Wu said that he learned that Bankless founder David Hoffman tweeted that the rollup-centered roadmap has been "basically completed" and that current progress includes proposal 4844, data availability (DA), and low-cost L2 solutions. In the future, optimization should focus on L1. In response, Vitalik Buterin replied: “This is not a priority issue. The next step for DA is peerdas, which does not overlap with the developer group performing improvements to SSF or EVM. It is too early to say that the ‘rollup-centric roadmap is complete’. Our current usage peak is close to 1.3 times the blob’s full data. We need to start peerdas and achieve secure expansion while improving L1.” Hoffman responded: “Wouldn’t increasing the block time of L1 also increase the supply of blob space? Focusing on L1 and focusing on L1 and L2 at the same time are synergistic, while focusing on DA is only beneficial to L2.” Vitalik explained: “If the slot time is reduced without changing other parameters, the answer is yes. But the limit of block capacity is determined by bandwidth. If you are satisfied with the current gas/blob limit, then reducing the slot time is worth exploring, but avoid adverse effects on widely distributed independent stakers.”
