Challenges in Designing Blockchain for Cyber-Physical Systems

With a population of 2.37 billiona and a GDP of more than $US30 trillion,b East Asia and Pacific's economic growth has seen a massive increase in cooperation and competition in recent years. To foster more growth in the region, there must be an automation of business processes that guarantees fair and open collaboration across multiple stakeholders. Cyber-physical systems (CPS) can enable automation across cyber and physical domains. In addition, blockchain technology offers auditability, transparency, and decentralization, thus showing promise to enable further developments in the region's economy. Combining these technologies would allow for a broad range of unprecedented possibilities. However, incorporating blockchains for CPS is challenging.
In the last couple of years, we have conducted cutting-edge research across Australian institutions—namely UNSW Sydney, QUT, and CSIRO's Data61—where we explored addressing these challenges in different verticals (domains) and horizontals (challenges), as seen in the accompanying figure. In this article, we discuss some of our work to share our experience in tackling the specific challenges of scalability, trust, and privacy.
