Establish a guarantee mechanism and positive feedback liquidity rewards in the deflation phase

YIP Title Goes Here

Basic Summary
In each adjustment, part of the funds in the Treasury is used as the liquidity reward. Meanwhile, the liquidity reward is the longer the mortgage period is and in the deflation stage (similar to the Empty set dollar), the reward is doubled.

The concept is to avoid yam’s death spiral and establish a positive feedback mechanism to reduce price volatility during the deflationary period.

Just like ESD has established a deflationary protection mechanism, I recognize that yam’s treasury can do something in this part, and at the same time, unlike amp’s liquidity reward, it will be used up for a day.

This sounds like it needs more thought. I recommend posting in the Proposal Brainstorming category. Locking for now.
