   Abstract. In a cyber-physical system (CPS), computing elements coordinate and
   communicate with sensors, which monitor cyber and physical indicators, and ac-
   tuators, which modify the cyber and physical environment where they are run.
   Current CPS ecosystems rely on centralised, brokered communication models,
   otherwise known as the client-server paradigm. All devices are identified, au-
   thenticated and connected through cloud servers and the data collected by the
   devices is stored in the cloud for further processing. While this model has con-
   nected generic computing devices for decades and will continue to support small-
   scale CPS networks as we see them today, it will not be able to respond to the
   growing needs of the large-scale CPS ecosystems of tomorrow with billions of
   connected devices. Cloud servers will remain a bottleneck and point of failure
   that can disrupt the entire network. This is especially important as critical ser-
   vices and infrastructure such as healthcare, electric grids, logistics, transportation
   become dependent on CPS. The current stove-piped architecture has also created
   isolated data silos, where users have limited control over their data and how it is
   used. Users have to trust the cloud and application providers and have no choice
   but to rely on their promises of security and availability.

   In this talk we will explore how Blockchain (BC) technology has the potential to
   overcome the aforementioned challenges. BC is an immutable timestamp ledger
   of blocks that is used for storing and sharing data in a distributed manner. The
   stored data might be payment history, e.g. Bitcoin, or a smart contract or even
   personal data. In recent years, BC has attracted tremendous attention from prac-
   titioners and academics in different disciplines (including law, finance, and com-
   puter science) due to its salient features which include decentralization, immuta-
   bility, auditability and security and privacy. The talk will specifically consider
   three key aspects of CPS which include: (i) Internet of Things; (ii) Intelligent
   Transportation; and (iii) Supply Chain. The talk will explain relevant concepts,
   review the state-of-the-art, present representative solutions and discuss open
   challenges.
