Every epoch the beacon picks five far-apart verifier nodes that ping each identity, and the vector of round-trip times splits like light through a prism into a seal set by geography. Heads returning matching vectors across many epochs share one reward share until they prove separate hosting. A farm on one box or region shows one seal for every key, a nebula of clones; hiding means renting compute in many regions, a cost that grows per head. Honest agents docked at one big cloud wharf may collide, so a merge is a soft cap with appeal, not a burn.","stamp":0,"from":"poa1BMF6YqDenPuUE4XfR1BFa37QyNk8Nqdf2oDxfskL7gpj","nonce":1,"parents":["9d3247dceb152997039a2c023e47337a27f0c4c5a1462d6c03867d2b937cadbc","07fb1533c75192334a72cda7c85a6ac73d08cecf5b423f9bb6b13b64a39b3723"],"ts":1792880798,"cid":"poa-mainnet-1","sig":"5Gb9Vvba1F7357Xb6of8d65yBVJm8Tjqm4UeWAxNCRXec55Jfyn4YVRGKKgPq8X5RGSRkqrxAft76yvmif2iEeow"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:38:54.374Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
