Ethereum co-founder Vitalik Buterin has publicly intervened ahead of the sentencing of Tornado Cash developer Roman Storm, warning that prosecutors are punishing software creation rather than demonstrable financial harm.
The appeal was published Friday, January 9, 2026, as Storm awaits a decision that could carry prison time.
Privacy Tools Framed as Legitimate Infrastructure
In his letter, Buterin described privacy-preserving software as a necessary response to pervasive data exploitation, cybercrime, and surveillance. He said he has personally used tools like Tornado Cash for lawful purposes, including purchasing technical tools and supporting human rights charities, without creating permanent records across corporate or government databases.

The point, he wrote, is not secrecy for wrongdoing, but basic transactional privacy.
Code as Speech and Developer Liability
Buterin aligned with the core legal argument in Storm’s defense: publishing open-source code constitutes protected speech under the First Amendment. He argued the case risks redefining software development as a criminal act when third parties misuse code, an approach that, in his view, targets authorship rather than intent or direct harm.
Praise for Storm’s Conduct
The letter also addressed Storm’s character and work. Buterin called him a principled developer whose applications continued to function long after active development stopped, an outcome he described as “more honorable than much of what passes for ‘consumer tech’ in our modern world.” The emphasis was on durability and integrity, not growth or monetization.
Financial Backing for the Defense
Support has extended beyond statements. Buterin confirmed personal donations to Storm’s legal defense fund, alongside significant contributions from the Ethereum Foundation. The fund raised more than $6.3 million in 2025 alone, underscoring the case’s resonance within the developer community.
Case Background and Stakes
Storm was convicted in August 2025 on a money-transmitting conspiracy charge, carrying a potential sentence of up to five years. U.S. authorities alleged Tornado Cash facilitated laundering of more than $1 billion in illicit funds, including proceeds linked to North Korean hackers. Storm remains free on bail pending sentencing.
The case has broader implications. Tornado Cash co-founder Alexey Pertsev received a 64-month sentence in a separate Dutch proceeding and was later released under electronic monitoring while appealing. For many developers, Storm’s sentencing is now a defining test of where responsibility for open-source code begins, and ends.
