Abstract

This paper offers a broad overview of blockchain's utility in the healthcare sector, moving beyond basic data management to explore complex applications such as clinical trials, medical record portability, and drug verification. The authors utilize a multidimensional approach to evaluate how blockchain's decentralized structure offers inherent advantages over legacy centralized databases, particularly in preventing data tampering and ensuring transactional trust. Through a critical analysis of current limitations—such as latency, energy consumption, and high costs—the authors provide a roadmap for future development. They emphasize the integration of blockchain with other emerging technologies like the Internet of Medical Things (IoMT) and Artificial Intelligence (AI). The contribution is significant for its holistic perspective, balancing technological optimism with practical engineering constraints, and providing a foundation for stakeholders to evaluate where blockchain offers genuine value over traditional database technologies.

Key Findings

  • 1Blockchain improves trust in healthcare by mitigating the risk of unauthorized data modifications.
  • 2Integration with IoT and AI is identified as a critical catalyst for future blockchain adoption.
  • 3High latency and power consumption are significant barriers for real-time medical data transmission.
  • 4The study recommends a focus on standardization to facilitate cross-entity medical data exchange.
