EU Chat Control Could Erode Trust and Possibly Push Users Toward Ethereum-Based Web3 Platforms

• Client‑side scanning mandates can undermine end‑to‑end encryption and user trust.

• Privacy experts warn the proposal conflicts with Articles 7–8 of the EU Charter on confidentiality and personal data protection.

• 15 EU countries support the proposal; Germany’s vote will likely decide passage.

Chat Control law risks encryption and user trust in messaging—learn how Web3 privacy could gain users and what Germany’s vote means. Read expert analysis and next steps.

What is the Chat Control law and how would it affect encryption?

Chat Control law is a proposed EU Regulation to Prevent and Combat Child Sexual Abuse that would require platforms to scan private messages before encryption, using client‑side scanning tools. This change could weaken end‑to‑end encryption guarantees and reduce public trust in mainstream messaging services.

How does client‑side scanning work and why do experts object?

Client‑side scanning inspects content on user devices prior to transmission. Experts say it creates a de facto backdoor because monitoring occurs before encryption, giving third parties or systems visibility into private data.

Hans Rempel, co‑founder and CEO of Diode, warned that handing “nearly unlimited visibility into the private lives of individuals” to systems is incompatible with digital privacy. Elisenda Fabrega, general counsel at Brickken, noted conflicts with Articles 7 and 8 of the EU Charter of Fundamental Rights.

Why could the Chat Control law push users toward Web3 privacy solutions?

Users may lose trust in centralized platforms if private messages are actively scanned. Privacy‑focused users often migrate to systems that provide stronger cryptographic guarantees and data self‑custody — core principles of Web3 privacy.

Rempel summarized the shift as “Not your keys, not your data,” highlighting how decentralized platforms preserve user control and reduce single‑point surveillance risks.

When will the EU decide and what role does Germany play?

The final vote depends on EU member state support and population thresholds. Fifteen countries currently back the proposal but have not reached the required 65% population threshold.

Germany holds the pivotal vote. If Germany supports the proposal the regulation will likely pass; if it abstains or opposes, the measure is expected to fail.

Frequently Asked Questions

Could Chat Control be justified under EU law?

Legal experts argue it is difficult to justify. Critics point to potential conflicts with the Court of Justice jurisprudence and Articles 7–8 of the EU Charter, which protect confidentiality of communications and data privacy.

What immediate steps can users take to protect privacy?

Use privacy‑focused messaging with open‑source clients, enable local device protections, back up keys securely, and explore decentralized platforms that emphasize self‑custody and client‑side encryption.

Key Takeaways

• Encryption at risk: Client‑side scanning would weaken end‑to‑end encryption promises and increase surveillance exposure.
• Trust shift: Erosion of trust in centralized platforms may accelerate migration to decentralized Web3 alternatives.
• Decisive vote: Germany’s stance will likely determine whether the regulation passes; currently 15 countries support it but not the required threshold.

Conclusion

The proposed Chat Control law raises technical and legal concerns that could undermine encryption and drive users toward decentralized Web3 privacy solutions. Policymakers must weigh child protection goals against fundamental privacy rights and technological feasibility. Watch Germany’s vote and consider privacy best practices while the debate continues.
