Consumer data are an important driver of firms’ marketing decision-making. While some of the data comes from the firm’s own customers, firms often require data from third-party providers on consumer activities outside the firm. Current data markets are dominated by large-scale intermediaries that use the data to maximize their own profits. Meanwhile, firms depend on them to get access to the data, and consumers who produce the data are rarely compensated and have limited control as to how the data are used. In light of the impending shift away from third-party tracking cookies, we present a novel approach to establishing a blockchain-based data marketplace where buyers and sellers directly trade data at market value, eliminating the need for data brokers and providing consumers full control over the use of their data. We discuss the shortcomings of current data markets and the opportunities afforded by blockchain-based data marketplaces. To lead the research efforts for this profound transformation, we present a proof-of-concept blockchain data marketplace platform app that we developed for the research community to further investigate data marketplaces. We provide guidelines for experimentation on this platform and describe preliminary results. We further identify research questions stimulated by such marketplaces that need to be answered to prepare for this paradigm shift.
