EDIT Btw: do I remeber this right, that alle the denomination fees go to the block rewards?
yep, all fees (except proposal preparation fee which is destroyed) go to block reward
Why is the proposal preparation fee destroyed? I imagine there's a good reason for it, but couldn't it go towards the block reward too?
Evan's response +
Another principle is that system should treat all proposal submitters equally i.e. this fee should also be equal for them. But a MN owner can see that his MN is going to be paid next ("masternode winners") so he could (potentially) try to prepare proposal (i.e. pay that fee) in the "right" block to "get a discount". Could be smth like this: block reward would be fee(5)+"normal block reward"(~6, according to
http://178.254.18.153/~pub/Darkcoin/masternode_payments_stats.html ) => reward will be ~11/2=~5.5 instead of normal ~6/2=~3 i.e. MN owner would get half of his proposal fee back (or get a 50% "discount" if you like). To avoid such situations and make process of submitting proposals more fair to everyone it's better to destroy proposal fee completely.
