According to Planet Daily, Venus Protocol, a lending protocol on BNB Chain, has released the Venus V4 white paper, focusing on improving risk management, decentralization and user experience.
Among them, in terms of risk management, Venus V4 launches isolated pools to safely introduce long-tail assets, aiming to address the shortcomings of building protocols with a single liquidity pool. Isolated pools consist of a collection of asset separations with custom risk management configurations, providing greater diversity for managing risks and lending. Isolated pools can isolate hypothetical failures, preventing them from spreading to unrelated markets and affecting the risk status of the entire protocol. In addition, isolated pool rewards can customize each asset in each pool to provide users with tailored liquidity incentives.
The isolated pool system is based on the PoolRegistry contract, which maintains a directory of independent lending pools, allows the creation and registration of new pools, adds new markets to existing pools, updates pool metadata, and provides getter methods to obtain pool details. To create a new lending pool, PoolRegistry deploys a pool proxy and sets the Comptroller implementation address to the proxy. After setting up the Comptroller, it adds the pool to the pool directory.
To add a new market to any existing lending pool, PoolRegistry deploys a JumpRateModelV2 or q contract as the interest rate model using the relevant factory, and then deploys an upgradeable VToken for the market before gaining support from the market’s Comptroller.
