Roman Stormâs trial is almost over

Brought to you by:
In a semi-confusing turn of events, the Department of Justice says that it actually wonât be pursuing charges against Dragonfly.
The DOJ blamed reporting that came from inside the courtroom for the confusion, and Dragonflyâs Haseeb Qureshi said that the DOJ is simply not allowed to âspeculateâ on prosecuting a third party in an open court setting with media around.
Since our statement on Friday, we've received overwhelming support from across the crypto, tech, and venture communities. We want to sincerely thank you all for standing behind us.
The DOJ has now backtracked. They have stated on the record in the trial Monday morning that the

Speaking of courtâŚBen Strackâs back with an update on the Roman Storm trial this morning.
âď¸ Roman Stormâs defense rests
âNothing further from the defense,â attorney Brian Klein told Judge Katherine Polk Failla yesterday afternoon at Manhattanâs Thurgood Marshall courthouse.
The team representing Tornado Cash co-founder Roman Storm had cycled through what remained of its witness list, and Storm chose not to take the stand.
A reminder that Storm is being charged with conspiracy to commit money laundering, conspiracy to commit sanctions violations, and conspiracy to operate an unlicensed money transmitting business.
His defense (and advocates of the privacy protocol) argue Storm isnât criminally responsible for bad actors using something he helped create.
Closing arguments were scheduled to begin at 9 a.m. âsharpâ Wednesday â meaning in a matter of minutes (if youâre reading this when it publishes).
In the meantime, letâs go through Tuesdayâs witnesses and some of the more memorable moments:
Guy Wuollet, partner at a16z crypto
Tuesdayâs first witness, Wuollet had evaluated whether Andreessen Horowitzâs crypto/Web3 unit would invest in Tornado Cash in 2021.
In an email to Storm at the time, Wuollet wrote he was âimpressed by the strength of the privacyâ of Tornado Cash and âexcited about the next iteration of the protocol.â
The reason a16z didnât invest? Wuollet said the firm didnât know if Tornado Cash would be profitable.
âWe will continue to be fans of Tornado Cash and to track its adoption onchain,â Wuollet added in the email.
When asked to acknowledge that crimes are committed on the blockchain, Wuollet paused before saying he thinks of it differently.
âIf someone robbed a store, I wouldnât say the store was used in the crime.â
An attendee sitting to my left started laughing. The prosecution ended the cross-examination there.
Omid Malekan, Columbia Business School professor
Not on the stand long, Malekan said he used Tornado Cash in 2021 to purchase an Ethereum Name Service (ENS) name.
He used the protocol because he âdidnât want to put a bullseye on my back.â
The prosecutionâs Ben Arad shouted out an objection. Failla asked Klein to control his witness.
Dr. Stephanie Hurder, founding economist of Prysm Group
We found out the defense has so far paid Hurder $120,000 for her time analyzing this case and being an expert witness. She reviewed Tornado Cash DAO proposals, TORN token price data, transactions on Etherscan, etc.
She countered several points previously brought up by the government about Tornado Cashâs supposed lack of decentralization. Hurder noted the protocolâs DAO was âwell-designed and activeâ (55% of TORN tokens initially went to the DAO treasury) and that Tornado Cash founders did not have (or always use) their voting power on proposals.
She added that the founders did not have a direct hand in selecting entities on Tornado Cashâs relayer registry.
The governmentâs exchanges with Hurder were heated, with prosecutors getting her to acknowledge that bad actors have apparently used Tornado Cash to hide criminal proceeds. As we know, the case against Storm is more nuanced than that.
Dr. Matthew Green, computer science professor at Johns Hopkins University
Green, who helped create the Zerocash protocol, was brought in to emphasize the value of privacy.
Though he was intrigued with crypto and blockchain technology essentially from its outset, Green called the lack of privacy (i.e. public transactions) âa huge bug.â
He talked about the value of VPNs and credit-card tokenization in protecting individuals and institutions. At one point, I caught a juror dozing.
The Tornado Cash pools were immutable, Green confirmed â preventing hackers or founders from making changes there.
During the cross-examination, Arad asked Green whether the Tornado Cash website, user interface and relay registry could be changed. âYesâ to all three.
Also of note was Klein wanting Green to address the feasibility of a hypothetical user registry that one of the governmentâs witnesses, AnChain.AIâs Philip Werlau, brought up last week.
Greenâs initial hesitation to respond and a subsequent sidebar with the judge meant that the question went unanswered.
But as this case winds down and the jury is charged, weâll have other, more critical answers soon.
