Arti: Rewriting Tor in Rust

2026-10-28 Arti, Security, and Tor.

Lecture during Copenhagen Rust Community, at Google Denmark, in Copenhagen, Denmark.

This presentation was focused on The Tor Project’s effort to implement a from-scratch implementation of the Tor protocol in Rust called Arti. The presentation went over the various historical events that led to the decisions that brought us to where we are today. Arti is now a key focus within the organization, multiple teams are investigating using Rust for their software development needs, and we are working with external parties on adoption of Arti to provide anonymity and later anti-censorship for their applications.

The presentation took place at Google Denmark as part of the Rust Copenhagen Community’s monthly meetup series.
