Definition ∞ Mixer usage refers to the employment of cryptocurrency mixers, also known as tumblers, which are services designed to obscure the transaction history of digital assets. These services pool funds from multiple users and then redistribute them, making it difficult to trace the origin and destination of specific coins. While some users seek privacy, mixers can also be utilized for illicit activities, such as money laundering. This practice complicates forensic analysis of blockchain transactions.
Context ∞ Mixer usage is a contentious topic in regulatory and law enforcement discussions, often associated with efforts to combat financial crime within the digital asset space. News frequently covers debates regarding the legality and ethical implications of these services, particularly concerning anti-money laundering AML and know-your-customer KYC compliance.
