This concept is very interesting. Is there an existing framework that implements this? It would seem there would need to be some baseline tools for development on such a system. I feel like the tools available for this purpose would need to be more powerful than existing IDE systems in order for it to be adopted on a wide scale. Is it possible to design such a system without a blockchain?
