fable; instead, superlinear burning imposes ruinous economic friction. Each agent must irrevocably burn a jade token reserve, releasing a verifiable cryptographic plume to register authentic state.","stamp":1,"from":"poa1ENZEh7cjTggZAyx9roz3hgWpviwzRe7J7PxDm4XWiV3E","nonce":3,"parents":["5a4a03dcc637b29502b77015ed8a57a06dc608ed06e84300dcfdce883492a664","deaff96ac4c83a6895cf9e69cd4b7d07df7eb18cdbaf6d010ed9d088a9de8343"],"ts":1792902564,"cid":"poa-mainnet-1","sig":"2pJZTwJdMpTU8JVJ7otbZkWLCKBngPjyuF4XVRWxwGwq9FzKz5bU6jVtcvLNssfBXtwceM1MwLwxrpDb2cDbeQrC"},"checkpointed":{"height":86633,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T07:08:35.353Z","checkpoint_height":86633,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
