As the weekend neared, jurors in a high-profile federal case involving alleged exploitation of Ethereum’s blockchain through MEV (Maximal Extractable Value) bots appeared no closer to reaching a consensus. After nearly three full days of deliberations, the jury tasked with determining the guilt or innocence of brothers Anton and James Peraire-Bueno remained deadlocked, prompting concerns that the trial could extend far beyond typical timelines for similar cases.
The case centers around a $25 million exploit that prosecutors claim was orchestrated by the brothers using MEV bots — automated programs that capitalize on inefficiencies or opportunities within blockchain transactions. According to prosecutors, the Peraire-Bueno brothers manipulated the Ethereum network by posing as legitimate validators, thereby gaining access to and extracting substantial crypto assets through deceptive means.
On Friday, jurors submitted a request for further clarification from the judge regarding the brothers’ intentions, signaling ongoing confusion or disagreement over the interpretation of their actions. Despite receiving additional guidance from Judge Jessica Clarke, the panel reported continued difficulty in arriving at a unanimous decision. The judge, however, denied a motion from the defense attorneys to declare a mistrial and instead instructed jurors to order dinner and resume deliberations into the evening.
While the court had not issued an Allen charge — a legal instruction given to encourage consensus among a divided jury — Judge Clarke retained the option to do so if signs of a complete impasse emerged. The absence of such a directive suggests the court still holds out hope for a resolution without resorting to more extreme procedural measures.
Interestingly, the length of these deliberations starkly contrasts with previous crypto-related cases. For instance, the jury in the criminal trial of former FTX CEO Sam Bankman-Fried reached a verdict in just five hours, despite the case involving seven felony counts. The drawn-out nature of the Peraire-Bueno trial may indicate the jurors’ struggle with the technical complexity of MEV bots and whether their use constitutes criminal behavior under existing laws.
The defense has argued that the brothers’ actions did not amount to fraud, asserting that they operated within the rules of the Ethereum network and merely exploited publicly available data — a practice not uncommon among blockchain participants. They contend that no deception occurred, and therefore no crime was committed.
In contrast, the prosecution has pushed the narrative that the brothers engineered a sophisticated scheme to unlawfully siphon funds by misrepresenting their role in the blockchain ecosystem. Central to their argument is the notion that the defendants intentionally misled other participants to gain an unfair advantage, which ultimately resulted in the unauthorized transfer of digital assets.
Whether jurors view the brothers’ conduct as savvy blockchain maneuvering or illegal activity remains the crux of the case. The legal system’s struggle to define the boundaries of permissible behavior in decentralized ecosystems is increasingly evident as such disputes reach federal courts.
As of late Friday, it was unclear whether a verdict would be reached before the weekend. Jurors had indicated a willingness to continue deliberating until at least 7:30 p.m. Eastern Time, but progress remained elusive. The extended timeline raises questions about the jury’s ability to reach consensus at all, and whether a mistrial could eventually be declared if the impasse persists.
The case has drawn significant attention from the blockchain and legal communities alike, as it could establish a precedent for how MEV-related activities are interpreted under U.S. law. The court’s ruling may have broader implications, potentially influencing future regulations and enforcement actions related to blockchain operations.
Beyond the immediate legal implications, the trial has also highlighted the growing tension between innovation in decentralized finance and the traditional legal frameworks attempting to govern them. MEV strategies — though controversial — are not inherently illegal, and the lack of regulatory clarity has left room for interpretation. This ambiguity places both developers and investors at risk, as actions once considered innovative could be retroactively deemed fraudulent.
Legal experts have noted that this case may serve as a litmus test for how courts handle increasingly complex blockchain-based schemes. The outcome could spur calls for clearer legislation or regulatory guidelines to define acceptable behavior in decentralized systems, particularly around transaction ordering and validator conduct.
From a technical perspective, MEV bots operate by scanning the blockchain’s pending transaction pool (the mempool) and executing trades that capitalize on price discrepancies or other exploitable patterns. While technically sophisticated, these practices often tread a fine line between competitive advantage and manipulation. The Peraire-Bueno case brings that line into sharp focus, challenging jurors to make sense of technical intricacies within a legal framework not designed for such cases.
Another layer of complexity involves the decentralized nature of Ethereum itself. With no central authority governing the blockchain, questions arise around jurisdiction, enforcement, and accountability. If the brothers are found guilty, it could establish that even in decentralized systems, actors may still be held liable under traditional fraud and conspiracy laws.
Regardless of the verdict, the trial underscores the urgent need for crypto-native legal expertise in the courtroom. As blockchain technology continues to evolve, so too must the legal system’s ability to interpret and adjudicate these matters fairly and effectively.
In the coming days, if the jury remains deadlocked, Judge Clarke may be forced to take more definitive action — including potentially declaring a mistrial. Until then, deliberations continue, and the blockchain world watches closely, aware that the outcome could shape the future of decentralized finance legality in the United States.
