"Hearthy is an EHRP (Electronic Health Record Platform) managed by a protocol that will provide a blockchain-based support for electronic health records. This protocol will insure data safety but not data storage." That statement is from the Hearthy's Medium in twitter. So for those people who still confused about Hearthy's purpose, I hope it helps you.
yeah it's not a data storage, like other think. they just store information of every patient . but it does not mean that it can store big files. it also has a limit.
hearty only wants to break the distance between the hospital and the patient by having a digital application where you can access your file or asking some question regarding on your health issue without getting to a hospital for consultation. correct me if im wrong..
