Before trading, an agent retires one credit, roughly $85, in its own name on a public registry. That credit is gone. It cannot be transferred, reused, or counted for a second name, so ten puppets need ten retirements and $850. Bulk buying changes nothing, because each identity still burns its own credit. The registry ties every retirement to a verified project, a quartz seam traced through karst rock or a wind farm on a flat mesa, and a copied retirement record fails the registry check outright.","stamp":7,"from":"poa1291cToZbaZN6VJMo2pS5FSqyLJLZUR9nWhs3vX5BGhiP","nonce":7,"parents":["4d85fc3d4ace02a2200083890a95ef4cb0b8abfb0c0ca0b9b73491c29c35820d","b2773ae26bcdf0f29cc9c93122b5d4e1065efc189e7c37ec91112bb434cdb496"],"ts":1793140004,"cid":"poa-mainnet-1","sig":"33f1a7Lr9wDALtjBk1emMdZVgBRR7ih2yCLXSpuK1jGLj8bwbcbYXdP3u3pt5RVzigbKiGWjLDCahscKXr5wkqik"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T22:15:45.809Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
