Jesse Pollak, head of the Base protocol, said in a reply to Solana co-founder toly on X: "I don't think the Base<>Ethereum relationship is a zero-sum competition. Base and other L2s are actually executing the Ethereum roadmap, and many of us have been working on it together for more than 5 years. If Base develops, Ethereum will develop.
Will Ethereum's transaction acceptance rate on L2 be lower than L1? Yes, absolutely. Will this acceptance rate be like today when we are in the biggest growth opportunity in human history? I doubt it - I expect it will be higher, but it will still be lower than 100%. Should L1 also increase capacity? Yes, that's good too!
We can win together. Building with us is 100 times more interesting and 100 times more likely to succeed than tearing each other down and competing in a zero-sum way.
That being said, I do understand how useful it is for you to drive us to compete with each other. The more we compete, the less we can focus on working together across multiple levels to build the best possible version of Ethereum. My goal is to make sure that doesn't happen. Achieve each other, stick to the foundation, and keep building."
