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 a Dutch judge at ‘s-Hertogenbosch court on May 14.

The sentencing came despite Tornado Cash being a non-custodial crypto mixing protocol — meaning that the funds that go through the protocol are never held or controlled by it.

Despite having no control over the funds, the developer was found guilty after first being jailed in the Netherlands in August 2022, shortly after Tornado Cash was blacklisted by the U.S. government.

However, the length of Pertsev’s sentencing is as yet unknown.
