Some of you may have noticed experience points on the ranking page.

Those points will come into play when research and missions finally gets implimented. You may need a minimum number of experience points before you can reresearch certain items. Same thing for being able to do things on some missions.

Right now you gain and lose experience upon things like trading, attacking, and losing things.

More things will be added to cause you to lose and gain experience points in the future. So the more active you are in the game the more experience you gain.
