International cooperation in law enforcement will become a major trend in combating cryptocurrency crimes

With the advent of globalization and digitalization, the rapid development of the cryptocurrency market has brought new business opportunities, but also posed new challenges to laws and regulations around the world. The increasing interaction between cryptocurrencies and legal currencies has led to an increase in illegal activities such as money laundering and terrorist financing. At the same time, due to the fact that blockchain technology is not the professional field of law enforcement departments, it is difficult to locate specific criminals, and law enforcement departments face greater challenges in combating these illegal activities. In addition, from multiple incidents, the regulation of cryptocurrencies requires not only the support of local laws, but also international cooperation to deal with cross-border crimes, money laundering, terrorist financing and other issues. Therefore, international cooperation in law enforcement and the use of blockchain data analysis technology will become a major trend in combating cryptocurrency crimes.

Cryptocurrency and Criminal Activities

According to CoinMarketCap data, the global market value of cryptocurrencies has exceeded 2 trillion US dollars. Cryptocurrencies have become more and more popular, and their decentralization, anonymity and cross-border circulation capabilities have brought many conveniences to users. However, these characteristics also make cryptocurrencies a tool for money laundering, terrorist financing and other illegal activities.

According to the SlowMist Blockchain Hack Archive (https://hacked.slowmist.io/), blockchain crimes have caused at least $33.4 billion in losses since 2012:

Cryptocurrency can be used for both payment and investment, and has strong anonymity, which has also led to a gradual increase in demand for cryptocurrency by transnational organized crime groups (such as ransomware and terrorism). Simply put, cryptocurrency has greatly reduced the operating costs of transnational organized crime. They not only use cryptocurrency arbitrage to obtain more funds, but also can transfer huge amounts of money without arousing suspicion. For example, in order to circumvent regulatory measures implemented within the international banking system, some criminal organizations raise cryptocurrency through online platforms that support anonymous donations. Previously, Interpol also disclosed information that organized crime groups used cryptocurrency for large-scale money laundering. These cases all show that the characteristics of cryptocurrency such as "virtual", "anonymous", "difficult to trace" and "cross-border" make it difficult for a single country or region to effectively regulate it, bringing new challenges to law enforcement.

International cooperation in law enforcement to combat cryptocurrency crimes

To cope with the law enforcement challenges brought by cryptocurrency, we believe that we need to rely on international cooperation to achieve effective supervision and law enforcement. Law enforcement agencies of various countries need to act together to respond to the ever-changing means and techniques of cryptocurrency crimes and achieve precise crackdowns on criminal behavior. Several successful cases of international cooperation in law enforcement in the field of cryptocurrency have demonstrated the necessity and effectiveness of this trend:

• On August 20, 2024, with the cooperation of China and Thailand, the "Fox Hunting Operation" working group of the Ministry of Public Security of China successfully extradited economic crime suspect Zhang Moumou from Thailand. Zhang Moumou is suspected of organizing and leading pyramid schemes. This case is the first economic crime suspect extradited from Thailand by China, marking a major progress in China-Thailand law enforcement and judicial cooperation. The group involved in Zhang Moumou carried out online pyramid selling activities by issuing virtual digital currency, involving more than 100 billion yuan and more than 10 million members.

• In May 2024, with the support of Eurojust and Europol, the French police arrested a suspect in conjunction with Portugal, Germany, Italy and Romania. The suspect used a fraudulent method that caused a loss of 700,000 euros to Portuguese victims. The suspect approached the victims by expressing interest in acquiring commercial enterprises, and after winning the victims' trust and persuading them to install a crypto asset wallet, he stole the victims' funds.

• On February 19, 2024, the notorious extortion gang LockBit's website was seized in a joint law enforcement operation by the UK National Crime Agency, the US Federal Bureau of Investigation, Europol and the International Alliance of Police Agencies.

• In 2022, the law enforcement operation codenamed "HAECHI III" seized a total of $130 million in illegal cryptocurrency proceeds. A total of police units from 30 countries and regions joined in the cooperation and arrested nearly 1,000 cybercriminals. Interpol also blocked nearly 2,800 bank and crypto asset accounts used for crimes, including pig-killing, investment fraud, online gambling and transnational money laundering.

• DarkMarket is one of the world's largest dark web markets, mainly conducting illegal transactions through Bitcoin and Monero. In January 2021, the German police, together with law enforcement agencies from 15 countries including the United States, the United Kingdom, Denmark and Switzerland, successfully closed DarkMarket, arrested the main suspect, and froze millions of dollars in virtual assets.

The above cases all demonstrate the importance of international cooperation and targeted technical support. Regardless of where the illegal profits are made, international cooperation to recover assets and combat crime effectively reduces the risk of using cryptocurrencies for illegal activities.

The role of blockchain technology in combating cryptocurrency crime

In addition to international cooperation, making full use of blockchain technology is also very important in combating cryptocurrency crime. Blockchain itself is a highly transparent and traceable distributed ledger, which means that advanced analytical tools and machine learning algorithms can be used to track transaction activities in real time and identify abnormal transaction patterns, thereby effectively combating money laundering and other illegal transactions.

For example, professional blockchain companies can prevent, identify and track cryptocurrency-related money laundering crimes by analyzing the large amounts of data they have, using technology as an important aid in preventing cryptocurrency crimes and investigations. In addition, although the transaction data on the chain is open and transparent, its anonymity and decentralization make it very difficult to directly link on-chain behavior to specific individuals. This requires law enforcement agencies to have the corresponding technical knowledge to effectively identify and collect evidence and seize illegal gains, which is inseparable from professional on-chain tracking and investigation training. In this context, blockchain security and compliance solutions such as SlowMist AML (https://aml.slowmist.com) play a vital role in helping to discover and analyze on-chain risks and prevent cryptocurrency-related crimes.

Written in the end

With the continuous development of the global digital economy, cryptocurrency plays an increasingly important role in the financial system, and related regulatory issues are becoming more and more complex. We can foresee that international cooperation will become more frequent and in-depth in the field of cryptocurrency, covering all aspects of cryptocurrency regulation and law enforcement. We believe that through this collaboration, the world will be better able to cope with the new challenges brought by cryptocurrencies, help combat illegal activities and maintain market order, and ensure the security and stability of the financial system. SlowMist will also continue to work hard to build a safer blockchain ecosystem.
