Tor is a free-software anonymizing network that helps people around the world use the Internet in safety. Tor's 9000 volunteer relays carry traffic for millions of daily users, including ordinary citizens who want protection from identity theft and prying corporations, corporations who want to look at a competitor's website in private, people around the world whose Internet connections are censored, and even governments and law enforcement.
In this session I'll try to balance technical explanations (how Tor works) with social and community explanations (who uses Tor and why). Tor is of course open source, but to us transparency means far more than a software license. I'll give some context for censorship circumvention, for surveillance, for onion services, for why a decentralized design is better for users, and then I will stick around for the rest of the conference to answer questions.
Sobre Roger Dingledine: Roger Dingledine is co-founder and original developer of the Tor Project, a nonprofit that develops free and open source software to protect people from tracking, censorship, and surveillance online. Roger works with journalists and activists on many continents to help them understand and defend against the threats they face, and he is a prominent researcher in the online anonymity field.

What does it mean to build software for humanity? Hear pioneers discuss their journeys creating open projects that became indispensable to billions: lightweight databases, anonymous communication, video standards, and beyond. This conversation goes beyond technology to explore the principles that unite them, and the unique challenges of leading when thousands of voices shape your vision. Hear from the architects of the open web on freedom, responsibility, and the future they're building together.

Since close to 20 years, he has been a key contributor to numerous open source projects, such as FFmpeg, x264, dav1d, VLC and a few others, which are powering most of the video streaming services. Active proponent of the open source ecosystem, he has also been the president of the VideoLAN foundation, since its foundation in 2008.
He is also the creator and leader of Kyber, a new open technology start-up made to control machines, drones and robots in real time.

Sobre Robin Bender Ginn: I lead global open technology ecosystems at the intersection of AI, developer platforms, and the critical infrastructure that powers them – shaping how technologies used by billions are built and run.
As Executive Director of the OpenJS Foundation and a former Microsoft executive, I've spent my career operating across industry, government, and open source developers to align stakeholders and drive system-level change. At Microsoft, I helped lead the company's transformation to open source and later drove AI strategy, commercialization, and industry-wide interoperability standards.
Today, I steward Node.js and the broader JavaScript ecosystem, the runtime and language powering 99% of the web, while focusing on the platforms, ecosystems, and economic models required to support AI and modern software at global scale.
