Ethereum co-founder Vitalik Buterin has issued a stark warning against a highly controversial European Union proposal that would mandate the scanning of all private digital messages. Known informally as “Chat Control,” the regulation is being promoted as a tool to fight child sexual abuse, but Buterin and a growing chorus of privacy advocates argue that it would dismantle the foundations of digital privacy and create massive security risks for every citizen.
What Exactly is ‘Chat Control’?
The proposal, officially titled the Regulation to Prevent and Combat Child Sexual Abuse (CSAR), would compel technology companies to implement systems that scan all user content. This includes private messages, photos, and links sent through messaging platforms like WhatsApp, Signal, and Telegram—even those that use end-to-end encryption. The goal is to automatically detect and report potential child sexual abuse material (CSAM). While the objective is widely supported, the method of mass surveillance has sparked fierce opposition.
A Cure Worse Than the Disease?
Buterin believes the proposal is a complete failure, noting that you cannot make communities more secure by making communications of its members more insecure. He warns that forcing companies to build systems capable of scanning encrypted messages effectively creates a “backdoor” that undermines the very purpose of encryption.
He elaborated in detail by suggesting that these measures create novel and unanticipated dangers. The enormous body of intercepted and scanned information would become a hacker’s, criminal, and even unfriendly foreign government’s target for future data breaches.
‘Common-Sense Policing’ Over Mass Surveillance
Instead of what he considers a reckless digital dragnet, Buterin believes that a better alternative is enhanced traditional law enforcement. He cited “common-sense policing improvements” or judicial changes to avoid the release of habitual offenders as a much better way to enhance public safety. In his view, the question is not if we can surveil every citizen’s conversations presume to take every citizen’s private conversations as being suspicious but rather if we can conduct surveillance on investigations that are based on evidence. He also indicates that individuals deserve privacy online that is equivalent to privacy in face-to-face interactions.
The Controversy of Exemptions
Following leaked 2024 internal territorial report urging several EU interior ministers to seek an exemption for their individual’s government agencies, police, military, and intelligence officers; concerns over the proposal have intensified. Critics began to point to this as example of blatant misuse or hypocrisy. Privacy advocates argue that if lawmakers believe the surveillance system is too dangerous and invasive for their own communications, it is tyrannical to impose it on the general public. Pratam Rao, co-founder of the security firm QuillAudits, noted, “They’re admitting these systems are dangerous to privacy and democracy.”
A Deeply Divided Europe
With Buterin requesting all EU citizens to speak out against the bill, the geopolitical landscape continues to be fragmented. The proposal has a long way to go before there is a consensus among member states in the bloc. According to data from the advocacy group FightChatControl.eu, only seven countries, including Austria and Finland, have formally rejected the proposal. In contrast, 12 nations, such as France and Spain, have voiced their support. With key countries like Germany and Italy still undecided, the future of digital privacy in Europe hangs in the balance, caught between the desire for security and the fundamental right to a private conversation.
