Vitalik Buterin, one of the creators of Ethereum, is suggesting a big change for the world of decentralized finance (DeFi). He believes DeFi should move away from relying on loans and collateral – like the systems currently used with Collateralized Debt Positions (CDPs) – and instead focus on using options to create synthetic assets.
A new proposal suggests a way to prevent the sudden and severe liquidations that have often harmed users of decentralized finance (DeFi) during times of rapid market changes. It was published on the Ethereum Research forum.
The flaw of real-time oracles
Many existing DeFi systems that create things like algorithmic stablecoins depend a lot on borrowing and automatic selling of assets. If the value of a user’s deposited assets falls too low, the system automatically sells them off to protect itself from losing money.
Death to Liquidations: Vitalik Pitches Options-Based DeFi
Buterin argues this system relies too much on current price feeds, which are easily exploited and susceptible to attacks like flash loans.
As a crypto investor, I’ve been looking into oracles, and honestly, building secure ones is *tough*. The best way to get a reliable and affordable oracle seems to be layering things: use a prediction market to verify the data coming from a more secure, but pricier, oracle. Basically, only rely on the expensive oracle when the prediction market flags a potential problem – a disagreement. It’s a bit complex, but it feels like the most solid approach.
How options-based DeFi works
Vitalik Buterin’s latest design eliminates the need for liquidation. Rather than borrowing money, users create token pairs by securely locking up assets like Ethereum. These tokens function similarly to standard financial options, having a predetermined price (S) and an expiration date (M).
As an analyst, I’ve observed that our system avoids those jarring, all-or-nothing liquidations you sometimes see in other markets. Instead, a user’s risk exposure adjusts gradually and in a way that’s easy to anticipate, even during significant price swings.
Vitalik Buterin proposes creating specialized systems for trading that cater to users who don’t need immediate results. These systems would allow them to gradually adjust their investments over days instead of needing to react within seconds.
A trade-off worth making?
While this design isn’t perfectly suited to be a traditional “stablecoin” due to small yearly fluctuations (between 1% and 4%), Vitalik Buterin believes the increased security it offers is a good trade-off for users more concerned with protecting their money over time than with having absolutely consistent, immediate value.
Buterin finished by saying he’d be much more comfortable storing data on a system like this one, rather than relying on a system that needs instant, up-to-the-minute information from an external source.
