The Ethereum Foundation has officially outlined its strategic direction for the coming year, building upon a remarkably productive 2025 that saw the successful implementation of two major network upgrades, Pectra and Fusaka. The "Protocol" initiative, initially launched in June of the previous year with a focus on scaling Layer 1 (L1), scaling blobs, and improving user experience (UX), has now evolved. The updated strategy for 2026 introduces three core tracks: Scale, Improve UX, and Harden the L1, signaling a deeper commitment to both performance enhancements and the foundational integrity of the Ethereum network.
A Transformative 2025 for Ethereum’s Protocol Layer
The past year has been a watershed moment for Ethereum’s protocol development, marked by significant advancements that have fundamentally reshaped its capabilities. The Pectra upgrade, deployed to mainnet in May 2025, introduced a suite of crucial enhancements. Foremost among these was EIP-7702, a groundbreaking Ethereum Improvement Proposal that empowers Externally Owned Accounts (EOAs) with the temporary ability to execute smart contract code. This innovation unlocks a cascade of new functionalities, including transaction batching, which allows users to combine multiple operations into a single transaction, thereby reducing gas costs and improving efficiency. Furthermore, it paves the way for gas sponsorship, enabling third parties to subsidize transaction fees for users, and facilitates social recovery mechanisms, offering users more robust options for regaining access to their accounts if they lose their private keys.
Beyond these user-centric features, Pectra also delivered substantial improvements to the network’s infrastructure. It effectively doubled the throughput for blob data, a critical component for Layer 2 scaling solutions like rollups. The maximum effective validator balance was also significantly increased to 2,048 ETH, aiming to optimize validator participation and network security. Moreover, validator onboarding times were dramatically reduced, streamlining the process for new participants to join and secure the network.
Following Pectra, the Fusaka upgrade arrived in December 2025, bringing the highly anticipated PeerDAS (Decentralized Availability Sampling) to mainnet. This paradigm shift moved validators from downloading entire blob data blobs to sampling them, drastically reducing bandwidth requirements. The impact is profound: a theoretical eightfold increase in blob capacity is now achievable, providing a substantial boost for data availability and further empowering Layer 2 solutions. Alongside Fusaka, two Blob Parameter Only (BPO) forks were released, initiating a gradual transition from the initial six blobs per block towards significantly higher targets, signaling a clear roadmap for escalating data handling capabilities.
These protocol-level achievements were complemented by broader network enhancements throughout 2025. The mainnet gas limit was steadily raised from an initial 30 million to 60 million, representing the first substantial increase since 2021 and a direct consequence of the performance gains realized through Pectra and Fusaka. The introduction of history expiry, a feature that removes pre-Merge data from full nodes, has resulted in substantial disk space savings, potentially reducing storage requirements by hundreds of gigabytes for node operators.
On the user experience front, significant strides were made. The Open Intents Framework reached production, aiming to standardize how users express their desired actions on the blockchain. Progress was also evident in the implementation of L1 fast confirmation rule proposals across various consensus clients, a crucial step towards reducing transaction finality times. Furthermore, interoperability standards saw meaningful advancement, with initiatives like ERC-7930 + ERC-7828 (Interoperable addresses and names) and ERC-7888 (Crosschain Broadcaster) moving forward, laying the groundwork for a more connected and seamless multi-chain Ethereum ecosystem.
The cumulative impact of these developments positions 2025 as a pivotal year in Ethereum’s ongoing evolution. The successful execution of these complex upgrades underscores the maturity and capability of the Ethereum research and development community.
Evolving Strategy: The Three Pillars of Ethereum Protocol Development in 2026
While 2025 focused on specific, near-term deliverables that directly addressed immediate scaling and UX challenges, the Ethereum Foundation’s perspective has broadened. With key milestones like gas limit increases and PeerDAS implementation now behind them, the organization is refining its strategic framework to address the evolving needs of the Ethereum community and the broader blockchain landscape. Starting in 2026, Ethereum’s protocol development will be organized under three distinct, yet interconnected, tracks: Scale, Improve UX, and Harden the L1.
Scale: Unifying Execution and Data Availability
The "Scale" track, spearheaded by Ansgar Dietrichs, Marius van der Wijden, and Raül Kripalani, represents a consolidation of the previous "Scale L1" and "Scale Blobs" initiatives. This unification reflects a pragmatic understanding of the interwoven nature of increasing L1 execution capacity and expanding data availability throughput. The development teams recognize that advancements in one area invariably impact the other. For instance, efforts to raise the gas limit are directly contingent on the performance of the execution engine, while blob scaling relies on networking and consensus modifications that often involve shared client codebases. By bringing these efforts under a single umbrella, the Ethereum Foundation aims to accelerate progress and foster a more holistic approach to scaling.
