Now days, Internet of Things (IoT) and Blockchain are new buzzwords across the world. IoT has substantial impact on human life. IoT consists of various heterogeneous devices that are communication over the globe. All IoT applications are producing huge amount of data daily, which raises the concerns about its security. Although there exist centralized access management technologies but there are numerous technical limitations to manage these resources globally. On the other hand, Blockchain, which is based on decentralized and distributed approach, maintains reliable archives of data at different locations with the help of tamper resistant ledger. Blockchain can address the data security concerns in IoT networks. This paper reviews the concepts of IoT, blockchain and advantages of incorporating Blockchain with IoT.
