STEEM blockchain already can handle tokens. In fact, @pocket-a by @biophil was the first token that was airdropped on Steemitians (one million per account). Anybody could send POCKET with a comment. It was initially traded at Bitshares 100-200 per BTS. It is not maintained anymore. It is open source and anybody can launch a TOKEN (similar to SMT) right now if one wishes.

SMT should not be that hard. It will be probably released but delayed.
