  • “No one should define him by this mistake,” Brian Klein, an attorney for Griffith, said
  • As part of his plea deal, Griffith will likely face up to 6 years in prison

Virgil Griffith, a prominent Ethereum developer, pleaded guilty to a conspiracy charge at the beginning of the landmark trial in the Southern District of New York on Monday. 

Griffith is being accused of conspiracy to violate sanctions laws. The federal charge against him surrounds a trip to North Korea in 2019, where he gave a presentation on blockchain technology and cryptocurrency at a conference in Pyongyang. 

According to the Department of Justice, Griffith was conspiring to violate the International Emergency Economic Powers Act (IEEPA) during the trip. IEEPA prohibits US citizens from exporting services such as intellectual property and technology to North Korea without a license from the Department of Treasury. 

The case revolves around Griffith’s intent and not the consequences of his actions; as noted by journalist Ethan Lou — who says he was with Griffith when he gave the presentation in 2019 — the 38-year-old developer stands accused of “trying to help North Korea, not actually helping.”

Monday’s plea could also signal the tail end of a two-year-long legal battle between attorneys for Griffith and the prosecution.

According to a court filing, Griffith had allegedly first sought approval to go to the conference in Pyongyang, but was denied. He was arrested several months later at Los Angeles International Airport while travelling on Thanksgiving, per a release from the US Attorney’s Office for the Southern District of New York. 

In a written statement on Monday, US Attorney Audrey Strauss said that Griffith “agreed to help one of [the] nation’s most dangerous foreign adversaries.”

“Griffith jeopardized the national security of the United States by undermining the sanctions that both Congress and the President have enacted to place maximum pressure on the threat posed by North Korea’s treacherous regime,” Strauss said. 

Previously, Griffith’s lawyers retorted that the information in the presentation at the Pyongyang blockchain conference was public and readily accessible online.

Some prominent voices in the Ethereum community agree. Following Griffith’s arrest in 2019, Vitalik Buterin tweeted:

Brian Klein, a lawyer for the defendant, said in a statement that his client “is sincerely remorseful” and has “many wonderful qualities.”

“Setting aside what happened, he has made important contributions to society that we will raise with the court,” Klein added. “No one should define him by this mistake.”

Klein requested on Monday that Griffith be removed from Metropolitan Correctional Center and transferred to a different facility, such as Essex County Correctional Facility in New Jersey. He described the current conditions of MCC as being “very, very difficult” for his client, a court transcript revealed. 

US District Judge Kevin Castel asked Griffith how he felt both “physically” and “mentally” in court on Monday. 

“I have a lot of complex feelings throughout my body,” the defendant responded. “I’ve been doing meditation training and I have much greater acuity of how awful I feel.”

As part of his plea agreement, Griffith could face 63 to 78 months (or more) in prison, the judge said. Formal sentencing is scheduled to begin in January of next year.

Fully homomorphic encryption is emerging as the leading cryptographic approach to onchain confidentiality, enabling computation directly on encrypted data without exposure. We are constructive on FHE as a category and Zama as the clear leader, though the 1,000x+ computational overhead and hardware dependency represent material execution risks that make throughput scaling the key variable for valuation.
