【Abstract】The space of Internet-of-things has exploded, with billions of interconnected devices ranging from mainframes to refrigerators and thermostats. These devices offer the promise of greater automation and control, and the ability for micro-level transactions that did not exist before. The advent of blockchain offers an intriguing path to managing distributed transactions in this new ecosystem. The use of blockchain in IoT applications is relatively new, especially at the lower end of the computing spectrum. Consequently, the roadmap for the future is unclear, and there are several challenges and questions that need to be addressed, such as trust, security, and efficiency. In this paper, we survey some of the promising applications that are being implemented including supply chains, smarter energy, and healthcare. We outline strategies for overcoming many of the challenges, which should lead to successful adoptions of blockchain for IoT. Finally, we sound a cautionary note on the potential cybersecurity implications in using IoT devices, including increased attack surfaces and device vulnerabilities. (C) 2019 Elsevier B.V.
