This example makes use of a Raspberry Pi device which is a Single Board Computer (SBC).
The Raspberry Pi is a SBC developed as a low-cost computer to promote computer education but has also gained much more popularity as a tool of choice for building IoT platforms.
How Distributed Ledger Technology Secures Connected Devices (Part 2)
You may be able to use earlier models too, but those have not been tested: Raspberry Pi Model B In , an example will be discussed where a Raspberry Pi will be used as an IoT device connected to the Ethereum blockchain and will act in response to a smart contract invocation.
This can be done by using NOOBS which provides an easy method of installing Raspbian or any other operating system.
This can be downloaded and installed from the link https://www.raspberrypi.org/downloads/noobs/.
Alternatively, only Raspbian can be installed from the link https://www.raspberrypi.org/downloads/raspbian/.
Another alternative can also be used to install a minimal non-GUI version of Raspbian OS.
For this example, NOOBS has been used to install Raspbian, as such the rest of the exercise assumes Raspbian is installed on the SD memory card of the Raspberry Pi.
Why This Matters for Blockchain Technology
The command output in the following screenshot shows that which architecture the operating system is running on.
In this case, it is armv71; therefore ARM-compatible binary for Geth will be downloaded.
The platform can be confirmed by running the command uname -a in a terminal window in Raspberry Pi Raspbian operating system.
Raspberry Pi architecture Once the Raspbian operating system is installed, the next step is to download the appropriate Geth binary for the

Conclusion
IoT blockchain experiment represents one of the many innovative layers that make blockchain technology so powerful and transformative. As distributed systems continue to evolve, a solid understanding of these core concepts becomes increasingly valuable — not just for developers, but for anyone building, investing in, or working alongside blockchain-powered systems.
Whether you are just starting your blockchain journey or deepening existing expertise, mastering these fundamentals gives you the tools to think clearly about decentralized systems and make smarter decisions in this rapidly evolving space.
