Operation Lighthouse was a multi-day intelligence sprint led by Chainalysis to disrupt cryptocurrency-linked child sexual abuse material (CSAM) networks. According to Chainalysis and reports describing its results, investigators examined 29,120 cryptocurrency addresses and digital identifiers connected to more than 100 CSAM platforms, forums, and distribution networks across the surface web and dark web. The effort generated 14,300 investigative leads and flagged more than 7,700 suspect accounts linked to activity in 125 countries. 2

The figures are significant, but they should be read carefully: they describe investigative leads and suspect accounts, not proven criminal liability or completed prosecutions.
What Operation Lighthouse was designed to do
The operation focused on the financial infrastructure associated with CSAM distribution. Rather than functioning solely as a training event, it was organized as a coordinated investigative effort intended to convert blockchain data into leads that law-enforcement agencies and financial platforms could pursue. 7

The sprint was hosted at the National Cyber-Forensics and Training Alliance (NCFTA) in New York. It brought together law-enforcement agencies, cryptocurrency exchanges and payment services, private-sector firms, and specialized nonprofits, with investigators participating from multiple continents. 2

How the investigation worked
The operation rested on months of prior data enrichment followed by a concentrated, multi-day review. Investigators traced cryptocurrency addresses and other digital identifiers associated with more than 100 CSAM platforms, forums, and distribution networks operating across both the surface web and dark web. 2

The reported workflow connected blockchain analysis with information held by exchanges and payment services. That allowed participating organizations to examine potentially relevant accounts even when the illicit material itself was not hosted on a financial platform. The purpose was to produce leads that investigators could develop through additional records, corroboration, and jurisdiction-specific legal processes. 7

Who participated
Chainalysis described Lighthouse as a public-private effort involving more than nine law-enforcement agencies, more than 13 private-sector partners, and specialized nonprofits. 7 The available reporting identifies the collaboration broadly as spanning blockchain analytics, exchanges, payment services, law enforcement, and child-protection expertise.

This structure was central to the operation’s design. Blockchain data can reveal transaction relationships, while exchanges and payment providers may hold account information that investigators cannot obtain from public ledger analysis alone. Law-enforcement agencies then determine how leads can be corroborated and pursued under applicable law.
What the operation reported finding
The headline results attributed to Operation Lighthouse were:
- 29,120 cryptocurrency addresses and digital identifiers examined.

- Connections to more than 100 CSAM platforms, forums, and distribution networks.

- 14,300 investigative leads generated across 11 cryptocurrency exchanges and payment services.
7
10
- More than 7,700 suspect accounts identified.
13
- Suspect activity identified across 125 countries.
- 16 accounts reportedly linked to registered sex offenders, according to reporting that cites Chainalysis.
These numbers measure the scale of the data review and the resulting investigative workload. They do not, by themselves, show how many people will be arrested, charged, prosecuted, or convicted.
Why the public-private model matters
The operation’s broader significance is its attempt to make financial intelligence operational at international scale. A blockchain investigation may identify transaction patterns, but turning those patterns into a case often requires cooperation from exchanges, payment providers, law-enforcement agencies, and other organizations holding different pieces of evidence.
Lighthouse presents that coordination as a repeatable model: enrich the data before the operation, bring relevant partners together for an intensive investigative sprint, and distribute actionable leads for follow-up. Chainalysis says the same approach can support work against other illicit cryptocurrency typologies, although the available reporting does not independently establish how widely the model will be adopted. 7

What happens next—and what remains unproven
The immediate result is a large set of leads for investigators in multiple jurisdictions. The next steps would require corroborating blockchain indicators with exchange records, identity information, digital evidence, and other evidence obtained through lawful investigative procedures.
That distinction is particularly important in a case involving activity across 125 countries. Different legal systems, evidentiary standards, disclosure rules, and prosecutorial decisions can affect whether a lead becomes an investigation, a charge, or a conviction.
The supplied evidence does not independently document completed prosecutions or convictions arising from Operation Lighthouse. Nor does it verify forecasts about specific prosecutorial outcomes through 2027, broader growth in CSAM-related crypto flows, or increased use of privacy coins and mixing services. Those claims should therefore be treated as unconfirmed rather than as established results.
The strongest confirmed takeaway is narrower but still consequential: Chainalysis says a coordinated, multi-day investigation connected blockchain analysis with financial-sector and law-enforcement cooperation to produce 14,300 leads and flag more than 7,700 accounts. Whether that translates into durable disruption will be judged by the quality of follow-up cases—not by the initial lead count alone.
