• Analysis of DeFi Oracles

  Staff Discussion Paper 2024-10 Xun Deng, Sidi Mohamed Beillahi, Cyrus Minwalla, Han Du, Andreas Veneris, Fan Long

  Oracles are constructs used in decentralized finance to price assets relative to each other. However, oracles contain defects that could lead to manipulation attacks. Such attacks exploit pricing models embedded within oracles to defraud creators and users. We automatically verify defects, which if mitigated, improves the security of digital currency.

• Anonymous Credentials: Secret-Free and Quantum-Safe

  Staff Working Paper 2023-50 Raza Ali Kazmi, Cyrus Minwalla

  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.

• Privacy-Preserving Post-Quantum Credentials for Digital Payments

  Staff Working Paper 2023-33 Raza Ali Kazmi, Duc-Phong Le, Cyrus Minwalla

  Digital payments and decentralized systems enable the creation of new financial products and services for users. One core challenge in digital payments is the need to protect users from fraud and abuse while retaining privacy in individual transactions. We propose a pseudonymous credential scheme for use in payment systems to tackle this problem.

• A central bank digital currency for offline payments

  Staff Analytical Note 2023-2 Cyrus Minwalla, John Miedema, Sebastian Hernandez, Alexandra Sutton-Lalani

  Offline functionality is a key consideration for a potential CBDC. We describe the different types of offline functionality based on their duration outside of network connection—either intermittent (for short periods) or extended (for longer periods). We discuss the advantages and drawbacks of each and consider implications for end-user devices, system resilience and universal accessibility.
