Ok that wasn't a good explanation.
Let's say John doe sends 1000 2give to Jane doe the tx fee is 1%. So the block reward for that block is now 100 2give. Let's say there is 100 nodes open all 100 will be competing for that and if YOUR wallet processes that block you get the 100. A faster PC or processor doesn't give you any advantages with this coin and there is no set block reward.
