Not really. It's just a way of measuring value more removed from any one nation's currency. You take the price, in DAI, of a bunch of historically stable priced goods. Bread, tires, shoes, etc. Measure the averaged normalized variance in price over time for these goods in DAI. Then tune the economic incentives to make those variances stay at as close to zero as possible.
