Ethereum co-founder Vitalik Buterin has proposed a radical architectural shift for decentralized finance (DeFi), suggesting that the ecosystem move away from debt-based models like Collateralized Debt Positions (CDPs) in favor of options-based synthetic assets.
The proposal, published on the Ethereum Research forum, aims to eliminate the catastrophic "flash liquidation" events that have historically plagued DeFi users during high-volatility market crashes.
The flaw of real-time oracles
In current DeFi protocols, synthetic assets, such as algorithmic stablecoins, rely heavily on debt and automated liquidations. If the value of a user's collateral drops below a specific threshold, the system force-liquidates the position to prevent protocol insolvency.

How options-based DeFi works
Buterin’s new design completely removes the concept of liquidation. Instead of borrowing against debt, users mint token pairs by locking up a trustless asset like ETH. These tokens act exactly like traditional financial options with a set strike price (S) and a maturity date (M).
Instead of a sudden, global "you get liquidated" shock during sharp market moves, a user’s financial exposure changes smoothly and predictably.

A trade-off worth making?
This design might not serve well as a precise "accounting stablecoin" due to minor annual deviations (1−4%), Buterin argues that the security trade-off is highly favorable for users prioritizing long-term capital preservation over absolute, real-time stability.
"I would feel much safer holding algostables inside something like this," Buterin concluded, "than in something that depends on an oracle that has to give real-time answers."
