Abstract
The Internet offers unprecedented opportunities to collect large amounts of personal data at low cost. Typically, it is not only the data collection process but also their further use which is opaque to the individuals. Blockchain technology promises to return Internet users control over their personal data. In this chapter we present and discuss Wibson, a decentralized data marketplace based on the blockchain that provides a way for individuals to control and monetize their personal information in a trusted environment. By using a token and blockchain-enabled smart contracts Wibson allows data sellers and buyers to interact while allowing them to keep their desired level of anonymity. This chapter is based on qualitative interviews and the thorough analysis of the technical documentation. We describe the underlying rationale and functioning of Wibson and provide suggestions for future research at the intersection of blockchain and privacy.
