According to Foresight News, Venus Protocol, a lending protocol on BNB Chain, has released the Venus V4 white paper. The new version improves risk management, decentralization, and user experience. In terms of risk management, Venus V4 introduces isolated pools, which aims to address the shortcomings of building protocols with a single liquidity pool and increase scalability for the largest liquidity protocol on BNB Chain. Venus isolates the risk of assets from the core pool of the protocol; introduces an isolated environment for assets that are much less volatile than traditional cryptocurrency assets, rather than being too volatile; by introducing new pools, the risk management and functionality of each pool can be thematically customized for any given asset class or profile.

The isolated pool system is based on the PoolRegistry contract. It maintains a directory of independent lending pools, allows the creation and registration of new pools, and provides getter methods to obtain pool details. To add new markets to existing lending pools, PoolRegistry deploys JumpRateModelV2 or WhitePaperInterestRateModel contracts, deploying upgradeable VTokens for the market before obtaining approval from the market comptroller.
