Abstract:
Blockchain technology presents a promising solution for healthcare, addressing key challenges
like data breaches, patient control, and interoperability. This paper analyzes blockchain applications
in three areas: electronic health records, pharmaceutical supply chain traceability, and clinical trials.
The authors explore security concerns, regulatory compliance, and smart contract vulnerabilities,
proposing solutions like advanced cryptography and improved consensus mechanisms. Real-world
examples, such as Medicalchain and Chronicled’s MediLedger, demonstrate enhanced transparency
and security. However, adoption faces barriers like scalability, computational costs, and regulatory
complexities. The study also highlights ethical issues around data ownership and suggests future
research into improving interoperability and integrating technologies like artificial intelligence and
internet of medical things for better healthcare outcomes.
