Ethereum Co-Founder Vitalik Buterin Calls for Increased Layer-1 Capacity

Ethereum co-founder Vitalik Buterin has underscored the critical need to expand the network's layer-1 (L1) capacity to ensure robust censorship resistance, interoperability, and security. In a recent blog post, Buterin argued for raising Ethereum's gas limit beyond its current 36 million threshold, emphasizing the importance of L1 scalability even as layer-2 (L2) solutions continue to develop.

The Case for L1 Scalability

Buterin highlighted several key reasons for increasing L1 capacity:

• Censorship Resistance: A stronger L1 ensures the network can withstand censorship attempts and serve as a reliable fallback for L2 systems.
• Interoperability: L1 plays a crucial role in facilitating transfers of low-volume assets and NFTs between L2 platforms.
• Security: Maintaining ERC-20 token issuance on L1 reduces risks associated with hostile governance changes on L2 platforms.

Addressing L2 Challenges

Buterin also addressed potential risks associated with relying too heavily on L2 solutions. He warned that Ethereum's current L1 capacity might be insufficient to handle mass withdrawals if a major L2 system fails. Without optimizations, Ethereum may need to scale several times over—potentially up to 9 times—to manage such scenarios efficiently.

The Role of Interoperability

Interoperability between L2 platforms remains a significant challenge, particularly for low-volume assets and NFTs. Buterin suggested that a 5.5x increase in L1 capacity could reduce transfer costs to acceptable levels, improving the overall user experience.

Security Concerns and ERC-20 Issuance

Buterin expressed concerns about the security implications of ERC-20 token issuance on L2 platforms. He proposed that keeping ERC-20 issuance on L1 could mitigate risks associated with hostile governance changes on L2 platforms, which could lead to unchecked token minting and broader ecosystem impacts.

Ethereum's Roadmap and Upcoming Upgrade

Ethereum's rollup-centric roadmap has alleviated some network congestion and reduced transaction costs. However, this shift has also led to a decline in mainnet fee revenue, which recently dropped below $1 million for the first time since September. The upcoming Pectra upgrade, scheduled for April 8, aims to further enhance scalability by doubling the target number of "blobs" per block and introducing a staker-voted mechanism for adjusting such parameters.

Conclusion

Buterin's call for increased L1 capacity underscores the importance of balancing layer-1 and layer-2 solutions to create a more robust and resilient Ethereum ecosystem. As the network continues to evolve, addressing these challenges will be critical to maintaining its position as a leading blockchain platform.
