A family of wearable or implanted medical devices known as the Internet of Medical Things (IoMT) gathers information about a patient's health. These gadgets easily detect a range of health factors, including body temperature, heart rate, blood pressure, and oxygen saturation. In reality, one of the most important roles in healthcare cooperation is inter-stakeholder medical data sharing. Due to the possibility of data leakage or manipulation during operation, sharing medical records among participants is extremely difficult. Electronic medical record solutions built on blockchain technology hold the solution to addressing these issues. Medical data are sensitive, large-volume, and need a high level of security. These files, which are known as electronic health records (EHRs), are digital health records that are electronically maintained. EHRs are commonly shared among healthcare stakeholders and are vulnerable to security flaws, privacy violations, and abuse of data. The emerging field of blockchain technology allows nodes in a network or networks to communicate with one another in a distributed and decentralized manner without the need for a central authority. Researchers are concentrating on applying blockchain approaches to improve security in healthcare applications. Patients can benefit greatly from blockchain technology's decentralized structure when combined with the IoMT devices in terms of convenience and privacy. In general terms, the usage of blockchain enables relatively convenient and decentralized data and information communication between hospitals and patients. When the EHR is transferred to the blockchain via a secure smart contract method, the system may easily reduce fraudulent data and information mutation. Blockchain security policies facilitate the development of trust among stakeholders.
