September 26, 2025 - Dynamic Internet Technology Releases Tool to Identify Contributors to China’s “Great Firewall”

Revealing authorship, source projects, and code contributions behind the world’s most expansive system of censorship and repression

New York, Sep. 26, 2025 — Dynamic Internet Technology (DIT), a pioneer in circumvention technologies, today announced the release of a tool that identify the individual authors who contributed code to China’s “Great Firewall” (GFW). The tool provides unprecedented transparency, showing which developers worked on which git projects, and quantifying their contributions by lines of code.

The code analyzed originates from the recent leak of MESA Lab, a research institute under the Chinese Academy of Sciences. This 600GB leak of China’s Great Firewall reveals in unprecedented detail how the country systematically builds and manages its censorship and surveillance infrastructure, while also exporting these tools to countries like Myanmar, Pakistan, Ethiopia, and Kazakhstan. This repository confirms the direct involvement of state-linked researchers and developers in building and maintaining censorship technologies at the core of the GFW.

“Our tool shines a light on the hidden architecture of censorship,” said Bill Xia, CEO of Dynamic Internet Technology. “The Great Firewall affects not only the freedom of Chinese citizens, but also the openness of the international internet economy. For example, while Americans can freely visit Chinese websites, Chinese users are blocked from accessing U.S. platforms. This imbalance harms innovation, trade, and the principle of an open internet. More gravely, the blocking of uncensored information facilitates the Chinese Communist Party’s human rights atrocities, by silencing independent voices and concealing the truth from its own people.”
Beyond informing researchers and journalists, the transparency enabled by this tool may also support government and policy responses. By identifying individuals and institutions who helped build and maintain the GFW, the findings could contribute to discussions on accountability—including potential sanctions or other measures aimed at those enabling mass censorship and human rights violations.

The new DIT tool allows journalists, researchers, and policymakers to:
• Trace contributions by specific authors.
• Measure their involvement by lines of code.
• Map development work across multiple git projects tied to the GFW.

The Great Firewall is the informal name for China’s nationwide internet censorship and surveillance infrastructure. More than a technical system, it has become a central instrument of political control—blocking access to uncensored news, suppressing free expression, and enabling the Chinese Communist Party (CCP) to conceal human rights abuses from both domestic and international audiences.

The GFW’s impact is twofold. Within China, it denies citizens the basic right to seek truth and voice dissent, creating an environment where human rights violations can occur without scrutiny. Internationally, it distorts fair competition, forcing foreign businesses to operate under censorship demands, while Chinese companies freely access global markets. Americans, for example, are free to visit Chinese websites, but Chinese citizens are blocked from accessing U.S. platforms—an asymmetry that harms both open commerce and democratic values.
