In recent years, information technology has expanded dramatically in many areas as many companies have moved from paper-based methods. However, you will not be able to share information about the medication unless you finish the entire test. Blockchain is essential when it comes to solving key issues regarding data security, integrity and efficiency. All drugs exposed to drug testing must successfully complete several medical studies, each with a large-scale testing of participants. Medical reporting data is often kept in a single database, such as SQL or MongoDB. These traditional methods have a major mistake in this data, and can change in the database even if no one knows when a tester gets sick or throws it away. These disadvantages can be reduced by using blockchain technology, as all nodes connected to the network are notified of data changes. It provides a methodology for optimizing blockchain technology so that it can ultimately surpass traditional systems. We increase transparency and ensure that stakeholders have access to medical research carried out by various organizations using private blockchains. An electronic health file for storing data in a database. You will be connected to the cloud. It stores patient data related to private blockchains, but only authenticated users can view the results of medicall research.
