quite an unusual way of mining. I did not think that I would sometime see the possibility of combining both algorithms, apparently this day has come))
Well, I would not say that this is a very new way, many projects have already implemented it, and some will soon apply it. For example, the crypto currency and the platform ETH. They will have a transition from Proof of Work to Proof of Steak. And for a while there will be one and the second algorithm to work)
I also heard about this transition. It is high time, mining with the help of electricity is not environmentally friendly and not safe. In addition, it is already quite expensive!
