Why Are These Sanctions Significant?

One point that has been consistently emphasized by experts and lawyers in the regulatory space is the caution needed when dealing with the Office of Foreign Asset Control (OFAC), which operates under the U.S. Department of the Treasury. Many believe that while crypto investors can challenge the Securities and Exchange Commission (SEC) and sometimes win, this is unlikely when it comes to OFAC. The office is known for its rigorous actions.

In March, Roman Semenov, one of the developers behind Tornado Cash, spoke to Bloomberg and stated that it would be nearly impossible to sanction decentralized protocols. He specifically referenced his privacy mixer as an example of such smart contracts.

However, all of this came to a sudden halt earlier this week when OFAC imposed sanctions on Tornado Cash. What has puzzled many is the speed at which the repercussions unfolded. For instance, Circle immediately froze around $70,000 worth of USDC on Tornado Cash, while dYdX, the crypto exchange, swiftly blocked all accounts that had interacted or transacted with Tornado. GitHub also took action, suspending the official Tornado account, as well as Semenov’s account.

Now, the question remains: what exactly does it mean to engage with a sanctioned address? A curious development occurred when an unknown user sent small amounts of ETH to several celebrities using Tornado. This may have been an attempt to show that sanctions on protocols like Tornado are not always effective.

The North Korea Connection

Among the most pressing concerns is the involvement of North Korea. When announcing the sanctions, the U.S. Treasury Department revealed that Tornado Cash had been used to launder over $455 million, which coincidentally matches the amount stolen by the Lazarus Group, a hacking collective sponsored by the Democratic People’s Republic of Korea. The U.S. imposed sanctions on this group in 2019, and this heist is now recognized as the largest crypto theft in history.

In addition, Anne Neuberger, the Deputy National Security Adviser, voiced concerns about North Korea’s cyber capabilities during a public address. This follows a UN report revealing that North Korea has used more than $50 million in stolen crypto assets to fund its nuclear weapons program. Essentially, the Treasury Department is indicating that North Korea has not only stolen crypto but has used it to finance its weapons development. Furthermore, it appears that Tornado Cash played a role in helping transmit these funds in a way that avoided public detection.

The Technology Perspective

Another angle to consider is the technology behind Tornado Cash. It is an open-source protocol built on a decentralized framework. Unlike Blender.io, which was also sanctioned by OFAC, Tornado Cash does not operate as a centralized business that could be shut down. Instead, it functions through a governance token, with holders voting on whether to accept or reject any proposed changes or forks. Non-U.S. holders are not bound by U.S. sanctions, allowing them to continue operations as they see fit.

The open-source nature of Tornado Cash has complicated the situation. An unknown user has continued to send small amounts of ETH via Tornado, even after the sanctions were imposed. Notable figures such as Dave Chappelle and Jimmy Fallon have reportedly received these amounts.

Finally, there is the privacy issue. Many users of Tornado Cash were motivated by the desire for privacy. According to statistics from the Treasury Department, Tornado Cash has processed over $7 billion in cryptocurrency over the past three years. While experts estimate that about 20% of these transactions were illicit, this still leaves $5 billion transacted by individuals seeking privacy. Many in the crypto community view the sanctions as an attack on privacy rights.

Groups such as Fight for the Future, Coin Center (a crypto think tank), and Ethereum co-founder Vitalik Buterin have openly opposed the sanctions. As the situation develops, Tornado Cash’s response will be crucial in determining the next steps. If the transaction volume continues to rise, the Treasury may impose further sanctions.
