In a recent deep dive into Ethereum’s future scalability and infrastructure, Ethereum co-founder Vitalik Buterin discusses the latest introduction of blobs and their significant role in the evolution of layer two (L2) rollups. This pivotal development marks a transition towards more efficient internal scaling and parallelization within Ethereum’s ecosystem, according to Buterin.


Scaling Ethereum: Buterin on Parallelization, Blobs, and L2 Rollups

Vitalik Buterin‘s latest blog post highlights the Dencun hard fork, a crucial update that brought proto-danksharding (aka EIP-4844 aka blobs) into existence, significantly reducing rollup transaction fees by a factor of over 100. This achievement is not just a milestone but a gateway to Ethereum’s scaling becoming a “one-to-N” problem, as described by Buterin.

The Ethereum co-founder wrote:

From here, important scaling work, both in increasing blob count and in improving rollups’ ability to make the best use of each blob, will continue to take place, but it will be more incremental. The scaling-related changes to the fundamental paradigm of how Ethereum as an ecosystem operates are increasingly already behind us.

The emphasis he said, is now shifting towards optimizing these blobs’ usage and enhancing rollups’ efficiency, which is essential for Ethereum’s long-term vision of scalable, decentralized applications (dapps). The transition towards an L2-centric Ethereum is well underway, with major applications migrating to L2 solutions, thereby setting a new standard for payments and wallet interactions.

Buterin wrote that he envisions a future where Ethereum’s scalability is further augmented through techniques like data availability sampling, allowing for even more substantial expansions in data space. This is coupled with the necessity for L2 protocols to evolve, he stressed, utilizing advancements in data compression and security enhancements to ensure robust and efficient operations.

Buterin asserts, “Now that we have blobs, this key constraint that has been holding us back all this time is starting to melt away.” This statement underscores the critical role of blobs in alleviating past limitations, propelling Ethereum towards a new era of low-fee, high-capacity blockchain infrastructure. Buterin’s insights emphasize the progression towards this scalable future is not without its challenges, including the need for ongoing development in both the layer one (L1) protocol and L2 solutions.
