Ethereum co-founder Vitalik Buterin has declared his solidarity with Virgil Griffith, the American citizen arrested for his blockchain educational activities in North Korea. In a tweet posted on Dec. 1, Vitalik shared a link to a blog post penned by blockchain firm CEO Enrico Talin, which had appealed directly to the Ethereum co-founder to start a petition in support of Griffith.

Griffith, a 36-year old U.S. citizen living in Singapore, was arrested at the Los Angeles International Airport on Nov. 29 and is set to be charged with conspiring to violate the International Emergency Economic Powers Act.

Griffith is alleged to have illegally traveled to the Democratic People's Republic of Korea to deliver a conference presentation - entitled "Blockchain and Peace" - on cryptocurrencies and blockchain. In declaring his support of Griffith, Buterin prefaced his arguments by disclosing a "Conflict-of-interest" insofar as Griffith is a friend of his. "Buterin further states that he does not believe Griffith gave the DPRK"any kind of real help in doing anything bad" - having only purportedly delivered a presentation based on already publicly accessible, open-source software.

Erin's arguments met a mixed response on Crypto Twitter, with some pointing to Griffiths' decision to travel to the DPRK despite allegedly having been denied permission to do so by the State Department.
