Today, we are officially introducing a proof-of-work (PoW) defense for onion services designed to prioritize verified network traffic as a deterrent against denial of service (DoS) attacks with the release of Tor 0.4.8.
We realized Onion Services were not used to their fullest extent, so we launched support initiatives and resources to provide education, information and increase adoption.
With the deprecation of V2 onion services right around the corner, it is a good time to talk about V3 onion services. This post will discuss the most important privacy improvements provided by V3 onion services as well as their limitations. Aware of those limitations, our research group at the Institute of Network and Security at JKU Linz conducted an experiment that extracts information about how V3 onion services are being used from the Tor network.
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.
We are happy to share the news of another important milestone for .onion services! You can now get DV certificates for your v3 onion site using HARICA, a Root CA Operator founded by Academic Network (GUnet), a civil society nonprofit from Greece.
As you might have heard, some onion services have been experiencing issues with denial-of-service (DoS) attacks over the past few years. In this post, we would like to present you with two options that we believe can provide a long-term defense to the problem while maintaining the usability and security of onion services.
Starting today, July 8th, the Tor Project is running a one month campaign called #MoreOnionsPorfavor to raise awareness about onion sites, that is, websites available over onion services. We recently released a feature called Onion-Location in Tor Browser that announces to users if a website has an onion site available. Join us to make a more secure web! To participate, enable Onion-Location, share your onion site using the hashtag #MoreOnionsPorFavor on your favorite social media, and we'll select some onion service operators to receive a Tor swag. See below for all the details.
