ABSTRACT
Cyber-physical systems (CPSs) are systems that combine physical components with built-in computational power and data storage. CPSs can be connected to one another in networks, where they can communicate and exchange data and information with other systems and objects. In a cyber-physical system, computational components work together in communication with sensors. The data that each device collects is kept in the cloud for later processing after being identified, authorized, and connected by cloud servers. Although this model has been used for decades to connect computing devices, it will not be able to meet the expanding requirements of the large-scale CPS ecosystems of the future, which will have billions of connected devices. Furthermore, the design of the current architecture has produced isolated data, where individuals have even less access to their data. Users are compelled to believe the promises of security and availability made by the cloud and application suppliers. Blockchain technology is a decentralized digital record that houses user-committed transactions and is an innovative breakthrough in the field of information and communications technology. This blockchain technology shows a good potential to address the problems due to cloud storage and can be used to provide positive solutions for CPSs.
