But they did the opposite. The onion is gone. Presumably they have some reason for that?
Also onion sites in general are very slow because of the six hops. I’d like an open source solution that can be used by anyone, including clearnet sites, so that use of captchas and browser probing can be reduced across the entire web.
And Trocador couldn’t go onion only because an increasing number of their partner exchanges were no longer willing to be available over .onion or i2p.
That might work, I will certainly look at it, but I like the idea of premining PoW tokens because it won’t bog your browser down at the time you need to go through, and the cost can also be made higher. It could be used as a general cost for things that need spam protection, such as creating accounts, making posts, submitting contact forms.
