I want to host a hidden service forum using whonix for added security, however earlier I was reading the tor project blogs and I came across next generation hidden services
Should work no problem, Whonix does not make modifications to Tor itself for a host of reasons. However, please mind the bugs: The Tor Project / Organization · GitLab
Not by default. v3 onions require Tor 0.3.2 or higher (which is currently in alpha-testing). The latest stable series (included in Whonix 13 & 14) is 0.3.1. If you want to test, you can install the experimental version from Tor Project’s repo: How can we help? | Tor Project | Support
Would I need to install tor alpha on both gateway and workstation?
I must also note this is not going to be a live forum anymore now due to this version of tor is still alpha state, It will be tested on my home machine only.
Gateway only. Workstation tor is skipped over by anon-ws-disable-stacked-tor package.
v3 onions are a big deal in the evolution of Tor. Would be great if you could test and report back. You may be the first - so no guarantees that it’ll even work.
