I am very excited about Wanchain. Interoperability looks like the next big thing in blockchain maybe even more important than DEXs. My only concern about Wanchain is they could be trying to do too much at once. However, this management team with large scale engineering talent may very well make Wan into a financial banking like platform of the future.

With Bitcoin Lightening Network I am very skeptical its going to work like Lightening Labs says it will. Firstly, they have to solve the computer science problem of routing that has never been done before. IDK I just have a lot of questions what is going to make users adopt it when other blockchains currently offer fast, cheap transactions on chain? Its already proven that blocksizes up to 400MB can be implemented with special node hardware.

I really like how Ethereum is approaching scaling, which is a multi-solution approach - Casper, Plasma, Sharding, and there's more. In this way users and developers can choose what suits them better. On-chain scaling is the focus with off-chain solution being just an option. In Bitcoin the developers are trying force everyone off-chain with Lightening that's not even operational yet.
