I am wanting to create a digital community that uses its own virtual currency that can be purchased like from an exchnage, though I've personally never done this before. So we would control some currency distribution and be able to exchange it for positive efforts within the app, but they could go to an exchnage and cash it out or use for purchases within the app. I have a colleague on this project that has studied digital currencies pretty extensively and he is talking about sidechains like using Cardano as an option.
My question: is this realistic using FlutterFlow and any suggestions or tool sets I should be exploring to do so?
