The entirety of Crystallographic currency has been based on a single layer network. I think making a two tier network has opened tons of doors. That and now, using quorums to split the tasks has simply empowered an already super healthy Masternode Network possibly eventually over 1000 fold (currently, what? 660 fold?) over "traditional" ways.
So, IMO, it's not magic, it's simply harnessing ideas from other walks of technology for use in cryptographic currencies. Bitcoin hasn't done anything, really, NOTHING since I got here in December 2013. They may have cleaned up the code, made the wallet work smoother, but have introduced nothing structurally new that a person like me can see. I know you coders can appreciate whatever they did do. And I'll admit, my wallet did download in a couple of days recently rather than 3 weeks, like it took the first time I tried, but frankly that's boring.
The technology that the Dash team are introducing isn't mumbo jumbo, it isn't untested. Sure it may be untested in this type of use, but it has been tested in other uses and reviewed and shown to work so why not in this instance?
Anyway, Just saying, no magic here, only thinking outside the box and doing research. In other words, hard work with clear goals and an abundance of intelligence and wisdom.
