Blockchains are gaining traction as secure and reliable platforms for data sharing in fields such as banking, supply chain management, food production, energy, the Internet, and medical services. Furthermore, when decentralized, a blockchain can be regarded as an immutable ledger storing data entries. Moreover, this modern technology was designed to disrupt various data-driven industries, including the healthcare industry. While electronic healthcare services have enabled more straightforward and accessible treatment, patient privacy has become vulnerable to external and internal attacks by healthcare personnel. Therefore, we aimed to design a framework to control patient health records that ensures the patient can provide the necessary permissions to those who access his/her health records. This framework will record all activities via blockchain and usage control. Through this framework, we aim to create a user-centric and privacy-aware experience. A literature review and experiments have been performed to select an optimized and placable blockchain operating system. In addition, performance analysis showed that the OS and smart contracts work at an acceptable speed.
