Does Blockchain and Internet of Things (BCoT) help in managing customer data?

The internet of things (IoT) is transforming the established sector into a smart sector with "delta-driven decision making. " loT's inherent characteristics, however, provide a variety of difficulties, including decentralization, weak interoperability, privacy concerns, and security flaws. Blockchain technology offers possibilities for overcoming IoT issues. In the realm of the internet of things, the introduction of blockchain has recently sparked a lot of attention. The existing blockchain system, however, has a number of non-trivial issues that prohibit it from serving as a general foundation for extensive IoT services and applications. This study provides a comprehensive analysis of BCoT and explores the lessons learned from this novel paradigm. In particular, the authors first briefly describe the IoT and its difficulties. Then, they provide an introduction to blockchain technology. Next, they focused on describing the IoT and blockchain convergence and outlining the BCoT architecture proposal. They talk about BCoT's industrial uses and the problems of adopting "blockchain for 5G beyond IoT."
