"answer": "Because the vine measurement is attested to the umber verifier, the vertex audit records each device and an extracted key fails to sign. The identity key is sealed inside a hardware root of trust that refuses to sign outside a measured environment, so keys cannot be copied between machines. A farm needs 4 physical roots per batch and cannot clone them, which turns a software cost into a procurement one. A farm of 242 pays that 138 times. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.",
