Bankless founder David Hoffman wrote on X that, in a sense, the rollup-centric roadmap has been "completed". Current progress includes the launch of 4844, DA, and cheap L2. The primary optimization focus in the future will be L1.

Vitalik Buterin responded: “I don’t think it’s a priority issue. The next step for DA is peerdas, and the people working on that are almost completely disconnected from the people working on SSF or EVM execution improvements.

I do think it’s a premature declaration of victory that ‘the rollup-centric roadmap is complete’. We are only 1.3x usage peak away from full blobs (= 21,600 blobs/day). We need to launch peerdas and start scaling safely in parallel with 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, whereas 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.” #DYOR42711
