Scaling Ethereum: Innovations and Future Goals

Scaling Ethereum- The Future of Ethereum: Vitalik Buterin’s Scaling Strategy

Scaling Ethereum– Ethereum co-creator Vitalik Buterin has set an ambitious goal of achieving over 100,000 transactions per second (TPS) across both Layer 1 and Layer 2 networks. In a recent blog post, he outlined this target as part of a long-term strategy for scaling the Ethereum network. Buterin emphasized that while the rollup-centric roadmap will remain the core scaling strategy, it will encounter unique challenges that must be addressed.

The Rollup-Centric Roadmap: Key to Ethereum’s Future

Buterin’s roadmap, dubbed The Surge, aims to complete the rollup-centric approach, which merges sharding and Layer 2 protocols. He stated, Our task is to bring the rollup-centric roadmap to completion, and solve these problems, while preserving the robustness and decentralization that makes the Ethereum L1 special.

This approach not only focuses on achieving the 100,000 TPS goal but also emphasizes the importance of maintaining the decentralization and security of the Layer 1 mainnet. Additionally, maximizing interoperability across Layer 2 solutions remains a priority. Despite the recent Dencun upgrade and the introduction of blobs, Buterin noted that Ethereum still struggles with speed, calling for further enhancements in transaction processing.

Improving Transaction Speed and Data Availability

To enhance transaction speeds, Buterin explored methods for improving data availability sampling, which allows the network to verify data availability without requiring each node to download all the data. He set a medium-term target of achieving 16 MB per slot of data availability bandwidth, which could potentially result in up to 58,000 TPS—significantly higher than the current maximum of 375 kB per slot for rollups on Ethereum. However, Buterin cautioned that even this target might not be sufficient for high-bandwidth sectors like consumer payments or decentralized social applications.

For these high-volume, low-value applications, he suggested implementing a solution known as Plasma. This involves an operator publishing blocks off-chain and posting a portion of the data, or Merkle roots, on-chain, which could enhance transaction efficiency.

Scaling the Mainnet: Addressing Gas Limits and Decentralization

In his blog post, Buterin also proposed strategies for further scaling the base layer, particularly through a more effective gas limit increase. He pointed out that the existing disparity in scalability between Layer 2s and Layer 1 could jeopardize the economic health of ether and destabilize the overall ecosystem.

The easiest way to scale is to simply increase the gas limit, he wrote. However, this risks centralizing the L1, and thus weakening the other important property that makes the Ethereum L1 so powerful: its credibility as a robust base layer.

While a clear strategy for an effective L1 gas limit increase remains undefined, Buterin suggested making specific parts of Ethereum more affordable without increasing risks to decentralization. This could involve implementing different fees for various types of calculations or adopting a more efficient bytecode format known as EOF.

Buterin’s latest insights build on previous discussions about critical issues, such as the 15-minute block finalization time and the 32 ether requirement to become a validator. These challenges highlight the ongoing technical evolution of Ethereum as it aims to secure its position as a leading platform in the blockchain ecosystem.
