I'm not sure if they're actually using the STEEM blockchain to run on or not. I think they've at least partially divorced themselves from it to make the game faster, although you can still trade Future <--> Steem from within the game, so they have to have some links to it.

Getting raided daily isn't a thing anymore (that's one change this update helped remedy). The larger storage capacity and new base system has, for the time being, slowed the game significantly. If you're interested in coming back for a while, you could always join our gang, and I can send some soldiers your way to keep you protected while you build up (that's a new feature now as well, which I forgot to mention). :)

Come back to us, @slobberchops! We love you! :D
