More and more vendors are setting up shop on OpenBazaar 2.0, and now we have a fair amount of guides to install OB on Whonix to shop anonymously. However, while OB has the potential of becoming the ultimate DNM (no exit scams due to its decentralized nature, future Monero implementation will allow for private transactions), not a whole lot of people use Whonix, at least not properly (please, don't run it on Windows/OSX).
A guide to install OpenBazaar on Tails has been promised for a while now, but so far no contenders. I'm not tech savvy enough to even begin trying to make it work. Is anyone here even trying? How are you coming along? Anything other redditors here could help you with? Let's make this work as soon as possible, this is the major shift in DNMs we were waiting to happen!
One of the good things about using OB on Whonix is the protection from IP leaks, the OB software is fairly new and to trust your anonymity to it exclusively might not be a great idea IMO.
