Quite honestly, the various uses are limited only by our imagination. This is like asking the question "what are the various uses of the internet?" back in 1995. It's a wonderful question!

We're so early on in blockchain we haven't thought up or realized a fraction of how this technology will be used.

Currency is a great first application, obviously. But blockchain is a keeper and transactor of information. So think about how much information is exchanged for various business or societal activities? And then think about how valuable it would be to have a more secure and error free method to conduct those transactions of information? That's the best benefit of blockchain technology.

We have an exciting future ahead of us with this one!
