Many blockchain based platform has been used actually, Ethereum is one the most used utilize the platform, we know millions of new token established on the Ethereum platform. There are also Stellar and Waves platform, that I think have almost the same function as Ethereum. And I believe there are tons of other platforms that actually are very useful but not really popular, such as Tron, Obyte, Robotina, WePower, and many other platforms, these platforms only small user now, but it will eventually grow.
Interesting, I have not heard of many of those. Wepower is a good example of what I am looking for. A coin that has utility built in but does not have to do with other coins as a utility use case. Unfortunately, I dont believe wepower is anywhere near easy to use. I also don't believe it has over 100000 transacted (in their electricity market) monthly. That's a small number and there should be at least one project that has that.
