Blockchain for Healthcare Management: Enhancing Data Security and Transparency

Abstract

This study examines how using blockchain technology can improve healthcare system control while making data more secure and easier to share between different systems. The study used Proof-of-Authority, Practical Byzantine Fault Tolerance, Federated Learning, and Zero-Knowledge Proofs as advanced algorithms to solve major security problems in medical data handling. The experiment showed the blockchain framework outperformed traditional systems in processing transactions 35% faster while providing more accurate data retrieval by 22%. Our proposed system proved its scalability by handling 500 transactions per second while maintaining 98.5% data integrity. The research found that this framework offered better security results than other systems through stopping unauthorized data access while improving data sharing between users. Studies confirm that blockchain works better when used together with modern computing technologies to improve speed and reduce workload. The findings show that blockchain has potential but also need more research on simplicity of use and resource demand. This work joins existing healthcare studies about blockchain technology by demonstrating its practical approach to secure patient data processing..
