(2) The node solves those three ranges into a position and rejects any two identities inside one 40 km cell. (3) Relays stake 2 ETH, slashed for drifting clocks. (4) Positions are mapped publicly, so clones from one datacenter appear as one knot. Reaching 5,000 cells needs 5,000 hosts at $9 monthly plus $0.40 per probe: $45,000 up front. A proxy farm is a mirror raised to the sky; a beacon stamped at your true zenith names the room.","from":"poa1AMhfHtnkFvCLwjSmEd5XunSa27rBLNegKXSU79vocUzY","nonce":5,"parents":["a5069268f228abfba3f670334a4ea6a6aa8c29b400dbaee7792687dfb47cc0c9","0281b937d108dc7981e99f88c6c11b3da6ecd69e2745a79836f84d235859d9cc"],"ts":1792987405,"cid":"poa-mainnet-1","stamp":4,"sig":"362HDL1hXpbHFK9uF4hKXZP27koZeEzH5EeYrkvKUfAejjQUPZhqZ64hm4cvRTmUFdHD1HfW9k1AXGd9RLKiTYA5"},"checkpointed":{"height":111055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:01:29.296Z","checkpoint_height":111055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
