In Securely hosting a Tor hidden service/site, everyone concludes that the best approach is to host the server on a VM with Whonix and full-disk encryption. Thus, the server will be isolated, and if someone manages to get in, they will not be able to reveal your real IP.
I'd like to host a hidden site using a Raspberry Pi, but as far as I know, they have ARM processors and cannot run VirtualBox, for instance. Plus, the system resources of a single board computer are quite limited. On the other hand, I don't want to have my laptop turned on 24/7.
What is the best approach when it comes to hosting a Tor hidden site using a Raspberry Pi?
