Stardust is linked to purchases in the shop. You will get 100 STARDUST for every 1 STEEM you spend in the shop. You can find your Stardust in your wallet.
(soon) You have the chance to find small quantities of stardust while exploring deep space. This makes explorations much more valuable. If exploration wasn't successful and your explorer returns safely, i.e. has not been lost, you have the chance to get stardust.
