Due to its indisputable nature and associated benefits of security and privacy, blockchain (BC) has attracted a lot of attention. BC has the potential to address IoT's shortcomings with data security and privacy. Due to the enormous scale and distributed nature of IoT networks, IoT security and privacy continue to be a significant concern. Because of sophisticated algorithms, security overhead, throughput, and latency, the BC described solutions are not workable to construct IoT applications. The proposed Blockchain based IoT is designed to handle mainly privacy and security threats, though consider many IoT devices resource-constraints.
