Towards Trustworthy and Independent Data Marketplaces

Data is the new oil. In the past years the awareness about benefits of data has increased. A growing number of sectors recognize the opportunities from data. On the one hand it is very difficult for many researchers and enterprises to obtain data and on the other hand for those who collect data, the problem is, how to draw to additional profit from the data beyond its obvious purpose. To tackle this problem, we propose a common data sharing platform, where the data producers can sell data and the others can consume it. Just like any other online marketplace a data marketplace is a platform which enables convenient buying and selling of products- in this case "data". Blockchain enables businesses to be decentralized and more secure. Thus, in this paper we explore an approach to combine data marketplaces and blockchain for fair and independent data marketplaces.
