There are plenty of potential developments which can make Ethereum a more versatile and robust cryptocurrency project. Scaling remains its main problem, albeit that can be said about most currencies and digital assets on the market. Raiden, one of the heavily touted solutions has now made its way to the Ethereum mainnet. At least, the Red Eyes release has done so.
It has been a while since people actively discussed the Raiden Network. Once touted as a major breakthrough for Ethereum in terms of both development and scaling, it has become far less of a hot topic than people would assume. Originally introduced several years ago, it has taken some time to get this project even close to release ready. Not abnormal in this industry by any means, though.
