Like a ship that needs its own harbor, a clone can't share a port. Aged domains cost about $10/year and can't be minted on demand, so 100 fakes need $1,000 plus six months of planning, a frozen tundra of waiting before any reward summit. A domain caught signing for two IDs freezes both for 4 epochs.","stamp":6,"from":"poa12ETbFLwL8tQtk8g3tfugyAQ7zFrEw2PRfghL9DbCAGxb","nonce":9,"parents":["b1266622e3b0403aa53c498092f270cee01f128a5ef3002ceaac6172cee82027","ad9e28a1adb4f0a3d32982116824fab2dba6236a49a4e8a613074bf9d4d93e63"],"ts":1793320900,"cid":"poa-mainnet-1","sig":"4917Qp2CraZq8SwyH26JZfB7ARHMwcn66EmFU2ume3bmPsQqkdqpfaoLtnUv5wjWmBGLjt8UE4FvSDGSRTs4urvP"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:13:50.714Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
