One way we help human rights defenders and organizations take back their right to privacy online is by helping them to use and set up onion services. Last year, thanks to the support of Digital Defenders Partnership, we wrote a series of Onion Guides intended to make it easier for our partners to correctly and safely set up their own onion services.
In our last article, published in RIPE's website, we described the work that happened in 2020 related to giving IPv6 support to the Tor network. Tor 0.4.5.1-alpha is the first release that includes all the work described in the RIPE article. Relays running 0.4.5.1-alpha are the first to report IPv6 bandwidth statistics.
The biggest change introduced thanks to this project is a generic publish-subscribe mechanism for delivering messages internally. It is meant to help us improve the modularity of our code by avoiding direct coupling between modules that don't actually need to invoke one another.
What alternative protocol architectures and route selection protocols would offer acceptable gains in Tor performance? Would they preserve Tor properties? Is it possible to improve Tor performance without changing protocols? Is it truly possible to deploy Tor at scale? And what would the full integration of Tor and Firefox look like? Those are some of the questions that Mozilla is calling researchers to answer in the privacy & security part of their Mozilla Research Grants program.
As technology shapes many parts of our lives, we believe it needs to be built in a way that makes the world a better place. For this, we need everybody’s voice and perspective when making technical and political decisions at Tor.
