This is a MasterCoin feature that adds an extra layer of protection to those storing their wealth in digital currency. With savings addresses, MasterCoin has the ability to reverse transactions
When the value of the “commodity coin” goes too high, the currency’s escrow fund will start creating new commodity coins in exchange for MasterCoins. When the value is too low, it will trade MasterCoins in exchange for commodity coins, then destroy those coins. Through this control of supply and demand, a MasterCoin derived currency can sustain a balanced value.
What idiots! They are just re-inventing fiat. Regulated shitcoin "backed" by bitcoin, the same way as USD was "backed" by gold.
