Twin goals of EF:

1. Usage of Ethereum - but usage of a type where users are actually benefiting from Ethereum's underlying properties
2. Resilience and decentralization of Ethereum - viewed holistically, focused on addressing points of weakness anywhere in the stack

Focusing on both the practical usage and the robustness of Ethereum is crucial for its long-term success. Striking a balance between utility for users and maintaining decentralization will be key in achieving these twin goals effectively.
