The U.S. cryptocurrency lobbying group (Blockchain Association) has stated that a lawsuit has been filed against the new 'broker' regulations introduced by the IRS and the Treasury Department. The IRS and the Treasury Department have exceeded their statutory authority by broadening 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.
