Ethereum’s core development team has announced a significant restructuring of its "Protocol" initiatives for 2026, building on a highly productive 2025 that saw two major network upgrades and substantial progress across critical fronts. The "Protocol" framework, initially introduced in June 2025 to organize development efforts around three strategic initiatives—Scale L1, Scale Blobs, and Improve UX—is now evolving into a more integrated and comprehensive structure designed to meet the growing demands and complexities of the network. This strategic shift aims to accelerate scalability, enhance user experience, and robustly harden the foundational Layer 1, signaling an intensified focus on Ethereum’s long-term sustainability and widespread adoption.
A Retrospective on Ethereum’s Transformative Year: 2025 Milestones
The year 2025 emerged as one of Ethereum’s most impactful periods at the protocol level, marked by the successful deployment of two pivotal network upgrades: Pectra and Fusaka. These upgrades, alongside continuous community-driven enhancements, laid critical groundwork for the network’s future.
The Pectra upgrade, deployed on the mainnet in May 2025, delivered a suite of enhancements aimed at improving both user functionality and network efficiency. A cornerstone of Pectra was the implementation of EIP-7702, a groundbreaking proposal that empowers Externally Owned Accounts (EOAs) to temporarily execute smart contract code. This innovation unlocked several highly anticipated features, including transaction batching, which allows multiple operations to be bundled into a single transaction, significantly reducing gas costs and improving throughput. It also enabled gas sponsorship, where third parties can cover transaction fees for users, and advanced social recovery mechanisms, bolstering account security and accessibility. EIP-7702 marked a crucial step towards native account abstraction, a long-term goal for enhancing user experience by making accounts more flexible and programmable.
Beyond EIP-7702, Pectra also dramatically doubled blob throughput, a vital improvement for Layer 2 scaling solutions. Blobs, introduced in the Dencun upgrade, provide dedicated space for L2 data, and increasing their capacity directly translates to lower transaction costs and higher data availability for rollups. Furthermore, the upgrade raised the maximum effective validator balance to 2,048 ETH via EIP-7251. This adjustment offers greater flexibility for large-scale stakers and staking pools, while also improving capital efficiency within the staking ecosystem. Complementing this, EIP-6110 dramatically shortened validator onboarding times, making it easier and faster for new validators to join the network. This reduction in onboarding time is critical for maintaining and enhancing network decentralization by lowering the barrier to entry for prospective stakers.
The momentum continued with the Fusaka upgrade, which followed in December 2025. Fusaka’s most significant contribution was the integration of PeerDAS (EIP-7594) onto the mainnet. PeerDAS, or Peer-to-Peer Data Availability Sampling, represents a paradigm shift in how validators handle blob data. Instead of requiring validators to download all blob data in its entirety, PeerDAS enables them to sample small portions of the data to verify its availability. This innovation drastically reduces bandwidth requirements for validators, making it feasible to support a much larger data capacity. Consequently, PeerDAS enabled an 8x increase in theoretical blob capacity, setting the stage for unprecedented scalability for Layer 2 networks. To capitalize on this increased capacity, two Blob Parameter Only (BPO) forks were shipped concurrently with Fusaka, initiating the gradual ramp-up from the initial 6 blobs per block towards much higher targets, further cementing Ethereum’s commitment to L2 scaling.
Between these two landmark upgrades, the Ethereum community also achieved other significant protocol-level improvements. The mainnet gas limit was steadily raised from an initial 30 million to 60 million, marking the first substantial increase since 2021. This increase directly translates to higher transaction capacity on Layer 1, offering more space for transactions and potentially easing congestion and fees, particularly for high-value or time-sensitive operations. Additionally, the implementation of History Expiry removed pre-Merge data from full nodes, resulting in savings of hundreds of gigabytes of disk space. This optimization is crucial for making node operation more accessible and sustainable, reducing hardware requirements and promoting a more decentralized network of full nodes.
