TechFlow News, June 1: Vitalik suggested considering the use of options—rather than collateralized debt positions and liquidation mechanisms—as the foundation for building index-tracking assets in DeFi. The core idea is that during periods of sharp price volatility, risk exposure would no longer trigger centralized liquidations but instead deviate from the target index exposure in a smoother manner.
Vitalik noted that a key advantage of this design is that it does not require real-time oracles and can operate using “slow oracles.” However, a drawback is the need for periodic rebalancing, and whether such rebalancing can sufficiently resist slippage remains an open question. He also stated that, compared to schemes relying on real-time oracles, he would feel more comfortable holding algorithmic stablecoins structured in this way.
