Vitalik Buterin: "It's Too Early to Declare Victory on the Rollup-Centric Roadmap"

In response to Bankless founder David Hoffman's suggestion that the "rollup-centric roadmap is complete" and that the future priority should be L1 optimization, Ethereum co-founder Vitalik Buterin stated on X (formerly Twitter), "I don't think this is a priority issue. The next step for DA is peerdas, and the people working on that are almost entirely disconnected from those working on SSF or EVM execution improvements. I do think 'rollup-centric roadmap is complete' is declaring victory too early.

We are only 1.3x away from blob full data (= 21600 blobs/day) usage peak. We need to launch peerdas and start scaling securely while simultaneously improving L1."

Hoffman continued, "If we increase L1 blocktimes, wouldn't we also increase the supply of blockspace (blobspace)? Focusing on L1 feels synergistic with focusing on both L1 and L2, while focusing on DA only benefits L2."

Vitalik clarified, "If we reduce slot times without changing other variables, then yes. But both are ultimately limited by bandwidth constraints, so if we're happy with gas/blob limits today, we'd also be happy with directly higher gas/blob limits.

So I generally think bandwidth and latency are two separate problems. I do think reducing L1 slot times is worth discussing, although it needs to be done carefully to avoid 'killing' independent stakers, or even geographically distributed stakers."
