With these disruptive statistics, let’s dive in to know more about the attention-seeking combination of blockchain and IoT, along with a detailed overview of their exceptional use cases and real-world examples.

How is Blockchain Used in IoT?

So what makes blockchain merge well around IoT?

Despite its many advantages, the Internet of Things (IoT) is not without drawbacks. Connected IoT devices continue to rely on centralized infrastructure with minimal scalability. In addition, increased demand can result in overcrowded networks, low throughput, device dependability, and lack of supply chain transparency.

Additionally, unscrupulous hackers continue to target IoT devices. As a result, IoT can have potentially fatal consequences in the wrong hands, from breaches of cardiovascular devices and baby monitors to surveillance cameras and digital components in automobiles. Blockchain help IoT devices in overcoming these concerns by creating a safe, robust, and effective network.

Blockchain eliminates IoT’s reliance on centralized servers and single points of failure, which expose IoT devices to unscrupulous actors, thanks to its decentralized nature. Secondly, since all transactions are instantaneously visible on a shared, immutable ledger, blockchain IoT applications can improve supply chain transparency.

How Does Blockchain Technology Work For IoT Use Cases?

The three essential characteristics of blockchain technology in the form of a data structure are fundamental to the applications of blockchain IoT. The following are three fundamental aspects of blockchain technology that could assist IoT use cases:

1. Distribution

Through blockchain, data is spread across multiple computers on the network rather than in a single location. Consequently, hacking the monitoring system with many target devices is relatively challenging. Also, blockchain’s redundancy in storage improves data security accessibility.

IoT ecosystem users could quickly input and obtain their required data from various devices.

2. Immutability

The burglar may claim that video evidence recorded by surveillance cameras is fake, showcasing the blockchain IoT use cases. In these kinds of situations, the immutability of blockchain pops up, and it necessitates the detection of any modifications in the data that has been retained. As a result, the court could validate the burglar’s allegation by looking for evidence of data manipulation.

3. Decentralization

Although the security of IoT device data on blockchain networks is protected by distribution and immutability, decentralization could be a significant drawback. This could expose users’ sensitive data to third parties, and IoT blockchain use cases might include recording access records and permissions.

Big data storage can be prohibitively expensive due to blockchain’s distributed and decentralized nature. In this scenario, the central database would be stored in a central database, and data access records would be stored on a blockchain platform. As a result, users can obtain an immutable data structure that allows them to identify an individual accessing data and the time of the incident.

Now, keeping all of these advantages in mind, let’s take detailed knowledge of the top 9 Blockchain IoT use cases.
