I don't know who that is, I am the main dev for Qrk2. 

I forked the Quark github but ended up using RVN more then Quark.  The hashing algo is X16r from Ravencoin.

Once masternodes and POS 3.0 activate (I took from PIVX) after 8.4 million coins are mined then POW will be de-activated on the network and we will be pure POS coin.

Qrk2 transactions will be untraceable once masternodes activate.
