In a recent report, the European Union Agency for Law Enforcement Cooperation (Europol) expressed serious concerns about the potential misuse of crypto mining and layer 2 blockchain solutions by criminal elements. The agency warns that these technologies could pose significant challenges to law enforcement investigations, potentially hindering their ability to trace illicit funds and recover stolen assets.
Crypto Mining: a lucrative laundering system?
The Europol report highlights the growing trend of criminals using crypto mining operations to obscure the origins of their ill-gotten gains. By integrating illicit proceeds into mining activities, criminals can effectively launder their money and even generate additional profits at the same time.
The agency has detected suspicious activity in mining pools, particularly those operated by ransomware operators, who use these platforms to promote their criminal enterprises.
“Pool mining schemes have also been used by scammers to run their Ponzi schemes,” the report said. “For example, the BitClub network promised revenue from pool mining, even though these pools did not actually exist; defrauded investors lost hundreds of millions of euros.
Layer 2 Solutions: A Double-Edged Sword
While layer 2 blockchain solutions have been touted as a way to improve scalability and reduce transaction costs, Europol views them as a potential threat to law enforcement efforts. The agency warns that the growing use of zero-knowledge proofs and other layer 2 applications could make it much more difficult to track the flow of funds on the blockchain.
These technologies could pose additional challenges for law enforcement investigations,” the report said, without specifying the specific challenges these solutions could introduce.
Europol report: the SLIP39 enigma
Europol also highlights the potential complications posed by the SLIP39 standard, commonly known as Shamir Backup, which is used by many hardware crypto wallets. This standard allows the creation of multiple recovery shares instead of a single mnemonic phrase, with each share consisting of 20 words.
A user-defined number of these shares is required to restore a wallet, which adds an additional layer of complexity for law enforcement agencies seeking to recover a criminal's assets. “The task of recovering a criminal's wallet could be significantly complicated due to SLIP39,” the report said.
Is cryptocurrency mining criminal in nature?
Although Europol's concerns are well-founded, it is important to note that cryptocurrency mining and layer 2 solutions are not criminal in nature in themselves. These technologies have many legitimate applications and have the potential to revolutionize the financial industry. However, as with any powerful tool, there is always a risk of misuse by bad actors.
To address these challenges, Europol calls for increased collaboration between law enforcement, regulators and the crypto industry. By working together to develop robust anti-money laundering (AML) and counter-terrorism financing (CTF) measures, while driving innovation in the crypto space, it may be possible to strike a balance between security and progress.
The report was produced by the following members of the EU Internal Security Innovation Hub: Europol, Eurojust, European Commission Directorate-General for Migration and Home Affairs (DG HOME), Joint Research Center (JRC) of the European Commission, the counter-terrorism coordinator of the European Council, and the European Union Agency for the operational management of large-scale IT systems in the area of freedom, security and justice (EU-LISA).
