The Financial Crimes Enforcement Network (FinCEN), a bureau of the U.S. Department of the Treasury, recently announced proposed rules aimed at enhancing scrutiny over cryptocurrency mixing platforms. According to the agency, such services are leveraged by terror groups and rogue nations to obscure their financial activities. The institution refers to these platforms as “Convertible Virtual Currency Mixing” or CVC mixing services.

In the most recent policy update, FinCEN aims to require financial organizations to disclose transactions linked to international CVC mixing platforms, which it identifies as posing a “critical risk to both money laundering and national security.” Prominent Bitcoin (BTC) and Ethereum (ETH) mixing services that utilize Coinjoin technology allow users to amalgamate their transactions, thus disguising the origins and final destinations of their funds.

Andrea Gacki, FinCEN’s director, noted that cryptocurrency mixing platforms facilitate the “financial mechanisms for ransomware attacks, rogue nations, and other criminal enterprises to underwrite their illegal activities.” Deputy Treasury Secretary Wally Adeyemo reiterated the department’s commitment to inhibiting the use of crypto mixers by terrorist organizations, cybercriminals, and sanction evaders.

After previously categorizing various cryptocurrency mixing services like Tornado Cash and, the Treasury Department proceeded to propose new regulations. These platforms are accused of facilitating the laundering of millions of dollars originating from hacks associated with countries such as North Korea.

The agency disclosed that Tornado Cash was implicated in “obscuring the transfer of over $455 million pilfered in March 2022 by the OFAC-listed, North Korea-affiliated Lazarus Group in the most substantial virtual currency theft recorded to date.”

However, privacy proponents argue that regulatory actions against mixers adversely impact regular users who rely on them. Coin Center, a nonprofit organization focused on cryptocurrency policy, lodged a formal objection against the Treasury Department’s ban on Tornado Cash in October 2022, asserting that it exceeds the Treasury’s legal authority.

Coinjoin technologies mask user identities by pooling funds from diverse sources. While such activities can sustain privacy without malevolent purposes, FinCEN maintains that these tools are abused by malicious actors.

In addition to Tornado Cash and, the Office of Foreign Assets Control (OFAC) has identified several cryptocurrency addresses linked to alleged malefactors. There is speculation that upcoming proof-of-stake (PoS) validators and proof-of-work (PoW) miners may have the capacity to block transactions from sanctioned entities and individuals.

In the Ethereum network, there has been a growing caution toward OFAC-compliant blocks over the last two years, with approximately 30% of Ethereum blocks currently adhering to OFAC guidelines. Moreover, in early May 2021, the Bitcoin mining company Marathon generated the inaugural OFAC-compliant block, although the company later discontinued this approach.

The latest action by FinCEN is in line with a legislative initiative led by Sen. Elizabeth Warren (D-MA), which has garnered the support of 100 additional lawmakers. They have urged the Biden administration to address the mounting concerns related to “cryptocurrency-related illicit financial risks.”

Seriously concerned about privacy here. What about people who use mixers for legit reasons? Seems like we’re moving toward big-brother levels of scrutiny.

PolicyWatcher October 21, 2023 - 10:02 am

Elizabeth Warren and 100 other lawmakers are behind this? That’s a strong political force. Seems like crypto regulation is getting more bipartisan support.

JohnDoe October 21, 2023 - 3:21 pm

Wow, FinCEN’s really crackin down huh? Mixing services have been around for a while and now they’re being targetted. Not sure how I feel about it, but guess something’s gotta be done about money laundering.

Stricter regulations might actually be good for institutional investors. Makes the whole ecosystem look less like the wild west and more like a mature market.

JustCurious October 21, 2023 - 6:40 pm

what’s the deal with these OFAC-compliant blocks? Are they like, blocks that play nice with the government or something? Seems like more of these might pop up with these new regs.

FinanceGuru October 21, 2023 - 8:31 pm

FinCEN stepping up regulations was long overdue. With crypto becoming mainstream, it’s natural that regulators wanna minimize risks. But the challenge is finding a balance, and that’s the tricky part.

TechNerd October 21, 2023 - 9:48 pm

Kinda surprised that Marathon dropped their OFAC-compliant block. Wonder what led them to do that? The crypto space is so volatile, always changing.

AnonymousUser October 21, 2023 - 11:26 pm
