According to a recent share from Josh Stark, a member of ETHGlobal, discussions about the spending structure of the Ethereum Foundation have attracted significant attention. To provide a deeper understanding, the foundation is preparing a detailed report covering financial activities in 2022 and 2023. Preliminary data from this report shows that the foundation's expenditures can be roughly divided into two major categories: internal and external expenses. Internal expenses account for approximately 38% of the total, while external expenses make up about 62%. This ratio reveals the foundation's support for its internal research and development teams as well as its generous investment in external collaborative projects. Specifically, internal expenses are mainly used to support several key projects and teams, including but not limited to:- Geth: The core client for Ethereum, responsible for implementing the network protocol.- Privacy and Scaling Exploration (PSE): Focused on enhancing privacy protection and scalability of the Ethereum network.- Solidity: As the language for Ethereum smart contracts, its development and optimization are crucial for the entire ecosystem.- Cryptographic Research: Ensuring the security and stability of blockchain technology.- Robust Incentive Group: Promoting community participation and development.- Devcon: A global developer conference aimed at fostering technical exchange and innovation.All these projects and teams maintain transparency through their activity details and progress shared via the official website, GitHub platform, and social media channels.
