NANO uses both a DAG and blockchains. The DAG itself is nothing more of a way to say transactions don't have to wait for blocktimes, they just show up as they happen instead of waiting in line for the network.
In NANO every account is a virtual blockchain. This means when you want to send funds, you have to "mine" a low-difficulty block on your own account and simply publish the results of that block to the network. No one does any real mining in NANO, you can think of "mining" your own blocks the same as signing or encrypting messages. Check out https://nanospeed.live for a speed test.
I'm not related to their team or that website and I don't own NANO, but I do follow their news and liked that site.
