Hermes: An Open and Transparent Marketplace for IoT Sensor Data over Distributed Ledgers

Internet-of-Things (IoT) sensors have become cheaper and more ubiquitous than ever [1]. From smart thermometers to home assistants and smartphones, massive amounts of data are being streamed in real-time by sensors that are continuously connected to the web. However, these data tend to be amassed in private silos that are difficult to access. Many private companies and public institutions could build valuable services with these data but so far few solutions have been proposed on how to bridge this gap. In this paper we introduce Hermes, a platform for trading sensor data using distributed ledgers as intermediaries to add safeguards against malicious behavior.
