Decentralized Healthcare System using Blockchain

Abstract

Abstract—This research paper explores the integration of blockchain technology in healthcare to establish a decentralized system that enhances security, privacy, and patient control over health data. The proposed framework utilizes blockchain's tamper-resistant ledger to create a transparent and secure repository for patient records, ensuring data integrity and confidentiality. Smart contracts enable automated and controlled data sharing, fostering collaboration among healthcare stakeholders. Real-world implementations and case studies illustrate the potential impact of this decentralized healthcare system in revolutionizing data management, research collaboration, and patient outcomes. The findings highlight the significance of blockchain in addressing critical challenges in traditional healthcare systems, presenting a promising solution for a more secure and patient-centric future.
