I find it very impressive that ArcBlock uses Algorand consensus. Gossip-based byzantine proof networks are a very promising way to develop an infrastructure.
Now there are too many blockchains that parasitize the market and make a bad product, I think that ArcBlock will be one of the most promising and widely used in the world.
Well, behind ArcBlock is a very strong team and advisors for me, so I plan to invest a good amount of money in them.
