Cloud of Things and Blockchain Integration: Architecture, Applications, and Challenges

Abstract

The use of Blockchain technology is rapidly expanding. Blockchain’s autonomous, transparent, and secure properties will assist the next generation of varied industrial applications. Cloud technology and indeed the Iot Cloud from the Internet - Of - things Corporation are two examples (IoT). Here, blockchain offers novel approaches to Cloud of Things' difficulties with decentralization, privacy regulations, including traffic analysis, while Cloud of Things improves to the efficiency of blockchain operations with its flexibility and scalability. Since the BCoT model is an innovative paradigm that brings together digital currency and the Internet of Things, it has the potential to facilitate a broad variety of use cases. The purpose of this article is to introduce the BCoT from the several perspectives, including its background, justification, and integrated design, by presenting a state-ofthe-art assessment of BCoT integration. Further, we provide an in-depth evaluation of BCoT applications, discussing their potential in 5G technology and beyond, in addition to their specific use-case sectors. In order to help researchers and app creators locate and stay up with the most latest technologies in this rapidly growing market, we provide an in-depth review of the new BCoT tools and services.
