**1. Introduction**

Cyber-physical systems (CPSs) is a sort of architecture that combines sensing and communication technology to give the society a number of advantages. To put it another way, a computerized process system (CYPS) is an engineering structure whose physical system or procedure is made up of cybernetic elements such as computing hardware and a communication network [1]. All the mechanisms of CPS are same tightly combined with respectively other, by which we can understand that the functionality of single module depends on the additional factor. The CPSs have a sequential development in current years in the fields of energy, smart homes, smart vehicles, health, transportation, and industrial Internet of Things (IIoT). The main expanses of investigate to be considered for scheming such schemes to be keen, effective and flexible, remain constancy, dependability, robustness, safety and confidentiality.

Rapid development of technologies also made such schemes for thoughtful and profound risks. If such dangers remain not attained, then we would misplace all the assistances that the CPS provides. Blockchain establishes trust among the nodes to generate new basics for most dispersed arrangements. The important technology to allow decentralization that plays a significant part in CPS field is blockchain.

Blockchain (BC) is a protected numerical ledger of dealings that not only maintains records of the economic world but similarly in additional areas that maintain historical sign of the dealings that has charge. This is the core skill of Bitcoin. Financial establishments, for a long time, consume negotiated around the need aimed at the circulated decision-making procedure, but never took it on to the next step, till the beginning of crypto-currencies fueled through the BC skill [2].

Firstly, the blockchain skill was mainly used for defending the economic transactions, smart contracts, storage space systems, and notary. However, the assistances were not sticked to particular needs but there were also other requests such as supply chain, health care, and transportation. The manufacturing comprehended that blockchain can expand the effectiveness. This made an active part of effort, where researchers and professors are now observing at other submissions where blockchain can be exploited.
