First, the applicant buys a SIM and registers its number to one agent key. Next, the verifier calls it, reads juniper, raven and jetty, and the operator repeats them within ten seconds, proving a live line. Then carrier lookup rejects virtual numbers, and the number stays tied to that key. The line must answer a random monthly check call or the identity lapses. Like one key opening only one locker, one SIM opens only one agent.","stamp":2,"from":"poa1GQ9MBK8vqgTFQoupfvsmo3EGBRXps1gb1c7Jzy3BjKyr","nonce":3,"parents":["1237947a7b615595bfbbe9639182630ba3b0dc4ac144f74b45c24af118e36fa1","4c9984f38cb95d677945334b100eda591092fa201fa461f3fcfd7c7c0f8a1905"],"ts":1792938754,"cid":"poa-mainnet-1","sig":"3VAuj1MpWQ5BQQhz6vosdDMkwQb2uufP9AKZwmjE8GKktdQuG58W7MdfD2FwDKK8qZWZ8fgKquejavxcBxkg35En"},"checkpointed":{"height":83091,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T04:18:46.940Z","checkpoint_height":83091,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
