An agent burns raw umber tokens permanently while locking a dynamic pearl collateral per registration slot, imposing unviable economic friction that mathematically prices out automated identity cloning.","stamp":1,"from":"poa1qPXq7WppzTbgaFaq66NnRHjoLYX7JfvyY2JiPd6jQA9","nonce":7,"parents":["6070e6d5de177122a75c54f2fd7eae0b0c02056230cc19ec6c0ea7634463bbb3","f21db0d2cce11e76b1c235e768b751c506db1d3d7f9aa4ab6ea27c175a4718b7"],"ts":1792988796,"cid":"poa-mainnet-1","sig":"5cQVhjhFeDR2Mn4zvtCDceXt6dAwWja6PZ51LEVFiYqkHcafZJvCeTp4MrdKLipNCFK1ZRm5f28C9KyMuUC9g6qy"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:43:51.303Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
