[Vitalik Proposes a DeFi Solution to Construct Index-Tracking Assets Using Options Instead of Debt] Deep Tide TechFlow reports that on June 1, Vitalik suggested considering the use of options, rather than collateralized debt positions and liquidation mechanisms, as the foundation for constructing index-tracking assets in DeFi. The core idea is that during periods of extreme price volatility, risk exposure would no longer trigger centralized liquidations but would instead deviate from the target index exposure in a smoother manner. Vitalik stated that one major advantage of this design is that it does not require real-time oracles and can operate based on 'slow oracles.' However, the downside is that it requires periodic rebalancing, and whether the rebalancing can sufficiently resist slippage remains an unresolved issue. He also mentioned that compared to solutions relying on real-time oracles, he would feel more comfortable holding algorithmic stablecoins within such a structure.
