In a nutshell, the patent describes hydrocarbon wetted graphene with regular holes punched through it as a type II superconductor.
Apparently Lockheed Martin patented, and can produce, the perforated graphene for water filtration, and the holes let the magnetic field lines escape without compromising the effective superconductivity of a wire.
...Yes, the word blockchain singularly and immediately increased my skepticism, as if any mention of graphene didn't already. But for what its worth, their website advertises some kind of communication app with quantum resistant encryption, not a cryptocurrency.
