Why not using an already existing platform, add your wanted feature and that is it?
Proof?
(any decentralized platform + new feature <-> Ethereum + new feature)
Go over to the Ethereum forums and ask the developers over there, they can vouch for that better than I can as I am not a developer and have not tried developing anything using Ethereum. I am just someone that took 2 years of programming classes 10 years ago, and haven't done much coding since as it was rather boring and tedious for me. Yet, I have enough general knowledge of most basic computer science areas, and understand how Ethereum can be a great thing for decentralized applications.
I'm not sure why you can't come to that conclusion yourself, but I would venture to say you have an agenda. I have read that you are a Nxt developer... Tell me how well YOUR decentralized applications are coming along? I heard a lot of them are not coming along so quickly. Maybe you guys should look into using Ethereum?
