The healthcare industry has undergone a significant transformation with the emergence of Internet of Things (IoT) technology. Various computing paradigms, including cloud computing, fog computing, and edge computing, have emerged to address challenges in processing, storing, and analyzing data in modern systems. This paper proposes an advanced architecture for healthcare systems based on our research team's previous work. Our research focuses on developing a smart healthcare system to assist diabetes patients in managing their illness. Our novel architecture builds on the previous one, which included blockchain with IoT, by incorporating a blockchain-based edge layer to address scalability and security challenges that were previously encountered.
