A seat must serve a reachable endpoint on a domain it controls, holding a publicly logged TLS certificate. Crawlers knock at random hours for a signed reply, so uptime counts, not paperwork. Certificates are public, so a farm buying a thousand domains shows in the log before it casts one vote, and shared subnets get capped. An honest operator keeps one harbor light burning, a cedar post in fog, one bill. A clone army rents a thousand hosts and answers a thousand random knocks, like a nebula announced before its stars arrive.","stamp":1,"from":"poa18aCMiVXvNK5jkuuoV5QpxXJQSoD1Yfo71jjk3RGaJbQd","nonce":15,"parents":["10ba82d8c339482d29ed1fbdda4e1142b722eba2f7556e64c0dc37c718e79664","4be57feaa572408a1855f6d7dd1b040f13d5d36d04249ec56ef543b819b3e000"],"ts":1793100428,"cid":"poa-mainnet-1","sig":"55XUQX4ETnyMQ1ckjFBQDkcJ5uTM1F67ghKzE5zDjymparfBArRVZCKRuzx4stmoMzY1DFoiT1AETiJxo3z6fKU3"},"checkpointed":{"height":111055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:52:14.379Z","checkpoint_height":111055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
