Ethereum co-founder Vitalik Buterin has outlined a potential direction for the network’s next major upgrade, hinting at a suite of changes designed to dramatically improve scalability and further integrate layer-2 solutions. In a series of posts on a public forum, Buterin described a roadmap that would build on the foundation of the Merge, the 2022 transition that moved Ethereum from proof-of-work to proof-of-stake.
The ‘Surge’ and Beyond: What Buterin Proposed
Buterin’s proposal, which he has informally referred to as part of a broader ‘Surge’ phase, centers on several key technical upgrades. The primary goal is to increase Ethereum’s capacity to process transactions without sacrificing decentralization or security. This would be achieved by making it cheaper and easier for layer-2 networks—such as Arbitrum, Optimism, and zkSync—to post data to the main Ethereum chain.

One specific technical change discussed is a potential upgrade to Ethereum’s data availability layer, often referred to as ‘danksharding’ or ‘proto-danksharding’ (EIP-4844). This upgrade, already in development, would create a new, temporary data storage space on Ethereum specifically for layer-2 networks, drastically reducing their fees. Buterin’s latest comments suggest this is just the beginning, with further optimizations planned to make the entire system more efficient.
Why This Matters for Ethereum Users
For the average user, the most immediate benefit of these upgrades would be lower transaction fees. While the Merge reduced Ethereum’s energy consumption by over 99%, it did not directly lower gas fees. The current roadmap explicitly targets that pain point. If successful, the upgrades could make Ethereum more competitive with faster, cheaper blockchains like Solana, while retaining its established security and developer ecosystem.

The proposal also signals a strategic shift in Ethereum’s development philosophy. Rather than trying to do everything on the main chain, the network is doubling down on a ‘rollup-centric’ roadmap, where the main chain acts as a secure settlement and data layer, while most user activity happens on faster, cheaper layer-2 networks.
Uncertainties and the Path Forward
Buterin’s comments are preliminary and do not represent a finalized plan. Any major upgrade to Ethereum requires extensive research, development, testing, and community consensus. The timeline remains uncertain, with some upgrades expected within the next year and others potentially taking several years. The Ethereum Foundation has not issued an official statement on the specific proposals outlined by Buterin.
Despite the uncertainty, the direction is clear: Ethereum is preparing for its next major phase, one focused on scaling to meet global demand. For developers and users, the coming years could bring the most significant changes to the network since its inception.
Frequently Asked Questions
What is the main goal of Ethereum’s next upgrade?
The primary goal is to improve scalability, allowing the network to process more transactions per second and reduce fees, particularly through better integration with layer-2 solutions.
Will the next upgrade require another hard fork like the Merge?
Yes, major upgrades like the ones Buterin described typically require a hard fork, where all Ethereum nodes must upgrade their software to stay on the same network.
How will layer-2 users benefit from this upgrade?
Layer-2 users would likely see even lower fees and faster transaction finality, as the main chain becomes more efficient at handling data from these secondary networks.
