According to BlockBeats, on January 11, Vitalik Buterin expressed the need for improved decentralized stablecoins in the current crypto industry, identifying three main issues that require resolution.
Firstly, Buterin suggests finding a more suitable index to track than the U.S. dollar price. One of the visions for national-level resistance should be to reduce reliance on the dollar.
Secondly, he emphasizes the importance of designing decentralized oracles that cannot be controlled by large sums of money. If oracles can be bought by significant financial resources, protocols would need to extract high value to make attack costs exceed the protocol's market value as a defense mechanism.
Lastly, Buterin points out the challenge of competitive staking yields. If stablecoins cannot offer competitive returns, often lagging behind staking yields by several percentage points, they may struggle to attract funds in the long term.
