Blockchain And Iot Based Secured Future City Architecture

Internet of Things (IOT) is the most significant revolutionary technology of this time. Because of the large volume and centralized architecture of IOT networks, privacy and security remain a major concern. On the other hand blockchain based methods provide decentralized protection and privacy. IOT and smart city technology developers can now create different forms of unified communications, data applications and solutions. This article analyzes the Internet of Things protection technologies by incorporating blockchain IOT applications. To address both cryptographic security and privacy concerns, the proposed IOT-based smart city architecture uses BC technologies. Furthermore, BC has a very low overhead on the IOT network. The new system is a blockchain based fully distributed access management framework for IOT. This article discusses the similarities and differences between blockchain and IOT technologies, as well as a general reference framework that can be used to build a variety of blockchain based community IOT applications.
