Following the successful Dencun hard fork, Ethereum co-founder Vitalik Buterin has highlighted the urgent need for internal scaling and parallelization within Layer 2 Rollups. In his latest article, Vitalik addresses the challenges and opportunities post-Dencun, particularly for Ethereum’s scalability.
Key Takeaways from Vitalik’s Analysis
Dencun’s Success & Challenges:
- While Dencun reduced Rollup transaction costs, it also exposed bottlenecks in handling increased activity (e.g., Base network’s gas fee spikes due to surging demand).
Quote from Vitalik:
"This has made it clear that scaling must occur not just in Ethereum’s data space but also inside Rollups."
Parallelization as a Solution:
- EIP-648 proposes parallel transaction processing within the EVM, enabling Rollups to handle multiple tasks simultaneously.
- Benefits: Higher throughput and lower fees.
Additional Scaling Strategies:
- Data compression
- Optimistic data techniques (e.g., Plasma, Validiums)
- Future Data Availability Sampling (DAS) could expand per-slot data capacity to 16MB.
Ethereum’s Roadmap: From Layer 1 to Application Layer
- Focus shifts to app-layer optimizations while maintaining L2-centric scaling.
- Development continues on DAS and blob space expansion.

FAQs
Q: What caused Base network’s fee spikes post-Dencun?
A: Surging transaction volume hit internal gas limits, revealing Rollup-level scaling needs.
Q: How does EIP-648 improve Rollup performance?
A: It introduces parallel processing to the EVM, reducing sequential execution delays.
