Jinse Finance reports that Optimism has announced on the X platform that applications for Retro Funding 5 projects are now open. This project aims to provide financial support to encourage and recognize individuals and teams who have made significant contributions to the Ethereum ecosystem. Previously, the registration phase for Retro Funding 5 of OP Stack had been launched, with plans to allocate 8 million OP tokens to contributors in several categories: first, technical experts including Ethereum core developers; second, developers involved in the research and development of OP Stack technology; and finally, developers who have contributed to the development of OP Stack tools. This initiative not only reflects Optimism's emphasis on community building but also provides strong support for promoting the sustained prosperity and development of the Ethereum ecosystem.
