I have the whitepaper on my TODO list so I'm not totally across it. I know that some of the senior members of #steemsilvergold are pretty keen on it. If you ask a guy like @thedamus about it he'll probably tell you he is "balls deep" (his words, not mine :p)
It's probably a good one for me to bump up the TODO list today considering I've just shifted my reserves from SBD to Bitcoin and I need somewhere to keep my reserves safe while this latest market volatility plays out.
