Decentralized identity (DID), the idea of giving users complete control over their identity-related data, is being used to solve the privacy tension in the identity management of decentralized applications (Dapps). While existing approaches do an excellent job of solving the privacy tension, they have not adequately addressed the accountability and Sybil-resistance issues. Moreover, these approaches have a considerable gas overhead, making them impractical for Dapps.
