The new mechanisms proposed by the Spark community represent a significant reform in the existing SubDAO proxy system, aiming to enhance governance and risk management efficiency through the phased adjustment of key parameters. The changes include reducing the operational cycle from 24 to 12 months, shortening the risk capital requirement review period, lowering collateral requirements, and introducing a new "buyback recipient" mechanism to improve transparency and liquidity management. Overall, these reforms enhance the adaptability and sustainability of the Spark ecosystem.
