Internet of things (IoT) is a collection of various types of devices that has sensors and connected to each other over a network. This technology was first implemented in 1982 and today, especially with the spread of the internet, it is frequently used in many areas such as identification and monitoring technologies, wired and wireless sensors and distributed information systems. As its usage areas have expanded, this technology has started to be used for data collection purposes. On the other hand, in an era where workable data has gained significant value, collecting data via the IoT has become an important endeavor not only for researchers in the field of data, but also for those who want to gain commercial benefits from this data. This situation has revealed the need to market such data in a reliable and healthy way. Due to its features such as transparency, immutability of records and decentralization, blockchain technology stands out as an effective and safe method to meet this need. In this work, with the help of SysML diagrams, it is examined that how an ideal blockchain-based data trading platform should be. In this direction, first the components of the platform were determined and the relations between these components were analyzed. In addition, the requirements needed for this system to work safely and effectively have been defined. Moreover, how these requirements can be met is demonstrated through an example scenario.
