Steem Dollar (SMD) operations:
- SMD rewards: A percentage of SMD value is created at an APR set by the witnesses and paid to SMD holders as SMD
- Feed Rate following: The amount of STEEM for which the total SMD in existence can be redeemed will change based on changes in the price feed. This change is effectively destruction ("burning") of STEEM when the value of STEEM (as measured by the feed) is increasing, or creation of STEEM when the value of STEEM (as measured by the feed) is declining.
