The DeFi Education Fund (DEF) is asking U.S. courts to consider the nature of blockchain technology when determining cryptocurrency users’ privacy rights under the Fourth Amendment, which protects people from unreasonable government searches and seizures. DEF filed an amicus brief with the U.S. Court of Appeals for the First Circuit on Oct. 20 in support of James Harper’s appeal of the Internal Revenue Service (IRS) of a 2017 court order that forced Coinbase to hand over more than 14,300 users The data.
