Smart contracts are a transformative technology, enabling secure, automated, and transparent transactions without intermediaries. Despite their potential, their application in Internet of Things (IoT) use cases remains underexplored, leaving a gap in understanding how these contracts can enhance IoT ecosystems through secure device communication, data validation, and automated processes.
This site provides a comprehensive tutorial tailored for embedded system and IoT developers, offering step-by-step guidance on learning about smart contracts and integrating them into IoT applications to unlock their full potential. It can be used as a graduate or undergraduate course on the domain of computer science and computer engineering. It also presents a use case example in which a smart contract is used to control a raspeberry pi that could be used for automating the payment of car renting.
