• Three things we learned about the Lynx payment system

  Staff Analytical Note 2023-14 Nikil Chande, Zhentong Lu, Hiru Rodrigo, Phoebe Tian

  Canada transitioned to a new wholesale payment system, Lynx, in August 2021. Lynx is based on a real-time settlement model that eliminates credit risk in the system. This model can require more liquidity; however, Lynx’s design allows Canada’s wholesale payments to settle efficiently.

• 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.

• Understanding DeFi Through the Lens of a Production-Network Model

  Staff Working Paper 2023-42 Jonathan Chiu, Thorsten Koeppl, Hanna Yu, Shengxing Zhang

  We develop a production-network model to capture how decentralized finance (DeFi) has evolved across different sectors of financial services. The model allows us to measure the value added by different DeFi sectors and to study how the connections across the sectors influence token prices.

• 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.

• Reviewing Canada’s Monetary Policy Implementation System: Does the Evolving Environment Support Maintaining a Floor System?

  Staff Discussion Paper 2023-10 Toni Gravelle, Ron Morrow, Jonathan Witmer

  At the onset of the pandemic, the Bank of Canada transitioned its framework for monetary policy implementation from a corridor system to a floor system, which it has since decided to maintain. We provide a comprehensive analysis of both frameworks and assess their relative merits based on five key criteria that define a sound framework.

• How Banks Create Gridlock to Save Liquidity in Canada's Large Value Payment System

  Staff Working Paper 2023-26 Rodney J. Garratt, Zhentong Lu, Phoebe Tian

  We show how participants in Canada’s new high-value payment system save liquidity by exploiting the new gridlock resolution arrangement. The findings have important implications for the design of these systems and shed light on financial institutions’ liquidity preference.
