I always find it odd to put the two keywords "blockchain" and "DB" together (though I know quite a few similar projects). The essence of blockchain, in my view, is to decentrialize because people don't want or can't have a single authority, whereas DB is centralized. The priority of blockchain is not performance (well, after decentralization, of course you don't have performance), and DB always prioritizes performance. Putting the two together is the most conflicting thing I've seen in the tech world.
