Challenges and Approaches to Regulating Decentralized Finance

Decentralized finance (DeFi) is an ecosystem of financial applications that are built on top of blockchain networks. DeFi aims to create an open-source, permissionless, and transparent financial system that operates without any central authority. Instead, a smart contract—which is a self-executing contract with the terms of the agreement between transacting parties written into lines of code—replaces financial institutions in the transaction. As a result, DeFi is available to everyone with reliable access to electricity and Internet connectivity. It also serves as a form of non-custodial finance since users maintain full control of their assets and transact through smart contract programs that facilitate peer-to-peer interactions. While DeFi presents huge opportunities, it also poses significant risks to traditional finance ecosystems, including the use of stablecoins and the absence of a know-your-customer framework. This essay argues that for DeFi to secure credibility, it needs to be adequately regulated in a way that aligns with how the technology works.
