Money Laundering Via Digital Currencies And Blockchain Platforms
I. Introduction
Money laundering via digital currencies and blockchain platforms is a growing concern due to the pseudonymous nature of transactions, cross-border accessibility, and difficulty in tracing funds. Criminals often use these platforms to move illicit funds, evade regulatory oversight, and obscure ownership.
Key mechanisms for digital money laundering:
Cryptocurrency exchanges – converting fiat to crypto and vice versa.
Mixers/tumblers – anonymizing transactions to hide sources.
Decentralized Finance (DeFi) platforms – lending, staking, and liquidity pools used for obfuscation.
Initial Coin Offerings (ICOs) and NFTs – laundering through token sales or digital assets.
Peer-to-peer transactions – bypassing regulated exchanges.
Legal challenges:
Tracing pseudonymous blockchain transactions
Jurisdictional issues across countries
Evolving regulatory frameworks (FATF, FinCEN, EU AML directives)
II. Legal Frameworks
Bank Secrecy Act (BSA, U.S.) – reporting of suspicious financial activity
USA PATRIOT Act – includes cryptocurrency transactions
EU Anti-Money Laundering Directives – virtual asset service providers (VASPs) regulation
Financial Action Task Force (FATF) Guidelines – Travel Rule for digital assets
National regulations – AML laws in countries like Singapore, Japan, India
Prosecution principles:
Tracing illicit funds on blockchain
Demonstrating intent to conceal or disguise
Linking pseudonymous wallets to real-world identities
Applying traditional money laundering statutes to digital assets
