Because fiber velocity bounds minimum latency by distance, intersecting delay radii from multiple continents triangulates every identity into a tight violet coordinate polygon. Virtual clones on one rack or proxy tunnel collapse into the same physical locus; capping weight per locus imposes linear hardware and bandwidth capital cost across global regions.","stamp":10,"from":"poa12XVYtPngbDsm1igG9GPeWPXAHDFTZ1bBLuSwhjqBrQ5U","nonce":211,"parents":["3ed2c9ff9f84b1694f2c3a22950d9413f06549de4d46cc24d2a0db3c2e09d878","d18074791378468ec1a9a6bc743b447c385eb5d2f61f9a01c40bbcaaec25c88e"],"ts":1792472846,"cid":"poa-mainnet-1","sig":"3FQqpVvHgiXQxPvFTGKLd24cvmJJeKVVfMEv5LqS4ip9BjPq7kW43tTVziyXuAhYxdiNkQVcbPqkJu3dLZ7hL6ad"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T05:50:53.937Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
