Blockchain technology is being used in the healthcare industry to create fair agreements. In the medical industry, a blockchain network is utilized to protect patient data that is acquired from pharmacies, doctors' offices, hospitals, and diagnostic facilities. Blockchain-based applications have the capability to detect and alert users to absurd or potentially dangerous mistakes in the medical domain. Blockchain technology can solve several issues with data management, interoperability, security, and transparency, which could result in major advancements in the healthcare sector. Blockchain technology could improve healthcare systems' efficiency, security, and transparency to overcome issues with conventional health data management systems. This could ultimately result in better patient outcomes. It's crucial to remember that interoperability, privacy, and regulatory concerns must all be carefully considered before implementing blockchain in the healthcare industry. To curb drug fraud and provide patients greater control over their information, the authors of this paper examine current trends and highlight the potential benefits of blockchain technology in the healthcare sector.
