Short Review on Blockchain Technology for Smart City Security

Abstract

Over the past 22 years, our world has increasingly become interconnected, revolutionizing how information is shared and how people interact with one another. But even with this kind of progress, there are challenges that need to be dealt with, to secure a better future for everyone. Things like climate change pose a serious danger to the world. And as part of the solution, technology is being leveraged to build smart cities that can facilitate smart living in futuristic urban environments. This paper primarily focuses on how blockchain technology could be used to secure smart cities that are evolving. The paper puts emphasis on the feasibility and advantages of deploying decentralizing security frameworks using blockchain systems to combat cyber threats in smart cities.
