Canada central bank assesses innovations and challenges of DeFi

The Bank of Canada published a staff note on decentralized finance (DeFi) on Oct. 17, assessing the innovations that made it popular and the challenges and risks associated with its use.

The staff note described DeFi as a multi-layered structure, with the Ethereum blockchain serving as the bottom layer (or settlement layer). Developers construct a variety of tools and services on top of the main blockchain, including tokenization, lending and borrowing services, and much more.

The staff note shed light on the rise in popularity of the DeFi ecosystem starting in 2020 and how it became an integral part of the crypto economy, with billions in volume over the next few years. The popularity of the ecosystem took a dip starting in 2022 with the collapse of multiple key crypto platforms with significant DeFi exposure, including Terra.

Talking about the key features of the decentralized ecosystem, the staff note lauded DeFi’s “composability,” which allows the apps and services in the ecosystem to interconnect. The Bank of Canada note highlighted three of the key areas where DeFi can transform the financial system:

Apart from the key DeFi innovations that can transform the traditional financial system, the staff note also talked about the challenges and risks associated with the DeFi ecosystem, claiming that “despite its innovations and possibilities, the overall economic benefits of DeFi remain limited.”
