DOJ invokes Bitcoin Fog ruling in potential blow to Roman Storm acquittal bid
Prosecutors say a recent Bitcoin Fog appeals court ruling supports their argument that Tornado Cash activity in Manhattan was enough to establish venue for parts of Roman Storm’s case in New York.
Asanat Analysis — Why it matters
The DOJ's invocation of Bitcoin Fog precedent signals prosecutors are building a multi-jurisdictional enforcement strategy against privacy-mixing services. Bitcoin Fog, a predecessor to Tornado Cash, established that mixing activity itself—independent of underlying crime—can create legal venue in any jurisdiction where funds transited. If applied to Storm's case, this precedent weakens arguments that Tornado Cash operations in Manhattan lack sufficient nexus to New York courts, potentially keeping the case in a jurisdiction where prosecutors perceive tactical advantages.
This development reflects a broader shift in how courts treat anonymity infrastructure. Regulators are no longer required to prove specific criminal use of mixed coins; rather, the mixing itself is treated as a jurisdictional anchor point. For the privacy-tech sector, this suggests venue-shopping risk is now endemic to mixing protocol liability—operators face exposure across multiple districts simultaneously, complicating defense strategies that rely on geographic limitations to enforcement.
