Ethereum co-founder Vitalik Buterin has proposed a radical architectural change for decentralized finance (DeFi) aiming to eradicate catastrophic flash liquidations. Through the Ethereum Research forum, Buterin suggested moving away from debt-based models, such as Collateralized Debt Positions (CDPs), and adopting options-based synthetic assets instead, transforming risk management within the ecosystem.
The core of this proposal lies in eliminating the dangerous dependency on real-time price oracles, which are highly vulnerable to manipulation and flash loan attacks. In Buterin’s new design, sudden and global liquidations are replaced by the issuance of token pairs with predefined strike prices and maturity dates, allowing users’ financial exposure to change smoothly and predictably.
In the long term, this approach aims to allow users to rebalance their positions slowly over days instead of seconds, prioritizing capital preservation over absolute, real-time stability. The next step for the DeFi community will be to evaluate the feasibility of implementing these specialized market structures to mitigate systemic risks.
