The main question I have concerning the applications of Blockchain/DeFi is this: - How to guarantee that you're not dealing with bad actors? Lack of regulation seems to fuel scams and Ponzi schemes, but if we end-up with a highly state-regulated system, I don't see the benefit. Also, what exactly is the pain point? What are we trying to achieve?
