There is only a light paper on SPKnetwork. There will probably end up being a white paper as the technicalities of the code are built out.
We look forward to building it. If it goes well, it will change a lot of the grounds for the frustration in this post thread
I meant in general, theres tons of whitepapers/bluepapers/lightpapers out there for tons of projects and I try to read a bunch :) Time constraints! heh
