PANews reported on February 14 that Ethereum co-founder Vitalik Buterin published his latest article "Why the L1 Gas Limit Needs to Be Increased Even in L2-Dominated Ethereum". The article stated that an important recent discussion in the Ethereum roadmap is about how to increase the L1 gas limit. Recently, the L1 gas limit increased from 30 million to 36 million, a 20% increase in capacity. Many people support further substantial increases in the near future. These increases are safe because of recent and upcoming technical improvements: improved efficiency of Ethereum clients, reduced need to store old history due to EIP-4444 (see roadmap), and future stateless clients. However, before we go down this path, it is important to ask a question: In the context of a Rollup-centric roadmap, is raising the L1 gas limit the right thing to do in the long run? We don't want to end up facing the centralization risks brought about by high L1 usage without really being sure that we will benefit from it. This article argues that even in a world where most uses and applications are on L2, significantly expanding L1 is still valuable because it enables a simpler and safer application development model. The article concludes that even in an L2-dominated world, a ~10x expansion of L1 gas has significant value. This in turn means that the short-term L1 expansion that can be achieved in the next 1-2 years is valuable regardless of the long-term situation.
