Ethereum co-founder Vitalik Buterin stated on the X platform that the Ethereum ecosystem urgently needs a more mature decentralized stablecoin system, pointing out three core issues: first, a value index superior to that pegged to the US dollar should be built; second, a decentralized oracle design that cannot be captured by large funds is needed; and third, the competitive relationship between staking rewards and stablecoins/CDP mechanisms needs to be resolved. At the same time, Vitalik believes that pegging to the US dollar is acceptable in the short term, but in the long term, reliance on a single fiat currency system should be reduced to enhance system resilience.
