I would eliminate PoS...
Yeah, i don't like PoS...
PoB on the other hand... that fix about offline burned coins affecting PoB minting difficulty, that needs to be done.
Slim, btw, was trying to include getrawtransaction on the code (i even forked it on github) but heck, most "getrawtransaction" implementations are totally incompatible with Slimcoin's code. I strongly suggest you take a look, i will try my hand at it again on the near future, but my current priority is to get my system up and running because servers need to get paid.
+1 to eliminate PoS. Its a nuisance.
