Wu Shuo learned that Vitalik Buterin stated DeFi is an important component of Ethereum's core value. The Ethereum Foundation (EF) will focus on supporting a global financial system that is permissionless, open-source, privacy-first, security-first, decentralized, enhances user asset control, and reduces centralization risks, rather than indiscriminately supporting "on-chain finance." He pointed out that future DeFi should not only improve superficial products like stablecoins but also conduct systematic innovation around fundamental issues such as risk management and future expenditure hedging. Additionally, protocols should have the "walkaway test" capability, meaning they can continue to operate sustainably even if the original team disappears or fails. EF's key directions include improving security through audits and standards, introducing AI-assisted formal verification and user-side proxy enhancements for protection, strengthening oracle security and decentralization, promoting privacy payments and privacy in complex financial scenarios, and improving DeFi's open-source licensing and forkability.