The core objectives for the Scale track in 2026 include:
- Elevating Execution Capacity: This involves further optimizations to the Ethereum Virtual Machine (EVM) and the underlying execution clients to support substantially higher gas limits. The target is to accommodate a significantly greater volume of transactions per block, thereby increasing the overall throughput of the L1 network.
- Expanding Data Availability: Building on the success of PeerDAS, the Scale track will focus on further increasing blob throughput and capacity. This includes the planned transition to higher blob targets, as initiated by the BPO forks alongside Fusaka, and potentially exploring more advanced data availability sampling techniques.
- Optimizing Network Performance: This encompasses improvements to the peer-to-peer networking layer, ensuring efficient propagation of transaction and block data across the network, which is critical for both execution and data availability scaling.
- Streamlining Client Development: A unified Scale track is expected to lead to better coordination and code sharing among different client implementations (e.g., Geth, Besu, Nethermind), reducing redundant development efforts and promoting consistency.
Improve UX: Towards Native Account Abstraction and Seamless Interoperability
The "Improve UX" track, led by Barnabé Monnot and Matt Garnett, continues the vital work of enhancing the user experience on Ethereum. While building upon the foundational work of EIP-7702 introduced in Pectra, this track now sharpens its focus on two paramount areas: native account abstraction and robust interoperability.
The ultimate goal for account abstraction is to make smart contract wallets the default for all users, eliminating the current reliance on bundlers, relayers, and additional gas overhead associated with existing solutions. Proposals such as EIP-7701 and the more recent EIP-8141 (Frame Transactions) are actively pushing towards embedding smart account logic directly into the protocol. This integration aims to simplify wallet management, enable more advanced security features, and abstract away the complexities of interacting with the blockchain for the average user.
A significant implication of this focus on native account abstraction is its synergy with post-quantum readiness. By transitioning to smart contract wallets as the default, Ethereum can naturally facilitate a migration away from the current reliance on ECDSA-based authentication, which is vulnerable to quantum computing attacks. Complementary proposals are also in development to significantly enhance the gas efficiency of verifying quantum-resistant signatures within the EVM, a crucial step in future-proofing the network’s security.
On the interoperability front, the Improve UX track is committed to building upon the foundation laid by the Open Intents Framework. The overarching objective remains to enable seamless, trust-minimized cross-Layer 2 interactions. This vision is being progressively realized through ongoing advancements in faster L1 confirmations and reduced L2 settlement times, which are essential for creating a fluid and interconnected multi-chain ecosystem. The development of standardized cross-chain communication protocols, such as the aforementioned ERC-7888, is critical to achieving this goal.
Harden the L1: Safeguarding Ethereum’s Core Principles
A notable addition to the strategic framework is the "Harden the L1" track, led by Fredrik Svantes, Parithosh Jayanthi, and Thomas Thiery. This new track signifies a dedicated focus on ensuring that as Ethereum scales and evolves, it steadfastly retains the core properties that underpin its value proposition: decentralization, security, and censorship resistance.
The "Harden the L1" track will encompass several critical areas:
- Censorship Resistance: This involves actively developing and implementing mechanisms to counter potential censorship attempts by nodes or validators, ensuring that legitimate transactions can always be processed. This could include advancements in transaction ordering, data availability guarantees, and network-level resilience.
- Decentralization: Efforts will be directed towards maintaining and enhancing the decentralized nature of Ethereum. This may involve research into more accessible validator requirements, improved client diversity, and measures to prevent excessive centralization of node operation or staking power.
- Security Enhancements: Beyond post-quantum readiness, this track will explore other avenues for bolstering the L1’s security. This could include further research into consensus mechanism robustness, slashing conditions, and the overall security posture of the proof-of-stake (PoS) network.
- Verifiability and Auditability: Ensuring that the L1 remains transparent and auditable is paramount. This track will focus on improvements that make it easier for developers, researchers, and users to understand, verify, and audit the state and operations of the Ethereum network.
- Economic Security: Maintaining a robust economic security model for Ethereum is crucial. This track may involve research into validator incentives, fee mechanisms, and the overall economic sustainability of the network as it scales.
Looking Ahead: The Glamsterdam and Hegotà Upgrades
The roadmap for 2026 is ambitious, with two major network upgrades planned: Glamsterdam, targeted for the first half of the year, and Hegotà, scheduled for later in the year. These upgrades are expected to embody the strategic shifts outlined in the new three-track approach.
Glamsterdam is anticipated to introduce parallel execution, a significant leap forward in transaction processing capability that will likely be tied to further gas limit increases. It is also expected to bring enshrined proposer-builder separation (PBS), a key development for optimizing block production and enhancing network efficiency. Continued advancements in blob scaling and progress on censorship resistance are also high on the agenda.
Hegotà, following later in the year, will likely build upon these advancements and further address areas such as native account abstraction and the critical transition to post-quantum security. The dual upgrade strategy underscores a commitment to rapid, iterative progress in strengthening Ethereum’s infrastructure and user experience.
