Yeah the potential is there, but execution and connections are key. It will take some work to get accepted and trusted by healthcare providers. New technology comes with risks, and throwing data at a blockchain is definitely risky. It's a big task with unforeseen vulnerabilities. Can one hardfork a healthcare blockchain and provide access to old data, does it get updated to the new chain, or does IT gotta keep a backup of each version?

All I can say is good luck. Blockchain real world implementations like this is what's really needed; not just more websites and payment services. Real world apps.
