Blockchain in Healthcare

> While blockchain technology would not have prevented such attacks, it could, in some instances, have prevented the hackers from being able to access much of the confidential data.

> Since the access and transfer of data can be made more secure by blockchain, it facilitates a more trusting environment where doctors, patients, and third parties can regularly transfer data to one another.

This is some hand-wavy bullshit. How does Blockchain tech prevent access to confidential information? How can it be made more secure?

> Blockchain-based electronic health records would allow records to be easily sent from one location to another making them, in effect, the first ever anywhere anytime electronic medical record. To potential of these kinds of records to transform patient care is enormous.

Sure, except you need to send the entire blockchain - or you can send excerpts, in which case there's no need for a blockchain.

I'm tired of reading and pasting excerpts. This reads like a high school junior trying their best to justify picking an essay topic to a teacher. I'd give this a generous D-.
