Crypto Transparency Fuels Crime Investigations with Chainalysis Operation

Crypto is increasingly becoming an integral part of the financial infrastructure used by criminals to facilitate serious crimes, but its transparency is also making those networks easier to trace.

A Chainalysis-led investigation, dubbed Operation Lighthouse, examined 29,120 cryptocurrency addresses and digital identifiers linked to more than 100 child sexual abuse material networks. Working with Binance, Coinbase, law enforcement agencies, and other partners, the operation generated 14,300 investigative leads across 11 crypto exchanges and payment services, identified over 7,700 suspect accounts, and linked suspects to 125 countries.

The investigation highlights a broader trend in crypto crime, where cryptocurrency-related flows to suspected human-trafficking services rose 85% in 2025, reaching hundreds of millions of dollars. Stablecoins have become particularly important in some trafficking and illicit-service networks due to their price stability and ease of conversion.
