Totally understandable if this is a trade secret but is there going to be a sort of semi-central yet secure place where the records are updated where physicians and patients log in or is every new test/image sent through the blockchain? Sorry if this is a beginner question. I'm still a total newb when it comes to blockchain. I feel like I kind of have the basics from talks I've heard from Nick Szabo and others but I know I still have a lot to learn.
