Vitalik proposes replacing liquidation mechanisms with options, exploring new DeFi and algorithmic stablecoin architectures

Ethereum co-founder Vitalik Buterin proposed a DeFi design based on options rather than collateralized debt positions (CDPs) and liquidations on EthResearch. This model tracks asset indices through an options structure, preventing users from facing immediate liquidations during extreme market volatility, instead allowing for a smoother, non-linear deviation from target exposure. Vitalik believes a significant advantage of this proposal is its independence from real-time price oracles, instead operating on "slow oracles" similar to those used in prediction markets, thereby reducing oracle manipulation risks. He stated that he would be more inclined to hold algorithmic stablecoins built on such mechanisms compared to those relying on real-time price updates. However, the design still faces challenges with periodic rebalancing, particularly how to reduce slippage costs during this process remains an unresolved issue. Furthermore, Vitalik also cited previous viewpoints, suggesting that in the long term, reliance on a single fiat currency for stability could be gradually weakened, shifting towards individuals or institutions achieving value stability through self-configured customized baskets.
