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.

Crowdfunding and Risk
Staff Working Paper 2023-28
David Cimon
Crowdfunding may enable unique products to reach the consumer market. I model a crowdfunding technology that publicly screens consumer demand early in the production process. In this model, entrepreneurs like crowdfunding for risky projects where demand is uncertain, but not for large, safe projects or for projects where production costs are uncertain.

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.

On the Fragility of DeFi Lending
Staff Working Paper 2023-14
Jonathan Chiu,
Emre Ozdenoren,
Kathy Yuan,
Shengxing Zhang
We develop a dynamic model to capture key features of decentralized finance lending. We identify a price-liquidity feedback: the market outcome in any given period depends on agents' expectations about lending activities in future periods, with higher future price expectations leading to more lending and higher prices in that period.

Janet Hua Jiang,
Francisco Rivadeneyra,
Yu Zhu
We review the nascent but fast-growing literature on central bank digital currencies (CBDCs), focusing on their potential impacts on private banks. We evaluate these impacts in three areas of traditional banking: payments, lending and liquidity and maturity transformation. We also take a broader look at CBDCs and highlight two promising directions for future research.

Potential benefits and key risks of fiat-referenced cryptoassets
Staff Analytical Note 2022-20
Hugh Ding,
Natasha Khan,
Bena Lands,
Cameron MacDonald,
Laura Zhao
Cryptoassets that reference a national currency (commonly known as stablecoins) aim to peg their value to the reference currency and typically use a reserve of traditional financial assets to maintain the peg. The market value of these fiat-referenced cryptoassets has grown more than thirtyfold between early 2020 and mid-2022. We explore some of their potential benefits and key risks.
