The document discusses the growing market for sensor data from IoT devices. It notes that the global IoT sensor market reached $600 billion in 2015 and is expected to reach $1.2 trillion by 2019. Though corporations and governments own 90% of sensors, only 10% of the data they produce is valuable to third parties, representing a potential $30-90 billion secondary market. The document introduces Databroker DAO, a blockchain-based marketplace that aims to unlock this value by enabling the monetization and sharing of sensor data between primary owners and secondary buyers.
