Optimism, an Ethereum Layer 2 network, has started to distribute 15 million OP rewards to Ethereum core developers and educators through its "Retro Funding" initiative, which aims to "reward those who have made significant contributions to Ethereum." The distribution is still in its early stages, but Optimism has already distributed a significant portion of the rewards to well-known Ethereum core developers, including Vitalik Buterin, Gavin Wood, and Hudson Jameson. Optimism's Retro Funding initiative is a unique way to recognize and reward the contributions of those who have helped to build and maintain the Ethereum ecosystem. By providing financial support to these individuals, Optimism is helping to ensure that the Ethereum ecosystem continues to thrive and grow. In addition to core developers, Optimism is also distributing OP rewards to educators who are helping to spread the word about Ethereum and its benefits. This includes individuals who are creating educational content, teaching classes, and hosting workshops. The Retro Funding initiative is a key part of Optimism's mission to make Ethereum more accessible and user-friendly. By rewarding those who are contributing to the Ethereum ecosystem, Optimism is helping to create a more vibrant and sustainable community.
