As a long-term crypto investor with a strong belief in the potential of decentralized finance (DeFi) and privacy-preserving technologies, I find the conviction of Tornado Cash developer Alexey Pertsev to be a concerning development. While it’s crucial that we root out criminal activities within the crypto ecosystem, it’s equally important not to unfairly blame developers for the actions of anonymous users who intentionally misuse open-source tools.


Developer Alexey Pertsev of Tornado.cash has been determined responsible for laundering approximately $1.2 billion worth of illegitimate cryptocurrencies through the blacklisted mixer service.

A Dutch court handed down a sentence of 64 months in prison to Pertsev, a 31-year-old Russian residing in the Netherlands. The lawyers for this individual have the option to file an appeal within a fortnight following the verdict.

Tornado Cash Developer’s Conviction

In August 2022, a developer was initially detained in the Netherlands. This action came after the US government prohibited the use of Tornado Cash due to its alleged connection to the notorious North Korean hacking group Lazarus. The US Treasury Department asserted that Tornado Cash served as a vital instrument for this hacking group. During Pertsev’s trial in March, the prosecution contended that he failed to take sufficient measures to prevent criminals from utilizing Tornado Cash.

Yet, the defense contended that the prosecution had overlooked the fact that Tornado Cash functions on open-source and self-executing smart contracts. Pertsev emphasized that it was unjust to hold him accountable for the clandestine actions of Tornado Cash users, who actively choose anonymity and autonomy.

Several industry experts shared a similar perspective, including Raphaël Bloch, co-founder of “The Big Whale.” In a recent tweet, Bloch expressed concern over the verdict against Pertsev for money laundering, stressing that he merely created an open-source tool.

A Dutch court has ruled that Alexey Pertsev, a developer for Tornado.cash, is accountable for money laundering crimes. This judgment poses a significant risk as Pertsev merely created an open-source tool, equating his condemnation to punishing a knife or car manufacturer due to misuse by their users.

Additionally, Tornado.cash functions as a non-custodial cryptocurrency tumbler. This signifies that it neither keeps nor manages the funds transacted through the platform.

‘Sad Day For Privacy, Open-Source’

The result of this ongoing trial might establish a significant legal precedent for upcoming cases pertaining to other Tornado Cash developers indicted for money laundering and sanctions violation in the United States. Roman Storm and Roman Semenov, two additional developers implicated in these allegations, face similar charges.

Simultaneously, Storm’s trial is set for September, however, Semenov remains at large and hasn’t been taken into custody. Previously, Edward Snowden, a former NSA whistleblower, openly advocated for Storm’s cause in defense of his legal proceedings.

It was a lamentable day for privacy, cryptocurrency, and open-source communities, according to Pablo Sabbatella, the Head of Security Research at Blockfence.
