I saw a thread on here talking about DAG and how it's the blockchain 3.0. I have to take a closer clook at ITC. Crypto lark even mentioned them, so looks like they're gaining some momentum
What about Hashgraph? People are touting that one to be the next big thing. Have you noticed something about all this tech, it is overly hyped and most of it doesn't produce. I would stick with the proven POW blockchain that has shown it can scale over time.
