Abstract
One of the major problems facing the healthcare system in the kingdom of Saudi Arabia is the difficulty in sharing medical data between hospitals. Therefore, the patient may suffer when he/she moves from one hospital to another which leads to waste of time, money, and resources. Another problem facing the healthcare system is data loss which could be caused by attackers, corruption, or viruses. Accordingly, this project aims to solve these problems using blockchain technology and creates a peer-to-peer network for healthcare systems in the kingdom of Saudi Arabia to store uniform electronic health records. Moreover, this project allows sharing and exchanging electronic health records between hospitals, provides high security and synchronization, and allows access to health information at any time in a faster and easier way.
