A recent filing by Roman Storm’s defense team raises concerns about the US Department of Justice’s withholding of evidence in its case against the Tornado Cash developer, highlighting the importance of Brady obligations in crypto cases.
A recent filing by Roman Storm‘s defense team highlights concerns that the U.S. Department of Justice may have withheld evidence in its case against the Tornado Cash developer. The request, made to a federal judge overseeing the case, seeks an order for prosecutors to review their records and share relevant documents that could help Storm‘s defense.
The Case Against Samourai Wallet
In a separate case involving two developers of Samourai Wallet, defense attorneys had previously alleged that prosecutors had delayed sharing information about Financial Crimes Enforcement Network (FinCEN) officials’ views on the noncustodial nature of cryptocurrency mixers. The DOJ denied these allegations, stating that their disclosures were timely and not based on formal guidance.
Samourai Wallet is a mobile wallet designed for Bitcoin users, focusing on privacy and security.
It allows users to send and receive Bitcoin transactions without revealing their identity or transaction history.
The wallet uses Tor and Onion routing to encrypt transactions, making it difficult to track user activity.
Samourai Wallet also features a built-in Lightning Network node, enabling fast and low-cost transactions.
However, Roman Storm‘s team argues that this case is not ‘superficially similar‘ to its own case, but rather shares a core feature: the noncustodial nature of both protocols. This similarity raises questions about whether prosecutors in Storm‘s case are also withholding information that could impact his defense.
Brady Obligations and the Importance of Transparency

The Brady obligations refer to the duty of prosecutors to disclose exculpatory evidence to the defense, which can help ensure a fair trial. The recent filing by Roman Storm‘s team highlights concerns about the DOJ’s compliance with these obligations, particularly in light of its decision to drop a portion of its case against Storm.
A Brady obligation is a court order requiring the release of previously withheld evidence in a criminal case.
Named after the landmark case Brady v. Maryland (1963), it ensures that defendants have access to exculpatory information, potentially affecting their guilt or sentence.
This right is guaranteed by the US Constitution's Sixth Amendment and is enforced through federal and state laws.
Failure to disclose such evidence can lead to appeals, reversals, or even retrials.
By requesting an order for prosecutors to review their records and share relevant documents, Storm‘s defense team aims to uncover any information that could help his case. This request underscores the importance of transparency and accountability in the prosecution of cryptocurrency-related cases.
Next Steps and Implications
The outcome of this request remains uncertain, but it highlights the need for greater scrutiny of Brady obligations in crypto cases. As prosecutors continue to navigate complex regulatory landscapes, the importance of transparent communication with defense attorneys cannot be overstated.
Ultimately, the case of Roman Storm serves as a reminder of the critical role that transparency and accountability play in ensuring fair trials and upholding justice.
