Advances in blockchain technology have led to new applications that aim to eliminate central systems, to improve transparency and user control in transactions whiledealing with the privacy and security challenges. In this thesis, a system which enables users to control their private data and to share chosen data to other parties usingsecure computation techniques is reviewed. Then, we present a blockchain-based digital identity system depending on this architecture. This system ensures that identity information is shared and transmitted confidentially in accordance with their own consent.
