I've written up a post about this on reddit, so I'll refer you to that

The TL;DR is that you can mine while proving knowledge of the transactions that you are mining to get a 5% higher reward. As wolf0 pointed out, though, no miners currently support mining with PoK on (except for the CPU QT wallet miner, which is really slow).

Thanks for watching this thread.
As far as I know your post on reddit seems to explain how the wallet POK operates.
Some gpu miner dev's told me that its not helping as much for getting an external (gpu)miner working with POK.
There are some more nuts to crack. I wrote you yesterday a reddit msg about this point (have on reddit a different username - cheers
