Decentralized Bypass Tools: How Iranians Are Breaking Through the "Digital Iron Curtain" During Protests

When the Iranian government shut down the entire internet in January of this year, millions of citizens lost contact with the outside world. But creative individuals did not voluntarily give up. They turned to bypass tools and decentralized technologies to continue sending messages, sharing videos, and connecting with the international community. This was not an isolated case but a widespread phenomenon: reports indicate that nearly 90% of Iranians have used at least one form of alternative network access tool to escape government censorship.

When the Internet Goes Down: Routing Tools Become Lifelines

On January 8th, Iranian authorities made the most drastic decision in nearly 50 years of rule: shutting down nationwide internet access. This move was a response to the surge of protests that erupted the previous month, as the national currency collapsed and economic conditions worsened rapidly.

A pseudonymous user named Darius, a long-time member of the Persian-speaking community, described the desperate early days: “We are living in hell—no internet, no money, no media. People cannot fight back with their bare hands.” However, Darius did not give up. He continuously switched between different network tools to take advantage of brief windows when the internet was restored. Through this technique, he managed to send a few critical messages via Telegram while the government was forced to balance censorship with the need to keep the economy running.

Adam Burns, co-founder of the Australian Internet Society, explained that the Iranian government had two goals in implementing the shutdown: “This is standard media control—mainly to prevent organized protests and to keep international awareness at bay. Essentially, it’s a form of risk management.”

OpenVPN, Shadowsocks, V2Ray: Three Options to Escape Censorship

To bypass the government’s firewall, Iranians like Darius used a variety of tools, each with different mechanisms:

OpenVPN is the most widely used tool to hide users’ IP addresses, helping to conceal their true identities. It creates an encrypted tunnel that protects all data traffic.

Shadowsocks operates based on the SOCKS5 protocol, transforming network requests into random data, making it difficult for surveillance systems to detect and block. This tool is especially effective in highly censored environments.

V2Ray takes a more sophisticated approach: it disguises network requests as regular traffic, directing them to legitimate websites that the government cannot block. Darius used this technique to emulate his requests as normal electronic transactions, then encrypted and routed the data through tunnels to servers abroad.

However, these tools are not completely foolproof. Darius noted, “As soon as the traffic pattern shows an unauthenticated connection, it gets cut immediately.” This creates a constant game of cat and mouse between government engineers and those trying to bypass censorship.

Decentralized Networks: Why Starlink and Distributed Systems Are Hard to “Turn Off”

While traditional bypass tools require ongoing updates to avoid detection, a different solution has emerged: decentralized technology. These networks are exponentially more resilient than centralized ones, which rely on a single database or a single point of failure.

To break a decentralized network, the government must shut down each individual node that stores data or impose a complete nationwide internet ban. This approach is nearly impossible in a context where the government needs to maintain some network connectivity for economic activity to continue.

The decentralized Virtual Private Network (dVPN) Sentinel has become an important option. Aleksandr Litreev, CEO of Sentinel, emphasized: “Providing access to a high-resilience decentralized network helps resist even the strictest censorship. We enable information to keep flowing, allowing brave Iranians to record and share the violence being hidden behind the blackout.”

Another solution is Starlink, the satellite network operated by SpaceX. Since Starlink does not rely on a single local node, its distributed infrastructure can still provide critical connectivity even under intense censorship.

Currency Collapse, Protests Erupt: Roots of Iran’s Turmoil

To understand why Iranians are willing to take the risks of using bypass tools, one must look at the economic and political backdrop. The crisis did not start with idealistic political issues but from the harsh daily realities.

By late 2025, the Iranian rial had plummeted to an all-time low: 1 US dollar was worth 1.4 million rials. This collapse resulted from strict international sanctions targeting Iran’s nuclear program, combined with poor financial management by leaders. “It’s like owning a worthless cryptocurrency listed only on isolated exchanges,” Darius described. “Prices keep falling, and eventually, you have to use this money to buy milk and meat. Worse, the next day, you need even more money to buy the same things.”

On December 28th, Iranians gathered at Tehran’s Bazaar to protest the government’s handling of the financial crisis. The protests quickly spread to many cities, reflecting deep public discontent.

Tallha Abdulrazaq, a researcher at the Institute for Strategy and Security at the University of Exeter, explained: “Usually, people don’t revolt over lofty ideals like democracy or universal suffrage; they protest because of issues that directly affect their daily lives. As long as basic needs are met and they still have hope for the future, people are willing to live under an authoritarian regime.”

The Cat-and-Mouse Game: Are Tools Powerful Enough?

After the internet shutdown in January, the Islamic Revolutionary Guard Corps and Basij forces began using live ammunition to disperse protests. Due to the internet blackout, both on-the-ground citizens and many human rights organizations faced difficulties verifying the exact death toll.

Reports from various sources give different estimates: Human Rights Watch reports at least 3,428 deaths; Iran International cites internal documents indicating at least 12,000 deaths; and two senior health officials from Iran’s Ministry of Health claim the death toll could reach 30,000 in the first two days.

Despite the differing figures, the common point is that large-scale violence occurred. And bypass tools, along with decentralized networks, played a crucial role in allowing videos and information to escape the “iron curtain” and inform the world about what was happening in Iran.

However, when the complete internet blackout persists, almost no tools can operate. This creates a dilemma for the government: maintaining a total ban on the internet would cost billions in economic damage; reopening the connection would allow the rapid spread of information about violent actions.

“This is an endless game of cat and mouse,” Burns observed. Citizens keep finding new ways to bypass blocking tools, while the government continues developing new censorship methods. Amid this struggle, bypass machines and decentralized technologies have proven that they are not just technical tools but symbols of fundamental human needs: connection, information, and voice.
