OK, what's one of the most frustrating things about dealing with the U.S. healthcare system? Having to provide the same information about yourself and your medical history over and over and over (and over .  . .) again every time you go into a medical facility, right? 

What if you could simply record all that information on a secure, immutable ledger, and then give someone access to it, and only the information you want them to see, and only at the time they needed it? That's one of the potential promises of blockchain in healthcare, and the UAE is starting to explore it. Keep an eye on this one, we may want to adopt what they learn.
