: In recent years, at EHR, we have encountered a number of innovative technologies that integrate mobile devices and cloud computing to facilitate the exchange of medical data between patients and medical institutions. Medical care operates with low cost, high flexibility and safety. In the old system, patient files are stored in a file database, which may lead to high risks, such as theft of the file or the tampering of the patient data in the file by a thief. To solve this problem, we created a decentralized system by implementing EHR based on blockchain technology. Here, we have created an access control system with smart contracts, which is very powerful and can ensure the safe exchange of electronic medical records between patients and healthcare providers. The system proposed in contains cryptocurrency from potential threats (Ethereum stores sensitive health information). The proposed system also led to the certification of doctors, patients and pharmacists. When a patient registers for, a unique block and a hash value are created. As soon as the patient talks about his condition, the doctor can analyze it and prescribe medication. The pharmacist will update and bill later.
