Different blockchain applications have problems with scalability. It is called the problem of the cryptocurrency and that problem must be tackled. Ethereum and Bitcoin are both working on this, but it is not clear whether this will work out. In that respect, Aeternity is a lot further in the developments. It has a solution and the platform is operational.
Aeternity is based in Liechtenstein, a country that has become more and more favorable for blockchain technology in recent years. Founded by Yanislav Malahov. Malahov has described himself as the Godfather of Ethereum, who was involved in the project from the very beginning. He is now focused on Aeternity.
