In a recent announcement, the Ethereum Foundation outlined its strategic goals for 2026, emphasizing the importance of post-quantum security alongside the enhancement of gas limits within its protocol. This initiative reflects the organization’s commitment to advancing Ethereum’s infrastructure as quantum computing technology evolves.
The Foundation is shifting its development focus to three primary tracks: enhancing scalability, improving user experience, and reinforcing Layer 1 security. Each track aims to address critical aspects of the network’s future operation while ensuring robust security measures.
According to the Foundation, the upcoming phase for Ethereum will prioritize expanding network capacity while preserving long-term resilience and security. Following a successful increase in the gas limit from 30 million to 60 million in the past year, developers are now targeting a future ceiling of over 100 million gas per block.
The necessity for post-quantum readiness has emerged as a vital consideration in various areas of protocol development, driven by the rapid advancements in quantum computing capabilities. The outlined protocol development for 2026 will be structured around three main pillars: ‘Scale’, ‘Improve UX’, and ‘Harden the L1’.
The ‘Scale’ track will integrate efforts previously divided between Layer 1 execution scaling and blob data availability. It will oversee further increases in gas limits, supported by client benchmarking and block-level access lists, alongside additional blob parameter enhancements following recent upgrades. The track will also facilitate ongoing state scaling initiatives, encompassing near-term repricing and history expiry strategies.
In the ‘Improve UX’ track, the goal will be to simplify user interactions with Ethereum through protocol-level adjustments. This will include advancements in native account abstraction and interoperability. Building on EIP-7702, which allows externally owned accounts to temporarily run smart contract code, developers aim to make smart contract wallets the default, minimizing reliance on external infrastructure and additional gas costs.
This track also connects to the post-quantum security initiative, as native account abstraction opens pathways for moving away from ECDSA-based authentication. Interoperability improvements will continue through the Open Intents Framework, accompanied by enhancements in Layer 1 confirmation times and expedited Layer 2 settlements.
The ‘Harden the L1’ track will focus specifically on maintaining Ethereum’s key attributes while the network scales. This includes security enhancements, post-quantum readiness initiatives, and execution-layer protections. Research into transaction censorship resistance and blob data, along with an expanded testing infrastructure, will be integral as protocol updates are implemented at a more rapid pace.
Looking ahead, the Ethereum Foundation has targeted the Glamsterdam upgrade for the first half of 2026, with the Hegotá upgrade slated for later in the year. These advancements are anticipated to include higher gas limits, ongoing blob scaling efforts, and continued progress on separation of proposers and builders, along with improvements in native account abstraction and post-quantum security.
This roadmap signifies a substantial commitment to advancing Ethereum’s capabilities, ensuring it remains competitive and secure in an expanding digital landscape.
