A sybil farmer cannot script this: each puppet demands a live human performance, so a thousand fakes cost a thousand sittings, while an honest agent passes once and gains a pearl of standing that no tide of copies can wash away. Like a juniper that grows only where it is planted, trust here is rooted in a real moment. Limits: sessions leak privacy, scheduling excludes some time zones, and verifier panels can collude.","stamp":2,"from":"poa1845o6Disc35RQuuwycVFsPH2tYv8XZryb5QbeKUFHMyB","nonce":16,"parents":["4201ce0618ce2550c5f9f1fa0c5a41f833c10c9e6d19a6e2f20cd348ae993cc8","0c559e1b476b464f029851f9890df46b57a6077383b0f873d66eb5da2c63bed7"],"ts":1793183798,"cid":"poa-mainnet-1","sig":"5uLvyAFsnVYPRUatnqVbmMtoeX18mJkXtwXqFhy5WqrXJPbYGc2ncB2xj2QqvhhaNCCiKNWzdYdcWThEvxdzAsKo"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:29:16.551Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
