The TOR project has announced a new generation of Onion services. The project has been ongoing for four years and just released its alpha version. See here for the changes and how to try out the new system.
The new version is intended to improve the security of onion services. It features new crypto algorithms and a new protocol. These changes are intended to prevent data leakage and reduce the attack surface.
The project is looking for coders and testers so if you want to be part of this, follow the link to find out how you can help. If you’re not a coder but still want to help, they also welcome donations.
