I just learnt about this project and I haven't had time to go through it to check with algorithm they are running on, but there are two major ways you can check it, number 1 is to read the whitepaper of the project to see what kind of algorithm the coin is being built on because it is always mentioned in the whitepaper so that users can see it, if you have a development background, then you can just go through the code on the github to see what algorithm/consensus is being built on.
Yes, it's now part of the "greenpaper" https://dashgreen.net/Dash_Green_Paper.pdf. That paper was written months after the coin was released. The information in the paper is not on a level were I can see DashG is something unique. It's not even explaining anything in technical detail and therefore it smells like a pyramid scheme where the creators will leave when enough have bought in.
