New Privacy Practices for Blockchain Software

Abstract

The benefits of blockchain technologies for industrial applications are unquestionable. However, it is a considerable challenge to use a transparent system like blockchain and at the same time provide privacy to sensitive data. Privacy technologies permit conducting private transactions about sensitive data over transparent networks, but their inherent complexity has been overwhelming for many developers. Closing the gap between developers and privacy-preserving technologies would help to the full adoption of the privacy by design framework for blockchain software. To this end, in this paper we present the software tools we have implemented to bring complex privacy technologies closer to developers and facilitate the job of implementing privacy-enabled blockchain applications.
