Vitalik Proposes Options-Based Synthetic Assets
Vitalik Buterin has proposed replacing DeFi's debt-and-liquidation model with an options-based system where each ETH is split into two paired tokens (P and N) that always sum to one ETH regardless of price movement, making it structurally impossible for any position to go bankrupt and eliminating the need for forced liquidations. The design also relaxes oracle requirements significantly. No position can be wiped out in real time, so the system can rely on slow-moving prediction-market-style oracles rather than near real-time price feeds, reducing the manipulation risk that plagues current DeFi protocols during volatile periods. The proposal remains theoretical and faces open questions around rebalancing costs and execution slippage, but it outlines a fundamentally different architecture for synthetic asset issuance.
