What is Blockchain IoT and How It make us more Smarter in 2023

Blockchain IoT

When it comes to the Internet of Things (IoT), there are a lot of different possibilities for what blockchain iot can bring to the table. Blockchain is a sweeping term encompassing a vast range of applications and use cases. In its simplest form, Blockchain is a decentralized digital ledger that can record anything of value.

This could include everything from financial transactions to voting records. But what does this mean for the internet of things? Can Blockchain be used for IoT?

Is there potential for Blockchain to revolutionize how we interact with the physical world around us? Let’s take a closer look.

What Is Blockchain?

At its core, Blockchain is a digital ledger that is decentralized and tamper-proof. This means that it can record any transaction or data without the need for a third party. Blockchain is also transparent, meaning that anyone with access to the ledger can see the transactions that have taken place. This makes it a secure and trustworthy way to track information.

By creating a secure and distributed ledger for transactions, Blockchain could help create trust and transparency between devices in a way that wasn’t possible before. This could be especially useful in industries where you data collect data and share it between many parties, such as healthcare or manufacturing. 

In addition, blockchain technology manages access to IoT devices and creates digital identities for objects.

So, all of this helps pave the way for a future where more things connect to the internet and can communicate with each other.

How Does Blockchain Apply to IoT?

There are a few key ways that Blockchain uses to improve IoT:

1. Trust and transparency:

As mentioned earlier, Blockchain is a secure and transparent way to track information. This could be useful for ensuring that data collected by IoT devices is accurate and trustworthy.

2. Decentralized data management:

One of the key benefits of Blockchain is that it is decentralized. This means there is no single point of failure, and the network is less likely to go down. In the context of IoT, this could mean that devices would be able to continue communicating with each other even if one or more of them were to go offline.

3. Digital identities:

Another key application of Blockchain is digital identity. This refers to creating a unique identifier for an object or person. With Blockchain, however, it would be possible to create a digital identity for every object in the world. You can track and manage access to IoT devices and keep track of objects’ movements and history.

4. Log operational maintenance data:

Blockchain log operational data from IoT devices. This could include data on energy consumption, resource use, and other performance metrics. This data helps optimize operations and improve efficiency.

For example, imagine if you could track your home’s energy use in real-time. With Blockchain, you would be able to see exactly how much power each device in your home is using and how much it’s costing you. You could then use this data to make informed decisions about optimizing your energy usage.

5. Freight transportation:

You can use Blockchain technology to streamline freight transportation. Blockchain could help reduce the amount of paperwork and bureaucracy involved in the freight transportation process by creating a secure and transparent system for tracking shipments.

Real-Life Projects

Just in case you still don’t see how blockchain technology is about to revolutionize our physical world, here are some examples of real-life projects that are already in development:

  • IoT-enabled smart cities

Several cities are already working on projects that use Blockchain and IoT to create smarter, more connected cities. For example, the city of Dubai is developing a project that will use Blockchain and IoT to manage traffic congestion, energy consumption, and other aspects of city life. Blockchain iot is also solving the challenges of smart city.

  • IoT-enabled healthcare

Healthcare is another industry that stands to benefit from the integration of Blockchain and IoT. For example, Blockchain could create a secure system for tracking patient data. This could help improve the security and accuracy of patient data and reduce the risk of data breaches.

  • IoT-enabled supply chains

Supply chains are another area where Blockchain could improve efficiency and security. For example, Blockchain could create a secure system for tracking shipments. This could help reduce the amount of paperwork and bureaucracy involved in the freight transportation process.

The potential applications of blockchain technology are vast and far-reaching. Hence, there are many possibilities for how Blockchain can improve IoT. These are all the benefits of blockchain use. 

With more and more things connected to the internet, it is important to have a secure and trustworthy way to track data. Blockchain has the potential to fill this role and revolutionize the way we interact with the world around us.

Which Blockchain Is Best For Iot?

You can use different blockchains for the Internet of things. Some of the most popular include;


Ethereum is a blockchain platform that allows for the development of decentralized applications. This makes it a good choice for IoT applications that need to be scalable and secure. Most of the current IoT applications are built on the Ethereum platform.


IOTA is a blockchain-based platform that focuses on the internet of things. It allows for the creation of secure and scalable IoT applications. The IOTA Foundation is also working on a Tangle project, which is designed to provide a secure way to handle transactions in IoT applications.

Hype ledger Fabric:

In 2017, Hyperledger Fabric was the most popular blockchain platform for enterprise applications. With its ability to handle large volumes of transactions, Hyperledger Fabric is a good choice for blockchain-based IoT applications.

It is important to choose the right Blockchain for your IoT application. Each Blockchain has its strengths and weaknesses, so it is important to choose one that will suit your needs. 

Bottom Line:

The bottom line is that Blockchain and IoT are a natural fit, and combining the two technologies can revolutionize many aspects of our lives. As more and more businesses and cities begin to experiment with these technologies, we can expect to see even more amazing things happening in the world of IoT.
