Chainalysis analysis of ~400 crypto wallets of CSAM sellers: revenue is down since 2021, but sellers are using mixers and privacy coins to evade law enforcement
Crypto tracing firm Chainalysis found that sellers of child sexual abuse materials are successfully using “mixers” and …
Context & Ripple Effects
This analysis extends a long-running enforcement story in which Chainalysis tracing helped identify users of a dark-web CSAM site, including in the Welcome to Video investigation. Earlier coverage also showed how exchange access could support a major CSAM marketplace, the Dark Scandals case.
The reported revenue decline suggests pressure on this activity, but the shift toward obfuscation tools means lower proceeds do not necessarily make transactions easier to investigate.
First-order effects
- CSAM sellers using mixers and privacy coins make transaction trails harder for investigators and analytics providers to follow than straightforward transfers.
- Chainalysis’s findings pair a decline in seller revenue since 2021 with evidence that the remaining activity is adapting its payment methods to reduce traceability.
Second-order effects
- Exchanges and other crypto services face stronger incentives to identify exposure to mixer-linked funds, since they can be a point where obscured assets re-enter more traceable markets.
- The findings reinforce law-enforcement scrutiny of mixing infrastructure; later coverage of the Samourai Wallet charges illustrates how that scrutiny can target services alleged to facilitate laundering.
Third-order effects
- If criminal users continue moving from transparent chains into obfuscation tools, crypto compliance will increasingly hinge on the boundary between traceable service providers and privacy-preserving transaction infrastructure.
- The durable policy tension is the crypto legitimacy gap: efforts to preserve lawful privacy will face sustained pressure from investigations involving severe illicit activity.
The trend: This is one data point in the widening contest between blockchain-tracing capabilities and privacy tools designed to break those investigative trails.
