Wu Shuo learned that Ethereum co-founder Vitalik Buterin wrote about exploring the feasibility of constructing index-tracking assets using options instead of the CDP debt model. He believes this design can reduce dependence on real-time oracles and prevent large-scale liquidations during extreme market conditions, allowing asset exposure to deviate from the target index in a smoother manner. Vitalik stated that, compared to algorithmic stablecoins relying on real-time price feeds, he prefers to hold assets built on such a design.
