EU Adopts “Chat Control”: Surveillance of Private Communications Authorized Until 2028 — A Shock to Encryption and Privacy
Publication date: July 10, 2026 — 12:00 UTC
Brussels has crossed a historic and controversial threshold in digital regulation. This Friday, July 10, 2026, the European Parliament and the Council of the European Union definitively adopted the regulation known as “Chat Control” — a law that allows authorities to carry out automated detection of illegal content in encrypted private communications, including messages, photos, and videos exchanged via WhatsApp, Signal, Telegram, and other secure messaging platforms. The measure, valid until 2028, plunges the crypto community and privacy advocates into an unprecedented shockwave.
What Exactly Does “Chat Control” Contain?
The regulation, officially titled “Regulation on the Prevention and Detection of Child Sexual Abuse Online,” requires messaging service providers and communication platforms to implement automated detection mechanisms for child sexual abuse material, as well as terrorist content and other serious offenses. In practice, messaging services will have to scan private conversations — including those protected by end-to-end encryption — to identify prohibited content.
This obligation, originally set to expire in 2026, has been extended until 2028, thus providing an unprecedented legal framework for mass surveillance of private communications within the European Union. Technology companies that fail to comply with these requirements face fines of up to 6% of their global annual turnover.
A Gaping Hole in End-to-End Encryption
What makes this legislation particularly explosive is its direct impact on end-to-end encryption (E2EE), a fundamental pillar of digital security and privacy. Until now, messaging services like Signal, WhatsApp, Telegram, and iMessage guaranteed that only the sender and recipient could read the content of messages — not the provider, not the authorities, and no third party.
With “Chat Control,” the European Commission imposes what it calls “client-side scanning.” In practice, this means that software installed on the user’s device — whether a smartphone, tablet, or computer — will have to analyze messages before they are encrypted and sent, or after they are decrypted by the recipient. This mechanism, presented as a technical solution, is heavily criticized by cryptographers and security experts who see it as a disguised backdoor.
“Client-side scanning is the death of end-to-end encryption as we know it,” explain experts interviewed by CoinTelegraph. Once third-party software can inspect message content before encryption, the very notion of private and secure communication collapses. What was presented as a targeted measure becomes, de facto, a generalized surveillance infrastructure.
Immediate Repercussions on the Cryptocurrency Market
The adoption of this regulation has caused immediate tremors in cryptocurrency markets, as investors grasp the deep implications of this legislation for the crypto ecosystem. Bitcoin (BTC) was trading around $63,950 on Binance at 18:00 UTC, while Ethereum (ETH) was trading at approximately $1,791 on the same platform — levels that reflect palpable nervousness in the industry.
Several sectors of the crypto market are directly threatened by this regulatory development. First and foremost, privacy coins — cryptocurrencies specialized in transaction anonymity, such as Monero (XMR), Zcash (ZEC), or Dash (DASH) — could face increased scrutiny. If European authorities are now empowered to demand scanning of private communications, it is plausible to think that privacy coin transactions, often associated with advanced encryption protocols, could be next on the list.
Centralized exchanges operating in Europe could also see their KYC (Know Your Customer) obligations further strengthened. With the ability to scrutinize conversations, regulatory authorities might require trading platforms to share communications from users suspected of money laundering or financing illicit activities via cryptocurrencies. Exchanges like Binance, Coinbase, and Kraken, which already have strict KYC obligations, may need to integrate communication surveillance mechanisms into their compliance processes.
A Dangerous Precedent for On-Chain Surveillance
Beyond privacy coins and centralized exchanges, the entire philosophy of blockchain is being called into question. Blockchain has historically been based on principles of transparency and permissionless innovation — but also pseudonymity and individual sovereignty. “Chat Control” sets a worrying regulatory precedent: if private communications can be systematically analyzed for illegal content, why should on-chain transactions not also be subject to the same treatment?
European authorities have already shown growing ambition in monitoring digital assets. The MiCA regulation (Markets in Crypto-Assets) has significantly strengthened transaction traceability and reporting obligations. With “Chat Control,” the EU lays the groundwork for a surveillance infrastructure that could, in the long term, be extended to distributed ledgers themselves. DeFi (decentralized finance) protocols, which enable intermediary-free exchanges, could be forced to integrate address filtering mechanisms or block transactions from wallets deemed suspicious.
Crypto projects based on advanced encryption technologies, such as layer-2 solutions, zero-knowledge proofs (ZK-proofs), and privacy protocols, also find themselves in the spotlight. The paradox is striking: while blockchain technology innovates to offer ever more privacy and financial sovereignty, European regulation takes the opposite direction.
The Untenable Position of Messaging Giants
The consequences of this legislation extend far beyond the crypto sphere. Companies like Meta (WhatsApp), Apple (iMessage), Microsoft (Skype), and Telegram find themselves in an untenable position. On one hand, they must comply with European legislation under threat of massive financial penalties. On the other, they must maintain user trust, which expects increasingly higher levels of security and privacy.
Telegram, which has already developed crypto features like an integrated wallet and Toncoin (TON) transactions, is particularly exposed. The app, very popular in crypto communities, could be forced to compromise its encryption to comply with European regulations, dealing a severe blow to its positioning among privacy-conscious...
