The goal pursued by QSD is the continuous growth of QSD issuance and the intrinsic value of CEC. For this goal, the system will set up a mitigation mechanism for the CEC minted at the time of redemption and recollateralization in the early stage of the system to avoid large fluctuations in the price of CEC tokens. Specifically, when redeeming or recollateralizing, the value of CEC tokens in the algorithm part will be converted to CBT. When certain conditions are met, users can convert CBT to CEC one-to-one.
