Ethereum's Vitalik Buterin is rethinking how DeFi handles market crashes
Vitalik Buterin proposed replacing much of DeFi’s debt-based design with options-based structures for crypto index products and potentially algorithmic stablecoins. Instead of relying on collateralized debt positions that can trigger sudden liquidations during volatility, users would hold exposure that gradually shifts away from a target allocation as prices move. He argued this could reduce cascading forced sales, improve resilience, and allow protocols to use slower, less manipulation-prone price oracles. He said this model could be safer than systems dependent on real-time oracle updates. The main downside is that it would require periodic rebalancing, and it is unclear whether the trading costs and slippage would be practical. The idea is still theoretical and not yet implemented.
