I more think that we'll see things shift to a hybrid future of POW and POS and variations of each on the same chains that seems to be the most secure version of locking down networks to be as secure as possible
So you are talking about something similar to what's planned for Ethereum with the Casper protocol? But in this case it wouldn't be necessary to mine ETH anymore, right? In case more projects will go this way, it's good that Neuroneum doesn't focus solely on crypto mining.
