The Ethereum Foundation is shifting its focus toward "true decentralized finance (DeFi)," prioritizing the development of permissionless, open-source systems that do not rely on centralized control points (such as admin keys or founders). Vitalik Buterin emphasized the vision of building a global private financial system that prioritizes security and gives users direct control, noting that protocols must pass a "detachment test" to operate independently of their creators. This move aims to strengthen decentralization, privacy protection, and technical standards within the ecosystem.
