Vitalik: "Reducing L1 slot time" is worth discussing, but it should be done cautiously to avoid harming independent stakers
ChainCatcher news, Bankless founder David Hoffman posted on X that, in a sense, the rollup-centric roadmap is already "complete," with current progress including the launch of 4844, DA, and cheap L2, while the primary optimization focus for the future is L1.Vitalik Buterin responded, saying: "I don't think this is a priority issue. The next step for DA is peerdas, and the people working on this are almost completely disconnected from those working on SSF or EVM execution improvements. I do think that saying 'the rollup-centric roadmap is complete' is declaring victory too early. We are only 1.3 times the peak usage away from blob full data (= 21600 blobs/day). We need to kick off peerdas and start secure scaling while improving L1." Hoffman continued, stating: "If we increase the block times of L1, won't that also increase the supply of block space (blobspace)? Focusing on L1 and simultaneously focusing on L1 as well as L2 feels synergistic, while focusing on DA only benefits L2."Vitalik explained: "If we reduce slot time without changing other variables, then the answer is yes. But the limits of both are determined by bandwidth constraints, so if we are satisfied with today's gas/blob limits, then we will also be directly satisfied with the gas/blob limits. So I generally think of bandwidth and latency as two independent issues. I do think reducing L1 slot time is worth discussing, although this needs to be done carefully to avoid 'killing' independent stakers, or even geographically dispersed stakers."
