The Ethereum Foundation has announced that the Ethereum Protocol Fellowship Cohort 7 (EPF7) is now open for applications, with a deadline of May 13th. This program aims to cultivate engineers capable of participating in the development of the Ethereum core protocol, focusing on core network attributes including censorship resistance, open source nature, privacy, and security. Key areas of focus include client implementation, protocol specification, testing, and cutting-edge research. This cohort of EPF7 will adopt a "small-scale, high-density" model, reducing the number of participants to enhance the depth of mentorship and the quality of project contributions, while strengthening collaboration opportunities with the core development team. The program will run from June to November. Selected participants will receive mentorship and support from the Ethereum core developer community, and some will also receive monthly grants to focus on protocol development. The program's goals include cultivating long-term contributors to the Ethereum core R&D team and driving participants to achieve substantial results in client development and protocol research. The EPF team will hold an online briefing on May 6th at 15:00 UTC to further explain the project details and answer application-related questions.
