At the recent cryptocurrency roundtable held by the U.S. Securities and Exchange Commission (SEC), discussions on decentralized finance (DeFi), code, and regulation have drawn widespread attention. SEC Chairman Atkins stated that engineers should not be held accountable for others' use of their code, emphasizing that developers play a role similar to that of providing neutral tools and should not be implicated due to third-party misuse of code. Commissioner Hester Peirce pointed out from a legal perspective that code falls under the category of free speech, protected by the First Amendment, and the SEC cannot regulate a publisher merely because someone has released code that is used for regulated activities, as this could infringe upon their constitutional rights. Erik Voorhees highly praised smart contracts, stating that compared to human regulators, smart contracts can automatically and accurately execute based on preset rules, reducing human intervention and subjective bias, representing a significant advancement in financial regulation methods. This series of viewpoints colliding brings new considerations for the regulatory direction and technological development of the cryptocurrency industry, which may influence the formulation of rules and innovative practices in the future DeFi space.
