NEW YORK
Roman Storm, co-developer of Tornado Cash, confirmed that the Department of Justice is continuing its prosecution following a new filing in the Southern District of New York. The move comes as the Financial Crimes Enforcement Network simultaneously withdrew its proposed rule targeting cryptocurrency mixers—creating a split regulatory signal on privacy-enhancing protocols.
The SDNY filing signals the DOJ's unwavering commitment. Prosecutors allege Storm conspired to commit money laundering and sanctions violations, claiming Tornado Cash facilitated over $1 billion in illicit transactions. Storm's defense argues the protocol is neutral software and developers bear no liability for third-party misuse. The case will set precedent for how U.S. courts treat open-source developers.
FinCEN's decision to drop its proposed rule—unveiled in October 2023—suggests a tactical pause rather than a policy reversal. The rule sought to classify crypto mixers as "primary money laundering concerns" under the Patriot Act, imposing stringent reporting requirements on operators. The withdrawal removes an immediate compliance threat, but does not erase existing sanctions or the active enforcement action against Storm.
The contradiction matters: FinCEN retreats while the DOJ advances. This creates genuine uncertainty for developers and users. On-chain data shows cautious behavior—users increasingly resort to centralized exchange privacy features over decentralized mixers to sidestep legal exposure. The messaging to the crypto ecosystem is clear: regulatory arbitrage between agencies is real, and privacy tooling remains a minefield for developers regardless of macro sentiment.
Pre-trial motions and discovery phases will dominate the next phase. No trial date is set, but filings and hearings should accelerate over the coming months. The outcome will determine whether U.S. courts treat privacy protocols as neutral tools or as facilitators of crime—and whether developers can build them without personal legal jeopardy.
