In the last years, identity management solutions on blockchain were proposed as a possible solution to digital identity management problems. However, they are still at an early stage, and further research needs to be done to conclude whether identity systems could benefit from the use of blockchain or not. Motivated by this, we investigate blockchain-based identity management solutions to give the reader an overview of the current status and provide a better understanding of the pros and cons of using such solutions. We analyze ten of the most known implementations, with a focus on privacy and security aspects. Finally, we identify existing challenges and give new research directions.
