In the last few years, we've seen more and more interest in Tor onion services (aka Tor hidden services). They are used by press to host whistleblowing platforms, by activists who want to set up a website that authorities want to shut down, by service providers to offer more security to their users, and for tons of other uses as well. This panel will be presenting the technical aspects of Tor onion services as well as interesting use cases. As the onion service protocol aged, weaknesses started to appear in its design. For this reason, the speakers have been working since 2013 on the next generation onion service protocol. You'll get a status update on their progress, an explanation of the improvements it brings, and also why it is greatly needed.
