L2 sequencer and bridge concerns
);)
Buterin stated in an official X post on the 3rd, "The original vision regarding L2 and its role in Ethereum no longer holds true, and a new path is needed." Buterin assessed that the current rollup-centric structure has deviated from initial expectations.
Buterin’s critique focused on the fact that some L2 designs concentrate transaction processing authority in the hands of a few operators and rely on separate trust mechanisms during asset transfers. Buterin viewed this structure as having limitations in establishing itself as a core solution for Ethereum’s scalability.
Reactions from the L2 industry were mixed. Karl Floersch, co-founder of Optimism, stated that as technological constraints persist, L2 must evolve into a broader role beyond simple expansion.
On the other hand, Steven Goldfeder, co-founder of Offchain Labs, countered that the scalability of rollups remains key. Goldfeder explained that rollups consistently handle higher transaction throughput than the Ethereum main chain.
This controversy is leading to discussions regarding the direction of the Ethereum ecosystem—whether to maintain a scaling strategy centered on rollups or to seek a new structure. Industry observers suggest that the role of L2 is escalating beyond a simple auxiliary network into a key issue that requires redesigning the entire structure of Ethereum.
