Internet of Things (IoT) plays an important role in the development of various fields. The increasing scale and scope of applications make a great demand of IoT data exchange in recent years. Meanwhile, a number of IoT data exchange platforms which dedicated to connecting various and distributed data sources are emerging. In such a platform, service providers can search and exchange the data sets that they need. However, the centralized infrastructure cannot provide enough trust as the third-party intermediaries for data exchange. As a result, most platforms unable to satisfy the complex requirements due to few institutions and individuals are willing to share their IoT data sets in such an untrustworthy environment. This paper proposes a decentralized solution based on the blockchain for IoT data trusted exchange. Specifically, In this paper, the basic principles of blockchain and corresponding key technologies are expounded through in-depth analysis of three main reliable requirements in IoT data exchange. Besides, this paper provides an architecture of above solution and detailed design of its main trust component. Finally, it realizes a prototype by using Ethereum blockchain and smart contracts and presents its auditable, transparent, decentralized features visually.
