Abstract The dynamic changes which take place globally coincide with the trends and changes happening in technology as well. The power of technology propels several sectors of the world, majorly industrialization, which has been the driving force of modernization. It is imperative to recognize the value of data and data transmission in the age of computers. Hence, the IoT avails a proper technological system with different software and platforms for data transmission between different devices and computer systems. Nonetheless, Blockchain technology joins data privacy because of its impenetrable characteristics changing the face of computer systems. In this paper, we'll analyze the results of combining Blockchain and IoT technologies.

The increased network agility and comprehensive Artificial Intelligence systems widen the capacity of any industry to automate its production process effectively. The physical entities embedded in a system to connect different domains for data transmission play a vital role in achieving communication (Borgini, 2021). For example, the increased reliability of cloud platforms has ensured that businesses and consumers have clear access to the infrastructure they require to propagate themselves. The emergence of these cohesive technological platforms widens the functionality of Internet of Things (IoT). Nonetheless, IoT has ensured creation of market places for different services concurrently functioning with Blockchain technology to ensure data transmission is safe and secure. Regardless, data management is solidified in IoT device by galvanizing the system with Blockchain technology to protect sensitive data from reaching the wrong hands. IoT enables various devices to transmit data to private Blockchain networks which develops transaction records via the Internet.

modification or hacking. Additionally, a Blockchain offers a digital platform for recording transactions distributed across computer systems, functioning as a ledger. Therefore, a Blockchain is a ledger that decentralizes confidential information to selected participants in a computer system (Gross, 2020). The availability of consensus algorithms ensures that instructions in the Blockchain system are followed.


    The IoT yields tremendous advantages for different entities using them on a global scale. The fundamental advantage is easy data monitoring because the IoT provides comprehensive data that improves resource utilization (Borgini, 2021). Additionally, minimal human effort is required as the different devices can interact with each other. In this sense, several multinational companies handling global markets have incorporated automation in their production. Far from that, the IoT enhances data collection, storage, and retrieval, concurrently improving security.


    Despite the ability to quickly and efficiently, the IoT heavily relies on the Internet as the driving force behind its functionality. Lack of Internet hinders the process of collecting and transmitting data between computer systems. Nonetheless, hackers may also have access to vital information and data (Mohanta, 2020). The sophistication of the systems creates a higher chance of failure or lagging because of the system's complexity (Reyna, 2018). IoT additionally offers weak data protection in reference to Blockchain technology. Absence of blocks interconnected to facilitate transaction exposes data to factors such as cyber- attacks which have devastating effects (Mohanta, 2020).

    1. ABOUT IOT

      The IoT refers to a system of interconnected objects cohesively operating together to collect, transmit, and decipher data over a wireless network (Mohanta, 2020). Moreover, new technologies require connectivity channels to exchange data if innovation evolves because the IoT makes connections safer (Gross, 2020). Not only can businesses be able to generate data, but the energy consumption is also more efficient with the IoT.


A Blockchain incorporates a complex system of recording essential information to shell it from infiltration through


    The value of Blockchain technology stems from the capacity to transmit data fast and securely from one system to another (Devi, 2019). The sequence safeguards data and facilitates transactions because of the unique characteristics in the computer systems. Moreover, Blockchain technologies cultivate trust in different entities hence increased willingness to engage in business (Battrick, 2020). Blockchain ensures data is transmitted within an ecosystem of entities where none is exclusively in charge hence decentralization for different companies and producers. The ability of a

    Blockchain to develop an unalterable record of transactions ensures that the data is protected, making it nearly impossible to infringe or hack (Battrick, 2020). Furthermore, Blockchain technology creates unmatched efficiencies in processing transactions streamlining organizations' operations.


    1. Applications of IoT

      IoT a technical intersection, which provides authorization to numerous digital and mechanical computing devices. This unique technology reaps tremendous benefits in telemedicine and healthcare, smart grids, self-driven cars, wearables, online shopping, automotive, smart agriculture, smart supply chain, home-monitoring, transportation, and smart-grid (Power or Intelligent grids). IoT reforms in everyday things getting connected for smarter structure flow.

    2. Applications of Blockchain

    Cryptocurrency and bitcoin are only a small part of what blockchain can do. With its ability to increase openness and fairness while simultaneously saving organizations time and money, technology is having an impact across a wide range of industries, in providing better data security and privacy. The significance of this technology involves in secure sharing of medical data, cross-border payments, secure trading, digital voting, digital IDs and social-management. Additionally, the interlinked computer systems ensure data security and privacy through Blockchain technology can be manipulated into a standard security protocol (Devi, 2019).


    IoT has several drawbacks, such as weak password protection because the hard-coded credentials threaten IT systems (Mohanta, 2020). Moreover, the lack of regular patching and updating makes them vulnerable to hackers (Pajooh, 2021). The most frequent concern for the Internet is insufficient data protection because compromised devices can acquire confidential information. The lack of skills on IoT clouds several operations because a successful IoT requires experience and skills, which most companies lack.

  4. HOW TO OVERCOME THESE CHALLENGES Companies should enforce flexible security settings with

    options such as password expiration which would push users to modify their passwords frequently. Two-factor and multi- factor authentication can be alternative security protocols Pajooh, 2021). Additionally, entities can issue a security update from IoT device to Blockchain authentication to secure access to devices and information it generates. Moreover, Blockchain facilitates frequent data encryption, and decryption ensures data privacy and confidentiality, minimizing the risk of data theft because hackers would leave an invalid, traceable signature.


    Blockchain reliability in the IoT capacitates a network to efficiently record assets. Hence, IoT ensures that appliances and devices linked to the Internet share information to Blockchain networks, enabling access to IoT data without central administration and control (Reyna, 2018). Additionally, what stands out in Blockchain technology is the capacity to protect data distributed across a network of people, making management easy compared to the IoT.


In conclusion, Blockchain technology edges over the IoT because of its inherent security qualities. The cohesion between cryptography, decentralization ensures trust in the transaction. Moreover, data security and privacy are efficiently achieved because of the structured blocks which streamline in a cryptographic sequence (Devi, 2019). This ensures that it is nearly protected and impossible to interfere with. As far as businesses are involved, Blockchain protects crucial data to break it down into smaller portions for software storage.


Any task's accomplishment is dependent on the efforts of the individual, yet it cannot be accomplished without the assistance of others. As a result, we'd want to express our gratitude to S.J.C INSTITUTE OF TECHNOLOGY for allowing us to partake in this paper.
