What Advantages Does Blockchain Technology Bring to the IoT?

The use of cloud networks has enabled the interconnectivity of internet-enabled devices, paving the way for smart cities of the future. However, this increased reliance on traditional infrastructure leaves the door open to potential security breaches that could lead to the disruption of private information. Fortunately, blockchain technology has the potential to provide a secure solution to this issue.

This essay aims to provide the reader with a comprehensive understanding of the technology behind blockchain and its relationship to the Internet of Things (IoT). It will explore the various uses and applications of blockchain and how they are applicable to the IoT. Furthermore, this essay will also consider any potential challenges or implications of these technologies in the future.

A brief introduction to distributed ledger technology and the Internet of Things

  • A blockchain is a type of distributed digital ledger technology that records information in a way that makes it impossible to modify or alter. It works by replicating and distributing transactions across a wide network of nodes, where they are processed and stored securely. This ensures that the data is immutable, making it a reliable and secure storage solution for sensitive information.
  • A blockchain is a shared digital ledger of all the transactions that have ever taken place across the whole blockchain network of computers.
  • In contrast to traditional computing systems, the Internet of Things (IoT) is a network of interconnected and intercommunicating devices, physical and digital machines, and objects, animals, and people, which are able to exchange information and share data by making use of their individual unique identifiers (UIDs) and the Internet.

A blockchain solution for IoT security

At present, the number of internet-enabled, intelligent devices has surpassed one billion. We are standing on the brink of a revolution that will have a major impact on the electronics market and many other industries, with an estimated hundreds of billions more devices to be manufactured in the future.

The utilisation of Internet of Things (IoT) technology enables businesses to gather data, assess it for strategic insights, and make decisions based on those observations. Consequently, this data can be relied upon with a high level of trust and assurance.

The question of appropriateness arises when considering the use of data for decision-making and business operations that cannot be independently validated. With the multitude of potential applications for the Internet of Things, a common challenge is the absence of assuredness in the data being used.

In the Internet of Things (IoT), blockchain technology has the potential to facilitate the secure storage and transmission of data. The core concept is to provide each device with a unique identifier at the time of manufacture, which can then be verified and authenticated through blockchain technology at any stage of its lifecycle. This would enable the creation of a tamper-proof system of record-keeping, ensuring that only legitimate data is recorded and shared.

The utilisation of blockchain technology, in combination with device identification standards and reputation systems, holds great promise for Internet of Things (IoT) systems. Device identifier protocols allow each device to have its own blockchain public key and to communicate secure challenge and response messages with one another. This ensures that the device can maintain its individual identity. A blockchain can also be used to keep a record of a device’s reputation or history when it has a unique identifier.

The community in Brooklyn, New York is leveraging blockchain technology in an effort to improve their ability to monitor solar energy production and facilitate the acquisition of additional renewable energy credits. Through the use of this technology, the device will be able to build character and credibility over time as its transactions are tracked and recorded. Additionally, it provides the opportunity for people to combine resources in order to make larger purchases, distribute the maintenance costs, and ensure that the device is accurately reflecting their solar power output.

Dapps that use blockchain technology to execute smart contracts

Smart contracts are digital representations of a set of business logic that are programmed to execute when certain conditions within a blockchain network are met. When a transaction is proposed, these contracts are triggered and automatically execute the protocols set forth by the underlying blockchain network. This automation of transactions, interactions, coordination, and permission can be highly beneficial in the context of Internet of Things (IoT) networks, as it can streamline the process of data sharing and security management.

It is evident that smart homes are increasingly becoming outdated, and the potential for interconnectivity being integrated into nearly every facet of modern life is rapidly growing. When an issue arises with the Internet of Things, these devices may even take proactive steps to address the problem, such as ordering a new part. However, it is necessary to impose regulations on the actions of these gadgets. Smart contracts are an excellent way to manage this.

As the Internet of Things (IoT) evolves and is adopted more widely, the capacity to supervise and manage connected devices and the activities they carry out from a distance is increasingly necessary. Combining these abilities with IoT is a logical choice to be made with the assistance of smart contracts and blockchain technology.

IoT blockchain’s many advantages

Even though blockchain technology and the Internet of Things (IoT) are both powerful and effective on their own, organisations may find that unifying them together can yield even greater benefits. This innovative combination is referred to as BCoT, or the “Blockchain of Things.” By combining the two technologies, organisations can create an even more secure, efficient, and powerful system for all their needs.

  1. Rapidly evolving data

    Aftrex Market Research has highlighted one of its major advantages as being the continual updating of data. However, Michael Leone, a Senior Analyst at Enterprise Strategy Group (ESG), has expressed the opinion that this use case is limited by the current blockchain implementation’s low transaction throughput.

    According to Leone, a permission-based blockchain is essential for dealing with the high volume of data, number of IoT devices, and rapid communication speed between two parties that is associated with the Internet of Things. Consequently, a blockchain with the capability to reduce the time needed to finish transactions through the implementation of reliable nodes is deemed indispensable, as is one that is able to manage the speed at which IoT data is exchanged.
  2. More protection for everyone

    Blockchain technology is renowned for its capability to authenticate data and guarantee its source is trusted. This is particularly useful with the rapid increase in the number of internet of things (IoT) devices that are now in circulation.

    The implementation of blockchain and Internet of Things (IoT) technologies may provide enhanced security and privacy for communications. By leveraging a reliable ledger that records who has access to the network and is executing transactions, organisations can benefit from a strengthened security posture. Additionally, improved privacy agreements that are enabled by blockchain and IoT are likely to increase trust between parties, as well as ensure that the data is handled in accordance with any applicable regulations.

    Businesses that incorporate blockchain technology with the Internet of Things (IoT) in order to further enhance their security often employ additional safeguards, such as device authentication. Despite these additional measures, security concerns regarding blockchain and IoT are just the beginning of a much larger issue.
  3. Supply chain that works efficiently

    In recent years, numerous organisations have implemented strategies to enhance the performance of their supply chain operations. Unfortunately, these efforts are often hindered by a host of economic and international issues. Fortunately, the utilisation of blockchain and IoT technology has the potential to reduce inefficiencies, accelerate transactions, and reduce associated costs in the supply chain, thereby improving its overall efficiency.
  4. Cost savings

    One of the most frequently discussed benefits for businesses is the potential to reduce operational costs. By allowing data to be sent directly between entities without relying on a centralised entity for control, organisations may be able to realise cost savings and reduce the possibility of their operations running into difficulty.
  5. Explicit bookkeeping

    One of the first areas of a corporation to gain from the more openness that blockchain and IoT provide would be accounting.

    The creation of a linear chronology of who is performing transactions with money or data, with a time-stamp, is highly advantageous, as Leone explains. From an auditing perspective, a translation layer is required for the purposes of verification, however the immutability of the transaction chain is highly beneficial for accounting purposes.

    It is evident that the Internet of Things (IoT) stands to benefit tremendously from the application of blockchain technology. This is due to the fact that IoT has been unable to provide an adequate level of security for its vast array of connected devices and networks. Blockchain technology, on the other hand, is renowned for its superior security capabilities, making it a natural fit for IoT. The potential of combining these two technologies is nothing short of remarkable.
