Anonymous Credentials: Secret-Free and Quantum-Safe
An anonymous credential mechanism is a set of protocols that allows users to obtain credentials from an organization and demonstrate ownership of these credentials without compromising users’ privacy. In this work, we construct the first secret-free and quantum-safe credential mechanism. -
Understanding DeFi Through the Lens of a Production-Network Model
