Vitalik Buterin has sparked intense debate after highlighting Iran’s powerful surveillance infrastructure, which allegedly tracks over 90 million mobile users without warrants. Recent reports claim Iranian authorities were able to identify and intimidate protesters in late 2025 using nothing more than mobile network data—no phone seizures, no informants required.
According to a February 13, 2026 investigation by The New York Times, officials relied heavily on cell tower records to monitor protest attendance. Following a nearly 20-day nationwide internet blackout, arrests reportedly began in a systematic manner. Interrogators were said to possess facial recognition matches, location histories, and even social media evidence.
🔍 SIAM: The Silent Engine Behind the System
At the center of the controversy is SIAM (Subscriber Identity and Activity Monitoring), a platform embedded directly into Iran’s telecom infrastructure. Originally exposed in the 2022 “Iran Cables” leak reported by The Intercept, the system allegedly provides authorities with real-time access to:
📍 User location data
📞 Call records
🌐 Internet browsing activity
💳 Financial behavior
Reports suggest operators can also take direct action—such as disabling SIM cards, forcing devices onto slower 2G networks, or redirecting calls to government lines. In short, the platform doesn’t just observe activity; it can actively control it.
A typical protest tracking flow is highly structured. Devices near demonstrations are logged via SIAM’s LocationCustomerList feature. Nearby IMSI catchers silently collect device identifiers, while CCTV feeds run facial recognition checks against national ID databases. Weeks or months later, authorities may act—timed strategically to amplify fear and discourage dissent.
🌐 Foreign Tech Links
Iran’s surveillance ecosystem reportedly relies in part on foreign infrastructure.
A February 2026 report by ARTICLE 19 states that Chinese firms including Huawei and ZTE helped supply hardware and architectural support for Iran’s National Information Network — a domestic internet capable of operating independently from the global web.
Meanwhile, Russian firm PROTEI reportedly provided deep packet inspection (DPI) systems and mobile signaling tools. DPI technology enables authorities to throttle encrypted apps like Signal or Telegram while allowing state-approved platforms to function normally.
⚠️ Buterin’s Warning: The Power Shift
On X, Buterin emphasized that the real risk of surveillance is often misunderstood. He argued the danger isn’t just “dystopian optics” — it’s the fundamental shift in the balance of power between citizens and the state.
According to his analysis, when automated surveillance merges with authoritarian control, a regime could theoretically maintain power with an extremely small supporting coalition. In such a model, drones, cameras, and algorithmic enforcement replace large traditional enforcement structures.
He also drew a distinction between surveillance models:
Territorial high-control systems (like Iran)
Broad but shallower global monitoring (often attributed to Western intelligence)
Both raise concerns, but the former may pose a more direct threat to political pluralism.
🌍 Why This Matters for Crypto and Privacy
The biggest takeaway: surveillance tech scales globally.
Tools such as:
Deep packet inspection
Facial recognition
IMSI catchers
Network-level tracking
…can be exported and deployed anywhere. What is refined in one country today may become standard infrastructure elsewhere tomorrow.
Buterin suggested that advancing privacy tech and censorship-resistant internet infrastructure — potentially treating basic internet access as a human right beyond strict nation-state control — could help mitigate long-term risks. However, he acknowledged there is no perfect solution yet.
🧭 Final Thoughts
Iran’s case demonstrates that mass digital surveillance is no longer theoretical — it is operational and evolving. The key question now is not whether governments can deploy such systems, but how rapidly this model spreads worldwide.
For the crypto and privacy community, the stakes are becoming increasingly global.
