Vitalik Buterin, co-founder of Ethereum, praised Optimism, a Layer-2 blockchain network built on Ethereum, for its commitment to funding public goods. Buterin commended Optimism's Retroactive Public Goods Funding (RetroPGF) initiative, which distributed 30 million OP tokens worth over $100 million to developers and contributors who played a role in building public goods underpinning the Optimism Collective. RetroPGF is an alternative funding source for public goods creators who struggle to raise capital from traditional channels. Despite Buterin's comments, the Optimism token did not see a significant increase in interest, while Ethereum's prices surged over 17% in the last seven days.
