A blockchain-based IoT data marketplace

The (IoT) is growing steadily, and so is the number of data that is generated by (IoT) devices. This makes it difficult to find and leverage relevant data (and data sources) without a data marketplace. Such a marketplace provides a platform to enable different parties, e.g., sensor operators and service providers, to trade their data. Today, most data marketplaces are based on centralized solutions, which may become a single point of failure and come with expensive infrastructure, trust problems, and privacy issues. Therefore, we propose the application of blockchain technology to implement a data marketplace for the IoT. Within the proposed marketplace, smart contracts are used to implement various functionalities and enforce the rules of the data exchange. The marketplace also includes a proxy, a broker, and (GUIs) to enable data trading. To show the applicability of the proposed data marketplace, we analyze the costs arising from the utilization of smart contracts.
