Internet reports that according to Protos, U.S. prosecutors have filed a motion to prevent expert witnesses of Tornado Cash founder Roman Storm from appearing in court. Prosecutors call them "Trojan horses" that waste jury time and confuse jurors 'understanding of privacy, token economics and KYC. This means Roman Storm's defense team needs more time to respond to a large number of documents that attempt to eliminate eight defense arguments, and prosecutors even oppose extending the two-day period. In addition, it is reported that the U.S. Department of Justice has dropped the "unlicensed money transfer" charge against Roman Storm and no longer refers to Tornado Cash as a "financial institution" but retains the money laundering charge. It is reported that Roman Storm's trial is expected to begin in New York on July 14, and Vitalik and the Ethereum Foundation have expressed support for it.
