Spark Community has released a proposal to adjust the SubDAO proxy management mechanism. According to Foresight News, the proposal suggests several changes to the SubDAO proxy reserve plan. These include reducing the risk capital requirement (RRC) look-back period from 12 months to 3 months, lowering the Spark product guarantee from 5 million USDS to 1 million USDS, and shortening the target operating cycle from 24 months to 12 months. Additionally, the standard buyback rate is proposed to increase from 10% to 25%. A new parameter, 'buyback recipient,' is introduced to specify the direction of SPK tokens purchased by the buyback executor.
