How does the Bitcoin Fog ruling affect Roman

Published 10/7/2026, 12:30:49 PM

Answer

The Bitcoin Fog ruling is being used by federal prosecutors as a direct precedent to defeat Roman Storm's venue challenge in the Southern District of New York (SDNY). The D.C. Circuit's September 2026 affirmance of Roman Sterlingov's conviction gives the DOJ appellate authority for the exact venue theory it needs in Storm's case, though the analogy to a non-custodial protocol remains contested.

1. What the Bitcoin Fog ruling held (the precedent)

On September 25, 2026, the U.S. Court of Appeals for the D.C. Circuit affirmed the conviction and 150-month sentence of Bitcoin Fog operator Roman Sterlingov in USA v. Sterlingov, No. 24-3161 [Source: https://www.armstrongdc.com/white-collar-crypto-fraud-defense-blog/sterlingov-bitcoin-fog-appeal-chainalysis-reactor; https://law.justia.com/cases/federal/appellate-courts/cadc/24-3161/24-3161-2026-09-25.html]. The court held that venue in Washington, D.C. was proper for all four counts [Source: https://cointelegraph.com/news/roman-storm-bitcoin-fog-doj-acquittal-bid]:

2. How the DOJ applies it to Storm

In a Monday (Oct. 5, 2026) filing in U.S. v. Storm (1:23-cr-00430, SDNY) [Verified: Court records confirm the case is docketed as United States v. Storm, 1:23-cr-00430, in the Southern District of New York, before Judge Katherine Polk Failla (KPF). See CourtListener docket: https://www.courtlistener.com/docket/67720380/united-states-v-storm/; DOJ SDNY press release: https://www.justice.gov/usao-sdny/pr/tornado-cash-founders-charged-money-laundering-and-sanctions-violations; case filings confirm "Case No.: 23 Cr. 430 (KPF)": https://storage.courtlistener.com/recap/gov.uscourts.nysd.604939/gov.uscourts.nysd.604939.214.0.pdf], prosecutors told Judge Katherine Polk Failla that the Bitcoin Fog ruling "directly supports" their position [Source: https://www.cryptobreaking.com/doj-cites-bitcoin-fog-ruling/]. Their argument: just as a single undercover agent's transactions from a D.C. office established venue in Bitcoin Fog, a single Tornado Cash user's transactions from his Manhattan apartment are enough to establish New York venue for Storm's money-laundering and unlicensed money-transmission charges [Source: https://www.tftc.io/doj-bitcoin-fog-ruling-roman-storm-acquittal-bid; https://decrypt.co/380260/prosecutors-cite-bitcoin-fog-ruling-against-roman-storms-venue-challenge].

3. Where the case stands

  • Storm was convicted (partial verdict) of conspiracy to operate an unlicensed money-transmitting business.
  • His defense moved for acquittal (April 2026) and separately moved to dismiss for lack of venue, arguing the government has not sufficiently established venue.
  • Judge Failla has not yet ruled on the acquittal motion.
  • A retrial on the money-laundering and sanctions charges is scheduled for April 26, 2027, pending the outcome [Source: https://tradersunion.com/news/cryptocurrency-news/show/3693818-doj-bitcoin-fog-roman-storm-acquittal].

4. The counterpoint / context

Storm's team has contrasted the DOJ's aggressive venue filing with the fact that the U.S. Treasury/FinCEN withdrew its proposed crypto-mixer reporting rule around the same time [Source: https://thedefiant.io/news/regulation/doj-presses-roman-storm-case-as-fincen-drops-mixer-proposal; https://cryptoslate.com/doj-presses-tornado-cash-prosecution-as-treasury-drops-mixer-reporting-plan]. The defense framing is that the executive branch is simultaneously backing away from regulating mixers while the DOJ criminalizes them. This is a policy-tension argument, not a legal rebuttal to the venue precedent itself.

Assessment

The Bitcoin Fog ruling is a meaningful headwind for Storm's venue challenge because it supplies appellate authority for the exact theory the DOJ needs: that a single in-district user transaction can establish venue for money-laundering counts, and that serving customers in the district establishes venue for unlicensed money-transmission counts. However, the analogy is not perfect — Bitcoin Fog was a centralized, operator-controlled service, whereas Storm's defense rests on Tornado Cash being permissionless, immutable software he did not control once deployed [Source: https://blockworks.com/news/storm-seeks-acquittal]. Whether the D.C. Circuit's reasoning transfers cleanly to a non-custodial, open-source protocol is the crux the court has yet to resolve. The venue ruling is pending, and the retrial is set for April 26, 2027.
