CareChain implements EMR storage through a decentralized system that uses IPFS with Ethereum blockchain infrastructure. CareChain provides healthcare institutions with an alternative solution by addressing data risks inherent in traditional centralized management systems without patient control. Off-chain storage with IPFS works efficiently and at scale, just as smart contracts make it possible to control medical information access. Patients can manage access to trusted healthcare professionals by giving them control over their medical records through the system. Quick and accurate medical information exchange through this system helps healthcare practitioners improve diagnosis and therapy. By being decentralized, the platform delivers better security along with stronger reliability by breaking its dependence on one central authority. The CareChain platform provides safe medical information exchange between different healthcare systems while simultaneously ensuring reliable data privacy and accuracy. The system architecture designed for patients enables secure handling and sharing of medical data through a dependable structure that grows with demand, fitting digital healthcare trends.
