Opinion Piece: “Web3/Blockchain Under Scrutiny: When the Fight Against Drug Trafficking Threatens Innovation”

In the coming days, the National Assembly will debate a bill aimed at combating drug trafficking. A legitimate and necessary goal. But once again, the temptation to lump everything together risks dragging a strategic sector into a punitive and unfounded regulatory spiral. Far from targeting only criminals, this bill equates any use of crypto-assets with potential support for drug trafficking, thereby casting widespread suspicion on an entire technological ecosystem.

A dangerous conflation and a violation of fundamental rights

The argument that crypto-assets significantly facilitate the financing of drug trafficking has no solid basis. All available data show that cash remains the primary vehicle for these illegal activities. Yet, the proposed bill introduces a presumption of money laundering for any transaction involving anonymized crypto-assets. This provision reverses the burden of proof and requires users to justify the legitimate origin of their funds after the fact, under penalty of sanctions.

Such an approach violates several fundamental principles of law. First, the presumption of innocence, which prohibits treating suspicion as a general rule. Second, the principle of proportionality in sanctions, which requires that any restriction be strictly justified. Finally, equality before the law: why should users of crypto-assets be subject to a more restrictive regime than cash transactions, the primary channel for money laundering in drug trafficking? It should be noted that the right to privacy in financial transactions is also protected by several fundamental legal texts, notably Article 8 of the European Convention on Human Rights and Article 7 of the Charter of Fundamental Rights of the European Union.

Jeopardize France’s technological progress and digital sovereignty

Similarly, the notion that crypto-assets are beyond any form of control is a myth. Unlike cash, blockchain is the ultimate tool for traceability. Every transaction is recorded on it in an indelible and accessible manner. Blockchain analysis technologies make it possible to identify and track suspicious financial flows, offering authorities a far more effective tool than opaque traditional financial channels. Instead of leveraging these tools to identify criminals, the bill bans technologies that, when used properly, are precisely what will enable a more effective fight against money laundering in the future.
Restricting transaction anonymization without distinguishing between lawful and unlawful uses sets a dangerous precedent. This approach penalizes law-abiding citizens, including journalists, whistleblowers, and political activists in repressive environments.

As a result, this legislation protects neither citizens nor the economy; rather, it diverts attention from the real tools for combating crime by weakening a strategic sector. While the fight against drug trafficking is a priority, it must not lead to a race to the bottom in digital innovation. By reducing Web 3.0 to a caricature of a “no-go zone,” France is inflicting a double penalty on itself: the loss of economic competitiveness and the erosion of fundamental freedoms. Web 3.0 cannot be made the scapegoat for criminal abuses when it offers precisely the solutions to better combat them.

A call for measured and constructive regulation

France has the opportunity to position itself as a European leader in these technologies by developing a smart and pragmatic regulatory framework. It is time to support an ecosystem that is already heavily regulated and is just waiting to grow with the confidence of public authorities.

If this bill were to be adopted as is, it would undoubtedly be challenged on constitutional grounds, and possibly even before European courts. Legislation cannot be based on vague generalizations and oversimplifications; it must be grounded in objective facts and respect the principles of our rule of law.

It is therefore imperative that lawmakers re-evaluate this bill and adopt regulations that are proportionate, effective, and in line with European standards. Effective regulation relies on a thorough understanding of the issues at stake and constructive cooperation between private entities and public authorities—not on stigmatization.
