Yes, NFT Uses HIVE blockchain as a base layer. And same hive account can be used there. https://tribaldex.com/ is a platform build on hive to tokenize things. @nftshowroom uses that.

I believe hive-engine has a similar dpos system as Hive (I haven't checked that properly since they've upgraded), so the costs are pretty minimal as well as electricity and servers running to maintain it.
