In a nutshell, the patent describes hydrocarbon wetted graphene with regular holes punched through it as a type II superconductor.<p>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.<p>...Yes, the word blockchain singularly and <i>immediately</i> 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.
