Design and Implementation of Blockchain Collaborated Cloud of Things: A Covid Vaccine Supply Chain Management System

Abstract

Abstract In recent times, there has been a significant focus on Blockchain and Cloud of Things (CoT), which combines blockchain, cloud computing and the Internet of Things (IoT) to offer valuable services in various technical applications. The integration of blockchain and CoT addresses challenges related to network security, data privacy, and decentralization in CoT, while CoT provides scalability and fault tolerance to enhance the effectiveness of blockchain functions. Hence, this paper presents a  conceptual framework design of the BCoT system and outlines the overall structure and principles behind its integration. It provides a high-level view of how blockchain and CoT interact and collaborate to deliver enhanced functionalities andthe PoC architecture of the BCoT enabled Covid Vaccine Supply Chain Management System. It illustrates a practical implementation to validate its functionality.It demonstrates how the different components and layers of the system are interconnected and interact during real-world scenarios.It explores the possibilities and benefits  of the proposed framework, utilizing diverse performance metrics. The results  and test analysis  findings underscore the significance of the proposed work and validate its potential for effectively addressing the challenges of existing system.
