According to a report by “The Block,” Ethereum co-founder Vitalik Buterin emphasized the need for internal scaling and parallelization of Layer 2 Rollups in his latest article released on Thursday (28th) following the completion of the Dencun hard fork earlier this month.
Vitalik pointed out that while the Dencun hard fork has been successful in reducing transaction costs for Rollups, it has also brought some challenges. He mentioned that the usage of the Ethereum Layer 2 network Base has surged after the Dencun upgrade, leading to hitting its internal Gas limit and consequently causing a spike in fees.
According to Vitalik, this highlights the need for change: in addition to optimizing data processing, Rollups should also undergo internal scaling to sustainably manage the increased activity. He wrote:
One of the solutions proposed by Vitalik focuses on the concept of parallelization, which involves enabling these Layer 2 solutions to process multiple transactions or computational tasks simultaneously instead of sequentially. He stated that implementing parallelization strategies proposed in EIP-648 could benefit Rollups, allowing multiple transactions in the EVM to be processed in parallel, thereby increasing scalability.
Vitalik listed parallelization as one of the methods for improving the Ethereum Layer 2 network, along with data compression and Optimistic data technologies such as Plasma and Validiums.
Buterin added that Ethereum’s development focus will gradually transition from Layer 1 issues to the application layer, with a future improvement involving Data Availability Sampling (DAS), which may expand the data space for each slot to 16 MB. Meanwhile, the network will continue to advance its Layer 2-centric scaling strategy.
