Security in the Internet of Things with Blockchain

The Internet of Things (IoT) is the most emerging technology of the last decade since the numberof smart devices, and related technologies are growing rapidly in both industrial and researchaspects. With the advent of smart devices, the Internet of Things has emerged as an area ofincredible impact, potential and growth, these IoT devices are easily compromised. Typically,these IoT devices are limited in computing, storage, and network capacity, and are thereforemore vulnerable than other endpoint devices such as smartphones, tablets, or computers.Blockchain (BC) methods are one of the best technologies in IoT environments, blockchain hasattracted many people as a key technology to build trust networks and implement valuecommunication. Blockchain's features, such as no, consensus mechanism, data encryption andsmart contracts, are suitable for creating IoT systems to avoid risk and reduce transaction costs.As a decentralized and transparent database platform, blockchain has the potential to bring IoTsecurity to the highest level. Blockchain's responsibility in the Internet of Things is to provide away to transfer protected data through IoT devices. In this article about blockchain technology,how to secure the transmission of the Internet of Things and what are the challenges in thistechnology
