Vitalik Buterin Lays Out Grand Vision For Ethereum Layer-2s with ‘The Surge’ Roadmap

He also touched on Etheruem’s rollup-centric approach, which focuses on shifting most transaction processing to layer-2 networks, like rollups, while keeping Ethereum’s main blockchain secure. This way, the core Ethereum chain acts as a secure base layer, and the rollups handle scaling by bundling multiple transactions off-chain, ensuring faster speeds and lower fees without compromising the network’s integrity.

The task ahead is to complete the roadmap by addressing challenges while preserving the robustness of its settlement layer. Ethereum will continue serving as a secure and decentralized foundation, leaving layer-2s responsible for scaling, the co-founder said. One of the critical challenges, Buterin noted, is balancing the scalability trilemma: decentralization, scalability, and security. Buterin’s proposal incorporates cryptographic solutions like SNARKs to ensure transaction integrity without overwhelming the network’s nodes. 

A critical part of Ethereum’s roadmap is ensuring layer-2s inherit Ethereum’s core principles of trustlessness, openness, and censorship resistance, he explained. The roadmap also suggests maximum interoperability between layer-2s. As Buterin puts it, “Ethereum should feel like one ecosystem, not 34 different blockchains.”

Buterin also highlighted recent developments, including the introduction of EIP-4844 data blobs, which have sought to improve data bandwidth, making Ethereum better equipped to handle higher transaction volumes.  “These changes bring us closer to our goal: 100,000+ TPS on L1+L2 while preserving decentralization and robustness of layer-1,” Buterin wrote.
