On design issues and architectural styles for blockchain-driven IoT services

We can perceive the advent of smart living spaces attributed to the fast emerging of IoT (Internet of Things) technologies. By combining with the blockchain technology, many innovative business models can be brought into reality. This paper aims to report our recent progress in investigating the architectural issues for realizing blockchain-driven IoT services. In particular, we present and discuss four typical architectural styles for such services. A preliminary evaluation against different styles is also provided to compare the given styles.
