The Steem Dollar (aka Steem Based Dollar, Steem Backed Dollar or SBD) is a token that is meant to be worth about $1 USD, making its value much more stable compared to STEEM (see STEEM Tokens). To be a bit more technical, a Steem Dollar is a promise to pay one dollars worth of Steem when it's redeemed.

The benefit of Steem Dollars is that business can accept them more comfortably since they have a more stable value. Can you imagine being a shop owner and trying to sell your $50 product for STEEM which a couple months ago would have been for 500 Steem compared to today being less than 50. Pricing their products and services are much easier when using a stable value, as well as knowing that what they've already been paid, won't lose value.
