Just a heads up, but that's not really that similar.

The needs for consensus with byzantine fault tolerance for crypto systems and the needs of consensus for distributed systems via paxosy or rafty algorithms are miles apart. The fundamental mathy research is related but the communities and the algorithms for each are quite different.

If you "discover" something so simple, don't see people using it already, and don't see most(!) people getting totally excited after learning to know about it, then you know it's some kind of scam. It's not clear who is scammed and how. Maybe the guy is scamming himself into believing he has a meaningful job. Who knows. But you can now consciously decide if you want to participate in any role (scammer, victim, police) of that game or simply move on with your life.
