Data in IoT domains is significantly analysed and the information is mined as required. The results from the devices are then shared among the interested devices for better experience and efficiency. Sharing of data is rudimentary in any IoT platform which increases the probability of an adversary gaining access of the data. Blockchain, which consists of blocks that are connected together by means of cryptographic hashes, SHA256 being the most popularly used hash function in the blockchain network, is a newly adapted technology for secure sharing of data in IoT domains. A lot of challenges involving the integration for blockchain in IoT has to be addressed that would ultimately provide a secure mechanism for data sharing among IoT devices.
