The integration of blockchain with the Internet of Medical Things (IoMT) has emerged as a transformative approach in healthcare, offering enhanced security, privacy, and transparency in managing sensitive patient data. This paper explores the potential of blockchain technology in addressing critical challenges within IoMT-based healthcare systems, including data integrity, interoperability, and decentralization. By reviewing architectural frameworks, real-world applications, and scalability solutions, the study outlines how cryptographic methods, smart contracts, and decentralized storage mechanisms can optimize healthcare services. This highlights ongoing challenges such as standardization, storage demands, and performance trade-offs while proposing advanced cryptographic and architectural solutions. The findings provide a comprehensive roadmap for developing secure and scalable blockchain-integrated IoMT systems that can support real-time, privacy-preserving medical data management.
