Decentralized medical records, built on blockchain technology, allow patients to control their health data while ensuring secure, immutable storage. This system can eliminate centralized databases prone to breaches and allow authorized healthcare providers to access real-time records. However, challenges include integrating with existing healthcare infrastructure, ensuring patient privacy, and gaining regulatory approval. Additionally, ensuring interoperability between different blockchain platforms remains critical. If these challenges are addressed, decentralized medical records could empower patients, improve healthcare efficiency, and reduce administrative overhead.
