The technological support for blockchain money laundering mainly stems from its core characteristics, such as anonymity, immutability, and decentralization. These features enable criminals to conduct complex fund transfers through blockchain, concealing the sources of illegal funds. Governments and regulatory bodies around the world combat blockchain money laundering because it poses a threat to global financial security and economic order and may be used to finance crime or terrorism.
Technological Support for Blockchain Money Laundering
Anonymity and Privacy
Although all transaction records on the blockchain are public, the identities of the transaction parties are not directly displayed. For example, the Bitcoin network uses wallet addresses for transactions, and these addresses are not directly linked to specific individuals. This pseudonymity provides a certain cover for money launderers, allowing them to hide the sources of funds through multiple wallet addresses and complex transaction networks.
Privacy Coins: In addition to conventional cryptocurrencies like Bitcoin, some privacy coins (such as Monero and Zcash) offer higher levels of anonymity, making transactions untraceable. The privacy features of these currencies attract participants in some money laundering activities.
Decentralization and Borderlessness
Blockchain networks are decentralized, meaning there is no central authority controlling them, and all transaction records are distributed across nodes worldwide. This allows cryptocurrencies to easily bypass traditional banking systems, enabling cross-border transfers through a peer-to-peer network without the oversight or restrictions of traditional financial systems.
Cross-Border Money Laundering: Since cryptocurrencies have no borders, money launderers can easily transfer funds from one country to another, operating through different exchanges or DeFi (Decentralized Finance) platforms to evade monitoring by banks and governments.
Mixing Services
Mixing services (or "tumblers") are tools designed to enhance transaction anonymity. They mix cryptocurrencies from different users together and then disperse them back to users, obscuring the trails of fund flows. These services make it more difficult to trace the sources of funds.
Example: Mixing services like Tornado Cash are widely used in some high-anonymity blockchain projects, allowing users to disperse transfers and conceal the original sources of transactions.
Decentralized Finance (DeFi) Platforms
DeFi platforms typically do not require strict KYC (Know Your Customer) processes, allowing users to operate through lending, trading, staking, and other methods without providing any identity information. This creates an unregulated financial environment for money launderers.
No KYC Transactions: Since many DeFi platforms do not mandate identity verification, money launderers can utilize these platforms to move funds globally without exposing their true identities.
Smart Contracts and NFTs
Smart Contracts: Smart contracts allow for the automatic execution of transactions on the blockchain. Although they are designed to streamline transaction processes and enhance trust, they can also be used to obscure complex money laundering schemes. Criminals can write contracts to automatically transfer or disperse funds.
NFT (Non-Fungible Token) Market: Some criminals may exploit false transactions to purchase high-value NFTs, artificially inflating their value to "clean" illegal gains.
Reasons for Countries to Combat Blockchain Money Laundering
Security of the Financial System
Money laundering activities pose a severe threat to the stability of the global financial system. If money laundering is not effectively controlled, criminal organizations and terrorists will leverage these illegal funds to further expand their influence, potentially triggering financial crises. The emergence of blockchain technology has created a new "breeding ground" for money laundering, prompting countries to strengthen their regulations.
Financing Terrorism: The anonymity of blockchain technology enables terrorist organizations to raise funds through cryptocurrencies for financing terror activities. Combating these activities is crucial for global security.
Drug Trafficking and Human Trafficking: Criminals engage in drug trafficking, human trafficking, and other illicit activities using cryptocurrencies, with money laundering helping these organizations legitimize their illegal gains and fuel the expansion of crime.
Tax Evasion and Economic Crimes
Fund transfers conducted through blockchain may circumvent national tax systems, resulting in a loss of government revenue. Criminals hide assets through cryptocurrencies, evading tax regulations and impacting national financial income.
Tax Money Laundering: Money launderers may conceal illegal funds in cryptocurrency accounts to avoid declaration and payment of taxes, constituting economic crimes.
Increased Risk of Financial Crime
Blockchain money laundering could lead to a sharp increase in financial crimes, as cryptocurrencies make it easier for criminals to transfer funds into hard-to-trace channels. This poses a significant challenge to the global financial system, especially in the context of cross-border transactions and globalization.
Criminal Activities Outside the Traditional Financial System: Blockchain provides an environment free from bank and government oversight, allowing criminals to easily utilize it to transfer and hide funds, increasing the difficulty of combating financial crime globally.
Public Trust and Market Confidence
The legitimate applications of blockchain and cryptocurrencies (such as payments, asset management, and decentralized applications) should bring significant innovation and benefits. However, money laundering and criminal activities undermine public and investor trust in blockchain, affecting the healthy development of the market.
Protecting the Legitimacy of Cryptocurrencies: If the blockchain and cryptocurrency industry is widely perceived as a tool for supporting crime, it could lead to stricter government intervention, impacting its innovative potential. Combating money laundering helps maintain the legitimacy of blockchain and public trust.
Measures Taken by Countries to Combat Blockchain Money Laundering
Anti-Money Laundering Laws (AML) and KYC Regulations
Countries around the world generally require cryptocurrency exchanges and financial service providers to comply with strict **Anti-Money Laundering (AML) and Know Your Customer (KYC)** regulations. Cryptocurrency exchanges must verify user identities and monitor and report suspicious transactions.
The Financial Action Task Force (FATF) recommends: FATF advises countries to implement strict KYC and AML compliance requirements for cryptocurrencies and to enforce the "travel rule," which necessitates the collection and sharing of identity information for both parties involved in cryptocurrency transfers.
Blockchain Tracking and Analysis Technologies
The public and transparent nature of blockchain actually becomes key in tracking money laundering activities. Law enforcement agencies collaborate with third-party companies (such as Chainalysis and Elliptic) to use blockchain analysis technologies to trace fund flows and identify wallet addresses and transactions associated with illegal activities.
On-Chain Analysis: Using on-chain analysis tools, law enforcement agencies can track complex fund flows, identify addresses used by money launderers, and ultimately trace the source of illegal funds.
International Cooperation and Information Sharing
Governments, international organizations (such as the FATF and the United Nations), and financial institutions collaborate to establish a global anti-money laundering framework to combat cross-border money laundering activities conducted through blockchain. International cooperation aids in tracking funds flowing across different jurisdictions, preventing criminals from using cross-border advantages to evade detection.
