According to BlockBeats, on September 22, Ethereum co-founder Vitalik Buterin responded to Bankless founder David Hoffman’s discussion on the social platform that “the rollup-centric roadmap has been “completed”, and the primary optimization focus in the future will be L1″. He said, “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 ‘the rollup-centric roadmap is complete’ is a premature declaration of victory.
We are only 1.3x usage peak away from blob full (= 21600 blobs/day). We need to launch peerdas and start scaling safely alongside L1 improvements.”
Hoffman continued: “If we increase blocktimes on L1, won’t that also increase the supply of blobspace? Focusing on L1 feels synergistic with focusing on both L1 and L2, while focusing on DA only benefits L2.”
Vitalik explained: “If we reduce the slot time without changing other variables, then the answer is yes. But the limits of both are determined by bandwidth limits, so if we are happy with today’s gas/blob limits, then we will also be happy with the gas/blob limits directly.
So I generally think of bandwidth and latency as two separate 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.”
