The program provides researchers with a four-month scholarship to advance Ethereum technology, including From client implementation, testing and specification, to participating in the latest core protocol research. The fourth batch of EPF runs from July 2023 to November 2023, culminating in a live event at Devconnect in Istanbul. EPF is an initiative designed to support the development of the Ethereum core protocol by providing a means for protocol contributors to make meaningful contributions. The program is tailored for developers and researchers interested in Ethereum, its community, and decentralized technologies.
