The Ethereum Foundation has made it clear that DeFi should return to its hardcore decentralized roots, focusing on permissionless, open-source, privacy, and security to achieve global financial autonomy. It calls for resisting pseudo-decentralized variants and emphasizes that protocols must pass the 'abandonment test' (i.e., they can still operate even if the team disappears). The future focus will be on deep technological innovation (such as AI verification, privacy payments, and liquidation-resistant mechanisms) to build a financial system that is safer, more transparent than traditional finance, and lasts longer than its development teams. In Ethereum's DeFi Lego matrix, LINK (Chainlink) and UNI (Uniswap) are not just cornerstones but also the foundational infrastructure supporting the entire ecosystem. If DeFi is code that runs automatically, LINK is the only industry-standard data source ensuring that this code is not misled, providing external data and serving as the safety prerequisite for DeFi protocols to survive. Uniswap has defined the paradigm of modern decentralized trading, serving as the starting point for all on-chain economic activities. By enabling asset exchange, it acts as the economic engine that powers the DeFi ecosystem.
