Pertsev has been under arrest in the Netherlands since August 2022 after the United States government blacklisted Tornado Cash.
Alexey Pertsev, the developer of the cryptocurrency mixing protocol Tornado Cash, has been found guilty of money laundering, raising potentially severe implications for open-source code developers.
Pertsev was found guilty of money laundering by Dutch judges at the s-Hertogenbosch Court of Appeal on May 14. The developer was sentenced to five years and four months in prison for allegedly laundering $1.2 billion worth of illicit assets on the platform.
The sentencing came despite Tornado Cash being a noncustodial crypto mixing protocol — meaning that the funds that go through the protocol are never held or controlled by it.
