High-Confidence Computing (HCC) relies on interdisciplinary methodologies to realize secure and trusted software, precise and process-traceable algorithms, and self-evolving designs that can adapt to new environments and support new applications. Internet of Things (IoT) systems possessing HCC properties can provide collaborative services that are otherwise impossible as security, traceability, accountability, reliability, robustness, extensibility, adaptivity, and self-evolution are all desirable and equally-important properties of modern connected systems such as smart cities. This talk intends to answer the following questions: what is high-confidence computing and how to realize high-confidence IoT via blockchain technology. We will introduce an architecture to demonstrate our exploratory studies regarding how to integrate state-of-the-art techniques to build a blockchain-enabled high-confidence IoT and present our own effort towards its realization. Open research challenges will also be discussed.
