The European Union is once again debating its controversial Chat Control proposal, reopening discussions that could extend temporary rules allowing online platforms to scan private messages for child sexual abuse material until 2028. While the proposal is aimed at strengthening child protection, it has sparked renewed concerns among privacy advocates, cybersecurity experts, and the cryptocurrency industry.
Critics argue that expanding message-scanning requirements could weaken encryption, increase security risks for digital assets, and place new compliance burdens on blockchain developers. As the European Parliament prepares for another vote, the outcome could have significant implications for both online privacy and the future of Web3 services.
EU Parliament prepares for another vote
According to Euronews, the European Parliament approved an urgent procedure on Tuesday, paving the way for a new vote on Thursday to decide whether the temporary ePrivacy derogation should remain in effect until 2028.
The existing legal framework expired in early April, leaving online platforms free to continue scanning for child sexual abuse material on a voluntary basis rather than under a temporary EU mandate.
The procedural motion passed by a narrow margin:
- 331 lawmakers voted in favor
- 304 voted against
- 11 abstained
Pirate Party Member of the European Parliament Markéta Gregorová criticized the move, arguing that Parliament was revisiting a proposal it had already rejected earlier this year.
She also noted that any attempt to reject or amend the proposal now requires an absolute majority of 361 votes, making it significantly harder for opponents to block the extension.
Why the proposal returned
The debate resurfaced after the European People’s Party (EPP) backed another effort to extend the temporary rules.
According to Euronews, EPP leader Manfred Weber sought to revive the legislation without several amendments that contributed to its earlier rejection in March.
Separately, EU member states agreed last month to support an interim framework that would continue allowing online service providers to detect, report, and remove child sexual abuse material until 2028 while negotiations over permanent legislation continue.
If Parliament approves the extension, messaging platforms may once again operate under a formal EU legal framework rather than relying solely on voluntary monitoring.
Potential impact on crypto and Web3
Although the proposal primarily targets online messaging platforms, many in the blockchain industry believe its impact could extend far beyond traditional communication services.
If adopted, Web3 projects offering:
- Wallet-based messaging
- Decentralized social media
- Encrypted communication tools
could face new compliance requirements.
Developers may be forced to introduce content monitoring systems or restrict certain services for users within the European Union.
Some industry participants also worry that similar legal principles could eventually be applied to blockchain transaction data and smart contract infrastructure.
Privacy concerns remain a major issue
The proposed rules have drawn criticism from privacy advocates who argue that scanning private communications could weaken end-to-end encryption.
Ethereum co-founder Vitalik Buterin has previously warned that introducing systemic backdoors into encrypted communication systems ultimately reduces security for everyone rather than improving it.
He has also questioned reports suggesting certain government officials could receive exemptions from the proposed requirements, arguing that such exceptions would undermine the consistency of the legislation.
Blockchain industry warns of new security risks
The International Association for Trusted Blockchain Applications (INATBA) has also expressed concerns about the proposal, particularly regarding client-side scanning.
Unlike traditional content moderation, client-side scanning examines messages, images, and files on a user’s device before they are encrypted.
According to INATBA, integrating such technology into operating systems or applications could introduce new attack surfaces that hackers might exploit.
Potential risks include exposure of:
- Crypto wallet seed phrases
- Session keys
- Multi-Party Computation (MPC) shares
The organization also warned that mandatory scanning requirements could create additional legal liabilities for open-source wallet developers and decentralized application builders if security vulnerabilities emerge.
Innovation could shift outside Europe
Beyond security concerns, blockchain organizations argue that stricter compliance obligations may discourage innovation across Europe’s digital asset industry.
According to INATBA, additional regulatory burdens could slow the development of privacy-preserving technologies such as zero-knowledge proofs while encouraging blockchain developers and Web3 companies to relocate projects outside the European Union.
Many in the industry believe maintaining strong encryption remains essential for protecting both financial assets and user privacy.
What happens next?
The European Parliament is expected to vote on the proposal on Thursday.
If approved, the temporary framework allowing online platforms to scan communications for child sexual abuse material would remain in force until 2028, while lawmakers continue negotiating a permanent version of the legislation.
The outcome will be closely watched not only by privacy advocates and technology companies but also by the cryptocurrency industry, which sees encrypted communications as a critical component of digital asset security.
Final thoughts
The renewed debate over the EU’s Chat Control proposal highlights the growing challenge of balancing public safety with digital privacy. While lawmakers argue that extending message-scanning rules will strengthen efforts to combat online child exploitation, critics warn that weakening encryption could introduce broader cybersecurity risks.
For the crypto industry, the stakes extend beyond messaging platforms. Any regulations affecting encrypted communications may ultimately influence wallet security, decentralized applications, and the future development of privacy-focused blockchain technologies across Europe.
