**3.2 Blockchain claims in manufacturing control schemes**

Manufacturing Regulate Schemes are used to monitor &switch physical objects that may be found in a variety of different sectors, since organization-critical nuclear facilities to everyday irrigation schemes (ICS).

As demonstrated in **Figure 4**, ICS uses sensors to perceive and gather data, and then transmit that data to the controller, which then uses the actuator to deliver feedback. The following are the essential elements of an ICS environment:


The future transformation of industrial systems will heavily rely on the IIoT. Similar to ICS, the intelligence and connectivity are delivered through sensors and actuators with networking and computation capabilities. It is predicted that billions of data-generating gadgets will already be online and linked to the Internet. Numerous applications, including infrastructure, transportation, and agriculture, will profit from this. In this type of system, transactions involve reading data from various sensors, with time and space tags that indicate where and when the measurement occurred; then, these data are distributed to various network participants. It is important to keep a historical record of these transactions because they are used to influence key decisions. This assumes that the record has not been manipulated and will be tracked when such attempts occur.

A powerful and effective new group of mechanisms for dealings created by corporeal resources is introduced by blockchain. The grouping of BC and the IoT provides us with a multifunctional, truly distributed point-to-point system, and it is possible to interact clearly and reliably with distributed sensors [35]. To implement access control regulations, a BC-based system for safe shared verification is required. To provide both privacy and security, this scheme employs a triangulation with combined quality sign, multi-receiver encoding, and communication verification code [36]. In order to offer a reliable mechanism for the identification and verification of devices, blockchain is utilized to construct virtual zones. The Trust Bubble, a decentralized system made up of several virtual spaces, ensures robust device identification and authentication while safeguarding the accessibility and integrity of data [37–39]. **Table 3** presents ICS design challenges with analysis.

One may automate labor-intensive job processes when all the gadgets in an IoT network are interconnected and equipped with decision-making capacities. Nevertheless, this necessitates that a historical log of these activities and the information that inspired them be kept. According to ongoing scientific study, like the one cited above, the use of BCs in the IoT space will satisfy the demand for cryptographic verifiability, leading to significant improvements across many sectors.

### **3.3 Applications in transportation**

Prospective transportation would depend heavily on autonomous cars, which will also be important for societal advancement. These automobiles have a significant impact on traffic management, and comfort while driving and messaging and road safety. An autonomous, reliable, and decentralized intelligent transportation system, which makes better use of the structure and advantages of traditional intelligent transportation systems (ITS), is especially suitable for crowd sourcing innovation. **Figure 5** presents the ITS national architecture proposed by department of transportation [46]. Physical, data, network, consensus, incentive, and application layers are the seven layers of the conceptual paradigm for ITS. In a heterogeneous intelligent transport system, dispersed key management is also used [47]. In order to cut down on key transfer time, it incorporates dynamic key management and key transfer across heterogeneous networks.

The connected automobiles have in-built sensor capabilities that allow them to monitor their surroundings and provide a thorough 360-degree perspective of what is around. They include things such as cameras, proximity sensors, light and radiofrequency detection sensors, navigation systems, and webcams, to mention a few. In the event of a collision, they have the capacity to synchronize data from several sensors—a process known as sensor fusion—with real-time data to keep the cars and infrastructure components informed. Advanced driver aid technologies including adaptive cruise control, lane departure warning, and collision avoidance systems have increased as result of these features. In order to achieve all these functions, these vehicles are also equipped with communication equipment and protocols for exchanging information between all objects in the vehicle network. Dedicated Short-Range Communication (DSRC) is currently approved ITS 5.9 GHz band protocol for vehicle safety (V2V) applications [48]. Similarly, based on software, the key question to be answered is software updates when new features are added. **Table 4** presents the BC design challenges and future directions in transportation sector.
