Vitalik: It is worth considering and trying to build index-tracking assets based on options rather than debt

Vitalik posted on platform X, stating that building index-tracking assets based on options rather than debt is worth considering and trying, using options as the foundation of DeFi instead of CDPs and liquidation mechanisms. This design can avoid the extreme price fluctuations that cause severe and global liquidation effects, allowing exposure to the index to deviate from preferred exposure in a smoother secondary manner.

Its key advantage is that it does not require instant oracles and can operate based on slow oracles, which are the types of oracles used in prediction markets. The design has a clear drawback, which is the need for regular rebalancing, and it remains to be clarified whether and how rebalancing can have sufficient slippage resistance.

Vitalik added that compared to relying on oracles that must provide real-time answers and may be induced to give incorrect real-time answers without human remediation time, he believes that holding algorithmic stablecoins placed within such mechanisms is safer.
