Hi, At a bitcoin meetup in Oct 2015, @eduffield mentioned that PrivateSend would use a "protocol based" solution in evolution, as opposed to MN mixing. At the same meeting it was mentioned that documentation describing this approach would be made available in the following months. I appreciate the core team is very busy on 12.1 right now, but is there any indication of when we might see a more detailed description? Also, is this related to the "credits" system mentioned on the bitcoin bus, or is that something different? Thanks in advance. H.
