What is difference from Monero? Only block reward and blocktime?
Yes only block reward and blocktime.
But most development is done on the Monero or Boolberry code (pool bounty's, QT wallet etc.)
ps.
I'm not here to spread fud but the dev here says Monero is instamined and had shifts in the emission. let me tell you, that was absolutly not true! (it was discussed but nothing was changed on this) i started mining Monero 2 hours after release when it was around block height 100, they even delayed the launch untill proper windows binaries where released! Please dev, play it fair and dont spread fud!!
At the same time I paid some attention to the alternative realization of the protocol - it was BitMonero / Monero. But I had doubts: from the very beginning it had some unpleasant and outrageous stories attached - like those ones with the main coin developer, with the shifts in the emission curve, with instamine and with the unavailability of optimized files for all users.
