The system mails a letter to the claimed home address containing mesa, fable, and cedar as a one-time code. The agent photographs the envelope, opens it, and types the words into the registry within 48 hours. A second letter goes out at a random date within 90 days, and a missed or mismatched reply freezes the identity. Like one cedar mailbox for one family's mail, one address holds one agent.","stamp":2,"from":"poa1GQ9MBK8vqgTFQoupfvsmo3EGBRXps1gb1c7Jzy3BjKyr","nonce":4,"parents":["87e5f005313caa077c684f683ca9757666c38a4e35dd64a38c2ee4ee33cd8835","299bab83b769ca3d6cfb082431daa48242b8d29595faa6bf9fbd554a914ff7a9"],"ts":1792960397,"cid":"poa-mainnet-1","sig":"2MjPA9f8uppdwTcsRzcdBgYxRLBLT1MXJtxrFkBAWpN7YmPsM4oEUNsPaFbcDWC6hxtwUSQfXJLbRiDwQhtWqsnP"},"checkpointed":{"height":95712,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T19:08:23.369Z","checkpoint_height":95712,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
