In this paper, we review the literature on blockchain technology and its applications in enhancing cyber security and resilience in critical infrastructures such as energy, health, and finance. We discuss the main challenges and opportunities of blockchain technology for securing data, devices, and networks in these domains. We also identify the key research gaps and directions for future work. We conclude that blockchain technology can provide a novel and promising solution for improving cyber security and resilience in critical infrastructures, but it also requires further development and evaluation to address the technical, social, and regulatory issues involved.
