**3. CPS related to blockchain**

Through the increasing popularity of processers in the earlier few eras, accounts consume changed after primarily paper credentials to digital versions shaped and then maintained on computers.

This is single of the numerous cyber requests, the ones permitted through processors. Even though these documents are made and kept electronically, information must still be entered manually. It can be claimed that people are still the major source of information gathering in these applications since money transfers, health records, and coverage records are only a few of the numerous instances in this category.

The sensors increasingly taking the place of people as the main data collecting source in many organizations, thanks to the rise of IoT and the growth of sensing technologies over the last several years. These systems, also known as CPS, bring together physical processes, software, and information to create a cohesive system with design, analysis, and abstraction capabilities. A number of disciplines are involved in the study, which has as its fundamental elements used for dynamic analysis.

BC financial transactions have been extensively studied and recorded. All of these technological advancements have made it possible to transfer money directly to approve individuals without using centralized authority. The use of smart contracts on the BC reduces the likelihood of delays, suppression, or other outside influences. This is unbreakable, ensures total financial stability, and maintains track of the conditions of the contract. It is also easier to track and manage online identity when utilizing blockchain. Blockchain is employed as a low-cost notary system, as detailed in Ref. [11], preventing various frauds by producing distinctive certificates that would be simple to validate. **Table 1** represents BC technology applications.

### **3.1 Health and medical level BC applications**

BC is currently existence cast-off in community strength and health investigates grounded on patient data and application management. Assessment criteria depending on viability, planned capabilities, and acquiescence may be rummage-sale to evaluate BC-based decentralized systems in the healthcare sector [12]. This is the fundamental advantage of blockchain, which is crucial for health data since it makes it difficult to modify or erase a record while leaving a data trace of the effort. Blockchain is being used by several nations to safeguard clinical trial and health archives by associating access to the information with authorization locations. BC

also provides safety overslide, allowing the use of barcodes to scan medicines and helping them enter secure digital blocks when ownership changes, thereby reducing the risk of counterfeiting. There is supply chain access to real-time records. Blockchain can be used for a variety of applications, specifically information sharing, admittance regulator, medical analysis, management, and supply restraint management [13].
