Blockchain Enabled Data Marketplace -- Design and Challenges
This addresses the problem of improving data trading platforms for companies and users, but it appears incremental as it builds on existing blockchain concepts without a novel breakthrough.
The paper tackles the inadequacies of current data marketplaces by proposing a blockchain-enabled solution that aims to fulfill properties like fairness, efficiency, security, privacy, and regulatory adherence, though no concrete results or numbers are provided.
Data is of unprecedented importance today. The most valuable companies of today treat data as a commodity, which they trade and earn revenues. To facilitate such trading, data marketplaces have emerged. Present data marketplaces are inadequate as they fail to satisfy all the desirable properties - fairness, efficiency, security, privacy and adherence to regulations. In this article, we propose a blockchain enabled data marketplace solution that fulfills all required properties. We outline the design, show how to design such a system and discuss the challenges in building a complete data marketplace.
