The healthcare industry is one area where blockchain technology is being used to ensure security and reliability. Blockchain is like a big list where each new transaction is added to the end of the list, and each transaction is connected to the one before it. This creates a secure and unchangeable record of all transactions. To make sure everyone agrees on the new transactions being added, blockchain uses methods that involve everyone checking each other’s work. Patient information is very sensitive, so it is important to keep it safe. In the past, each hospital stored patient information separately, which made sharing information very difficult and risky. By using blockchain, it can share information more easily without worrying about being changed or stolen. The goal of this research is to combine blockchain and healthcare to make sharing information more secure and efficient.
