Vitalik: The industry needs better decentralized stablecoins, and there are still three issues to be addressed

Vitalik stated that the current cryptocurrency industry requires better decentralized stablecoins, and there are still three problems to solve: - Ideally, a more suitable tracking index than the US dollar price should be found: one of the visions of national-level resistance is to reduce dependence on the US dollar price. - Decentralized and tamper-proof oracle design: if oracles can be bought out by large funds, to defend against attacks, protocols can only make attack costs higher than the protocol's market value through high-value extraction. - Addressing staking yield competition issues: if stablecoins cannot offer competitive yields (currently lagging behind staking yields by a few percentage points), it will be difficult to attract funds in the long term.
