Summary

In this paper we describe a practical digital identity project of a global scale, which solves a number of privacy and scalability problems using the concepts of anony- mous credentials and permissioned blockchains. Even though both ideas have been known and developed for a number of years, our system appears to be the first amalgamation. The prototype has been developed, tested, and published as open source.
