Design and Implementation of a Blockchain-Integrated Cloud of Things for COVID-19 Vaccine Supply Chain Management system

Abstract

In recent times, there has been a considerable emphasis on the Blockchain and Cloud of Things (CoT) paradigm, which integrates blockchain technology, cloud computing, and the Internet of Things (IoT) to provide valuable services across various technical domains. The combination of blockchain and CoT addresses issues related to network security, data privacy, and decentralization within CoT, while CoT offers scalability and fault tolerance that enhance the functionality of blockchain. This paper introduces a conceptual framework for a BCoT system, detailing its overall structure and the principles behind their integration. It offers a high-level perspective on how blockchain and CoT collaborate to deliver improved functionalities and presents the Proof of Concept (PoC) architecture of a BCoT-enabled COVID-19 Vaccine Supply Chain Management System. The paper illustrates a practical implementation to verify its functionality, demonstrating the interaction and interconnection of the system's various components and layers in real-world scenarios. It explores the potential and advantages of the proposed framework using a range of performance metrics. The results and test analysis underscore the importance of the proposed work and confirm its potential in effectively addressing the challenges present in existing systems.
