Blockchain and Internet of Things (IoT): A Disruptive Integration

The combination of internet of things (IoT) and blockchain can propose innovative applications in different smart networks. Due to the various applications in IoT ecosystem providing a secure network with high quality of privacy is so important. Blockchain, which is a decentralized and distributed ledger technology, can be a proper solution. In addition, various terms and conditions of different services in IoT need to be guaranteed, where a smart contract feature in blockchain can be used. In this paper, we studied the integration of blockchain in IoT networks applications. This integration is discussed in different use cases such as smart city, smart energy, smart home, smart industry, healthcare, agriculture, unmanned aerial vehicles (UAVs). The advantages of blockchain application in each of these areas is proposed in the paper. The combination and integration of blockchain and IoT can provide significant development in smart networks.
