The novel insight uses market forces itself to see how much of a QSD can be algorithmically stabilized with the CEC token so that it keeps a tight band around the target price. Purely algorithmic/rebase designs like Basis, ESD, and Seigniorage Shares have wildly fluctuating prices as much as 40% around $1 that take days/weeks to stabilize before going through another cycle. This is counterproductive and arising the assumes whether the market actually needs a stablecoin with 0% collateralization. From the perspective of stablecoin design, this high volatility of purely algorithmic stablecoins is counterproductive and is not conducive to its final widespread promotion and combination with other DeFi applications. QSD doesn't make this ideal assumption. Instead, it measures the market's preference. It finds the actual collateral ratio which holds a stablecoin tightly around $1, periodically testing small differences in the ratio when the price of QSD slightly rises/drops. QSD uses AMM concepts to make a real-time fractional-algorithmic stablecoin that is as fast at price recovery as Uniswap and Balancer, keeping trading pools correctly priced.
