【Cryptocurrency lobbying group Blockchain Association sues the IRS over 'DeFi Broker' regulation】Golden Finance reports that the U.S. cryptocurrency lobbying group (Blockchain Association) announced that it has filed a lawsuit against the new 'broker' regulations passed by the IRS and the Treasury Department. The IRS and Treasury have exceeded their statutory authority by expanding the definition of 'broker' to include providers at the front end of DeFi transactions, even though they do not execute trades. This not only infringes on the privacy rights of individuals using decentralized technology but also pushes emerging technologies overseas.
