Developing an Integrated IoT Blockchain Platform: A Demonstrator
Advances in Intelligent Systems and Computing
Ensuring the integrity and security of an Internet of Things (IoT) system, and maintaining and updating the firmware driving its devices, becomes critical as the number of nodes, sensors, actuators and control loops increases. The security of IoT can be addressed by deploying blockchain technology. The feasibility of building a blockchain-based IoT on a low-cost microcontroller is demonstrated. This is achieved by implementing an Ethereum node on Raspberry Pi 3 controlling an LED. The LED data of turning ON and OFF by the user are collected and stored on a smart contract. The interaction with the smart contract is performed by a DApp called, Status, developed based on Light Ethereum Subprotocol (LES). The feasibility of the concept was successfully demonstrated, showing the potential of blockchain technology in developing more secure IoT systems.
