From Glamsterdam to ZK-EVM: How Vitalik Buterin Reshaped Ethereum's Scaling Roadmap

Ethereum’s scalability challenges have long been a focus in the industry. Recently, Vitalik Buterin discussed the technical evolution of Ethereum, outlining a phased solution framework that ranges from recent engineering optimizations to long-term fundamental innovations, providing a clear technical roadmap for Ethereum’s scalability.

Recent Breakthrough: Engineering Optimization in the Glamsterdam Upgrade

The Glamsterdam upgrade marks the first step in Ethereum’s expansion. According to Vitalik Buterin, this upgrade will optimize block validation efficiency on multiple levels. By deploying access list mechanisms at the block level, validators can complete block validation more quickly. Meanwhile, the introduced ePBS (separating proposer and builder) mechanism allows ample time for block validation, avoiding delays caused by time pressure.

More importantly, this upgrade will dynamically adjust gas fee prices based on actual execution time. This improvement directly addresses the core issue: different operations consume varying amounts of computational resources but are priced uniformly.

The Nemesis of State Bloat: Multidimensional Gas Fee Mechanism

While an important innovation in the Glamsterdam upgrade is the introduction of multidimensional gas, its significance in Vitalik Buterin’s plan is even deeper. Multidimensional gas distinguishes between different resource consumptions—storage operations, computation, network resources, etc.—providing a more precise reflection of costs.

The upgrade will handle the cost of state creation separately, so that gas used for creating state is no longer included in the standard gas limit, leaving room for deploying complex smart contracts. The EVM maintains compatibility through the introduction of a “storage repository” mechanism, ensuring that subroutine calls and gas-related operations continue to function normally.

Long-term Vision: Fusion of ZK-EVM and Data Availability

For Ethereum’s future development, Vitalik Buterin emphasizes the importance of ZK-EVM (Zero-Knowledge Proof Virtual Machine) and data blobs. Through iterative improvements like PeerDAS, Ethereum aims to achieve a data availability target of 8 MB per second. Realizing this goal means users can verify block data directly without downloading the entire chain, significantly lowering the barrier for validator nodes.

Over time, Ethereum will gradually transition to a multidimensional gas pricing system, maintaining system flexibility while ensuring long-term economic sustainability. This evolutionary path reflects Vitalik Buterin’s comprehensive vision for Ethereum’s future—addressing current performance bottlenecks and laying the foundation for fundamental technological transformation.
