Golden Finance reports that on December 27, the U.S. Internal Revenue Service (IRS) announced new regulations defining certain decentralized finance (DeFi) protocols as brokers, requiring them to fulfill customer identity verification (KYC) obligations, which has sparked strong opposition from the cryptocurrency industry. This regulation is expected to impact up to 875 DeFi brokers and 2.6 million taxpayers. Legal experts criticize the rule as potentially overstepping authority and infringing constitutional rights. Paradigm Vice President Alexander Grieve has called on the new 'crypto-friendly Congress' to pass the Congressional Review Act (CRA) to abolish this regulation. The Blockchain Association stated that this rule is 'the last-ditch effort to push the U.S. cryptocurrency industry overseas' and indicated that action will be taken to combat it. Previously, reports indicated that the IRS required 'DeFi brokers' to collect user transaction information.
