Internet of Things is creating new opportunities and providing a competitive advantage for different fields. One of the key challenges of IoT world is security. In this article, our attempt is to critically view the use of Blockchain Technology to secure IoT. Blockchain is a distributed database technology that provides very hard to tamper, ledger records. It allows storage of all transactions into immutable records and every record distributed across many participant nodes. The security comes from use of strong public key cryptography, strong cryptographic hash and complete decentralization. In this project, we develop an IoT application to monitor temperature and store it securely in the blockchain. We use Raspberry Pi 3 Model B for implementing the project. The prototype can be extended to any type of application.
