The Blockchain and IoT Equation

Before starting with a reflection on different use cases of blockchain in IoT, it is important to understand ‘How blockchain can be used in IoT?’ effectively. Blockchain has already been through a radical evolution process alongside reaching the peak of hype followed by a trough of disillusionment. Now, it is slowly coming back on track again towards an upward trend. Many recent events and their related influence on the connected economy have led to new standards for digitalizing transactions. 

Blockchain gives the perfect technology foundation for enabling digital transactions among organizations. Blockchain helps in the secure recording of transactions along with the assurance of immutability throughout different computers associated with each other in a peer-to-peer network. The emphasis on blockchain IoT projects largely draws strength from such traits in blockchain technology. In order to get a better understanding of how blockchain can help IoT projects, it is important to delineate its working in the context of IoT ecosystems.

The Working of Blockchain Technology for IoT Use Cases

The uses of blockchain IoT depend prominently on the three basic traits of blockchain technology in the form of a data structure. The three basic properties of blockchain technology that could benefit IoT use cases include,

  1. Distribution
  2. Decentralization 
  3. Immutability

A simple explanation of using these three blockchain properties for improving IoT use cases could verify the feasibility of blockchain IoT projects. Let us assume the example of surveillance cameras as IoT devices to understand how these three traits could benefit IoT. Now, if a burglar wants to compromise a surveillance camera and prevent the crime from being recorded, they can attack the server that runs the database storing the videos.

      1. Distribution

With blockchain, the data does not stay in a single place and is distributed throughout different computers on the network. As a result, it is quite difficult to hack the surveillance system with multiple target devices. In addition, the redundancy in storage offered by blockchain improves security and data access. How? Users in the IoT ecosystems could easily submit and retrieve their desired data from various devices effortlessly. 

      2. Immutability

The blockchain IoT use cases are also evident in examples where the burglar might claim that video evidence recorded by surveillance cameras is forged. In such cases, the immutability of blockchain comes to mind. It implies the detection of any changes in the stored data. As a result, the court could verify the burglar’s claim by searching for attempts to modify the data. 

      3. Decentralization

Although immutability and distribution safeguard the integrity of IoT device data on blockchain networks, decentralization could be a prominent setback. Decentralization could open up sensitive data of users to third parties. However, it is possible to find a way around such setbacks. The IoT blockchain use cases could involve the storage of access logs and permissions as a preferred solution. 

With the distribution and decentralization traits of blockchain, big data storage can be exceptionally expensive. So, the favorable alternative, in this case, would be the storage of data in a central repository. At the same time, the logs of data access would go on a blockchain network. As a result, users can get an immutable data structure with the flexibility of identifying the identity of individuals accessing data and the time of the event.
