Right now, the blockchain allows you to convert each SBD for $1.00 worth of Steem. This creates arbitrage opportunities when the price of SBD falls below $1.00, and this profit motive drives the price of SBD back up to $1.00. However, there has never been a similar downward pressure on the price when SBD is trading above $1.00. This is a one-way peg.
If we changed the blockchain code to allow people to convert a dollar's worth of Steem into 1 SBD, that would also create an arbitrage opportunity. When the price of SBD exceeded $1.00, people would convert their Steem into SBD and sell the SBD. This would create downward pressure on the price. When you add this element, it turns into a 2-way peg, which should do a much better job of keeping the SBD price around $1.00.
@tabgerinetravels what is 2 way peg
