Operation Lighthouse Investigates Over 29,000 Crypto Addresses

Operation Lighthouse, a blockchain‑analytics sprint led by Chainalysis, examined 29,120 cryptocurrency addresses and other digital identifiers. The effort produced 14,300 investigative leads and identified more than 7,700 suspect accounts linked to child sexual abuse material (CSAM) across 125 countries.

Scope and Participants

The sprint was hosted by the National Cyber‑Forensics and Training Alliance in New York and brought together investigators from at least nine law‑enforcement agencies, over 13 private‑sector partners, and specialized nonprofits. Participants included Europol, the Australian Federal Police, the Royal Canadian Mounted Police and the United Kingdom’s National Crime Agency.

Key Outcomes

• 29,120 crypto addresses and identifiers examined.
• 14,300 investigative leads generated across 11 exchanges and payment services.
• More than 7,700 suspect accounts identified.
• Suspects located in 125 countries.
• Private‑sector partners flagged 16 registered sex offenders; two companies identified at least 150 individuals.

Context and Prior Operations

Previous blockchain‑forensic investigations have led to arrests and platform disruptions, such as the Europol‑supported Kidflix operation (≈1,400 suspects, 79 arrests) and a multinational crackdown on the AudiA6 laundering service (≈10,333 BTC traced). These cases illustrate how public transaction records, when combined with exchange and payment‑provider data, can produce actionable leads.

Future Implications

Operation Lighthouse established a shared process for law‑enforcement, cryptocurrency companies and nonprofits to examine common leads. Chainalysis expects the generated leads to result in account restrictions, arrests and prosecutions through 2027, and plans to apply the sprint model to other illicit crypto activities.
