As Canada continues to engage in a dialogue to develop the approach to modernizing its core payment systems, we analyze the core payment systems that exist in countries around the world. We study payment systems in 27 jurisdictions, encompassing a broad range of geographic regions, through three...

The payments landscape in Canada is rapidly changing and will continue to evolve, fuelled by strong and persistent drivers. In Canada, the Canadian Payments Association (CPA) is on a path to modernize Canada's core payment systems. This paper contributes to the discussion in three ways. First,...

This paper presents OVer, a framework designed to automatically analyze the behaviour of decentralized finance (DeFi) protocols when subjected to a "skewed" oracle input. OVer firstly performs a symbolic analysis on the given contract and constructs a model of constraints. Then, the framework...

We frame the wide spectrum of possible system architectures for an online retail central bank digital currency (CBDC) and identify a promising architecture well-suited for basic payments. We select OpenCBDC 2PC, a representative system design that fits this architecture and analyze it using a...
