Thanks for the idea. Basically that's why I'm considering DApp - new stuff. Also new language - Solidity. On top of that new paradigm I'd say. Refreshing. Yet something practical - I mean I could Imagine building a mvp. On the other hand building a gRPC which you suggested is more like system programming with target audience other developers and their software - low level stuff. Guess I'm more on the other side. Did you switch at some point after doing same stuff for years?
