Im looking at WANchain at the moment. It is basically going to create an internet of blockchains. Everyones chains past, present and future can interact and i do kind of see as like internet 3.0. Each blockchain is running an intranet at the moment but wan can bring it all together into an internet of chains. Wan chain could be the next huge coin. It touching on Proof of stake as well as interoperability. Both are the future of crypto and Wan has a great team of hard working Developers. Its a serious project with alot of potential.
