TL;DR: Illicit crypto transactions totalled $40.9 billion in 2024, while many law enforcement agencies still lack the tooling and workflows to investigate blockchain-linked crime effectively, according to Chainalysis. The operational gap is less about visibility into the ledger and more about converting transaction data into accountable investigative action.
NHIMG editorial — based on content published by Chainalysis: Crypto Investigations, Blockchain Intelligence for Law Enforcement
By the numbers:
- In 2024, transactions linked to illicit activity totaled $40.9 billion.
Questions worth separating out
Q: How should organisations investigate crypto-related crime without losing evidentiary quality?
A: Organisations should pair blockchain tracing with documented evidence handling, clear ownership, and case-management workflows.
Q: Why do wallet and exchange access controls matter in crypto investigations?
A: Because wallets, exchange accounts, API keys, and recovery channels determine who can move or freeze assets.
Q: What do security teams get wrong about blockchain intelligence?
A: They often treat it as a visibility problem instead of a governance problem.
Practitioner guidance
- Map wallet, exchange, and API access to named owners Create an inventory of all wallets, exchange accounts, recovery methods, and analytics service accounts, then assign accountable owners and review cycles.
- Preserve investigative provenance for every tracing step Record which addresses, heuristics, clustering assumptions, and external sources were used to reach each conclusion.
- Integrate blockchain intelligence with fraud and sanctions workflows Do not leave crypto tracing isolated in a specialist team.
What's in the full article
Chainalysis's full research covers the operational detail this post intentionally leaves for the source:
- The report's practical breakdown of how blockchain intelligence supports investigations across scams, ransomware, laundering, sanctions evasion, and darknet commerce.
- The source's explanation of where crypto and crime intersect in transaction tracing, clustering, and attribution workflows.
- The article's guidance on what practitioners should evaluate in a blockchain intelligence solution before operational rollout.
- The paper's examples of how law-enforcement agencies are already using these techniques in real investigations.

Blockchain intelligence is becoming a control layer, not just an investigative tool. Law enforcement and regulated enterprises increasingly need evidence-grade transaction analysis, not just dashboards. The practical shift is from visibility to actionability, where analytics must support containment, recovery, sanctions response, and prosecution-ready documentation.
A question worth separating out:
Q: Who is accountable when crypto-related fraud or laundering is detected?
A: Accountability usually spans security, fraud, compliance, legal, and platform operations because each owns a different part of the control chain. A usable response model defines who can preserve evidence, who can escalate to exchange partners, and who can approve external referrals.
