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 published on Thursday the 28th after the Dencun hard fork was completed 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 Ethereum’s Layer 2 network, Base, has significantly increased after the Dencun upgrade, leading to hitting its internal gas limit and causing a surge in fees.
According to Vitalik, this highlights the need for changes: besides 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 allowing 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 by enabling parallel processing of multiple transactions in the EVM, thereby increasing scalability.”
Vitalik listed parallelization as one of the methods that can improve Ethereum’s 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 shift from Layer 1 issues to the application layer, and a future improvement involves Data Availability Sampling (DAS), which could expand the data space for each slot to 16 MB. Meanwhile, the network will continue to advance its layer-centric expansion strategy.
