New IRS rules classifying DeFi protocols as brokers have ignited a storm in the crypto world. Announced on Dec. 27, these regulations demand Know Your Customer disclosures from platforms facilitating digital asset transactions, affecting up to 875 DeFi brokers. Critics argue the IRS is overreaching, with legal experts like Jake Chervinsky calling the rule an "unlawful" move. The Congressional Review Act could allow the new Congress to overturn these regulations. Advocacy groups vow to fight back, fearing the rules could push the US crypto industry offshore. The IRS estimates the changes will impact 2.6 million taxpayers.
