This platform can provide easy methods for treating sensors because it has a feature by extended XMPP. In addition, this platform is implemented by XMPP, so this platform can spread data for many clients. We focused on this platform; we thought the extend the system to realize an open-data marketplace. For this reason, data will have a huge value better than now, for example, such as monetary value in the future world. Then, we focus on blockchain as an effective technology. In addition, the IoT marketplace using blockchain is implemented now. We focus on realizing open-data commerce by collaborating with SOXFire and the blockchain marketplace. In this paper, we developed a system to integrate those. Last, we tried to do preliminary experiments to evaluate feasibility by measuring loads of a machine resource and delay time., SOXFire is the IoT platform based on pub/sub-model.
