Blockchain, a distributed database technology attracts intensive attention recently. It was first described in 1991 by Stuart
Haber and W. Scott Stornetta, in order to prevent tampering for document timestamps. After that, Satoshi Nakamoto
conceptualized this technology with his work, a peer-to-peer electronic cash system named as Bitcoin. Due to its authenticity, user
anonymity and data immutability; this technology has also been applied to different areas ranging from finance, supply-chain
managements to social services. In this paper, we propose a blockchain based application for trading data, collected from IoT
devices. Our application enables the sellers to commercialize their data in exchange of the currency produced by the application.
The application also utilizes smart contracts to establish trust between both sides of the exchange. Furthermore, we discuss the
security and reliability of the system components
