The idea of “Industry 4.0” is revolutionary and has far-reaching effects on many different industries around the globe. Industry 4.0 uses new-generation, state-of-the-art engineering technologies and methodical adaptability to drive development as a technological accelerator. The Internet of Things (IoT), blockchain, Artificial Intelligence (AI), Augmented Reality (AR), printing in three dimensions, cloud computing and big data analytics are some of the key innovations that collaborate to realize the Industry 4.0 vision. A Cyber-Physical System (CPS) allows the exchange of information between physical things and a linked network of technologies and objects by combining computational and storage features with the physical objects. A novel distributed computing paradigm called blockchain offers a viable remedy for contemporary CPS applications. Strong options for CPS applications are offered by the natural combination of distributed memory and consensus techniques with cutting-edge security mechanisms. Blockchains in CPSs/IoT provide safe and preserved data for many industrial purposes and accomplish flexibility, procedure, and operational security, for instance, in activities related to production, logistics, medical care, and power.