On the user experience (UX) front, the Open Intents Framework reached production readiness, providing a robust foundation for more intuitive and powerful dApp interactions. Progress was also made on L1 fast confirmation rule implementations across various consensus clients, a development that will lead to quicker finality for transactions, improving the responsiveness of applications and cross-chain interactions. Furthermore, critical interoperability standards such as ERC-7930 + ERC-7828: Interoperable addresses and names and ERC-7888: Crosschain Broadcaster advanced, signaling a concerted effort to create a more seamless and integrated multi-chain ecosystem. These standards aim to simplify the user experience across different Layer 2s and chains, minimizing friction and reducing the cognitive load for users managing assets and interacting with applications across various environments.
Evolving for 2026: A Refined Strategic Framework
While 2025 was undeniably strong, the Ethereum core development team recognized the need for an evolved organizational structure to tackle future challenges and opportunities more effectively. The original "Protocol" initiatives, though successful in guiding the delivery of Pectra and Fusaka, were closely tied to near-term deliverables like increasing the gas limit and shipping PeerDAS. With these milestones achieved, the team now has the opportunity to think at a higher, more strategic level, leading to the introduction of three new, integrated tracks for 2026: Scale, Improve UX, and Harden the L1.
1. The Scale Track: Unifying Growth Efforts
Led by Ansgar Dietrichs, Marius van der Wijden, and Raúl Kripalani
The new Scale track represents a significant strategic consolidation, merging the previously distinct "Scale L1" and "Scale Blobs" initiatives into a single, cohesive effort. This unification acknowledges a fundamental reality in Ethereum development: the work of increasing Layer 1 execution capacity and expanding data availability throughput are inherently intertwined. Gas limit increases, for instance, are heavily dependent on optimizing execution engine performance, while blob scaling relies on complex networking and consensus changes that often touch the same core client codebases.
Coordinating these interdependent efforts under one unified track is expected to yield substantial benefits. It promises to accelerate development cycles, reduce redundant work, and foster a more holistic view of network scalability challenges. The Scale track will focus on pushing the boundaries of what Ethereum’s base layer can handle, not just in terms of transaction throughput, but also in data availability for the burgeoning Layer 2 ecosystem. This includes continued research and implementation of sharding improvements, state growth management, and further optimizations to the Ethereum Virtual Machine (EVM) to support higher gas limits without compromising decentralization or security. The team will also explore advanced data availability solutions beyond PeerDAS, aiming for even greater theoretical blob capacity and lower data costs for rollups, ultimately driving down transaction fees for end-users across the ecosystem.
2. The Improve UX Track: Towards Seamless Interaction
Led by Barnabé Monnot and Matt Garnett
The Improve UX track carries forward the spirit of last year’s initiative but with a sharper, more concentrated focus on two areas deemed highest-leverage for Ethereum’s usability in 2026: native account abstraction and interoperability. These areas are critical to transitioning Ethereum from a technically robust blockchain to a truly user-friendly platform accessible to a mainstream audience.
On the front of native account abstraction (AA), EIP-7702 was an important precursor, providing a glimpse into the future of flexible accounts. However, the ultimate vision for Ethereum is a world where smart contract wallets are the default, operating seamlessly without the need for bundlers, relayers, or incurring extra gas overhead. This involves embedding smart account logic directly into the protocol itself. Proposals like EIP-7701 and the more recent EIP-8141 (Frame Transactions) are at the forefront of this effort, aiming to make smart accounts a native feature of the Ethereum protocol, simplifying user onboarding, enhancing security through programmable recovery mechanisms, and enabling advanced features like multi-signature transactions and batched approvals without complex workarounds.
A fascinating intersection of native AA development is its role in post-quantum readiness. As the threat of quantum computing looms, native account abstraction offers a natural and elegant migration path away from the currently dominant ECDSA-based authentication schemes. By making accounts inherently programmable, users can transition to quantum-resistant signature algorithms with greater ease and flexibility. Complementary to this, the Improve UX track will also explore a number of proposals aimed at making the verification of these quantum-resistant signatures much more gas-efficient within the EVM, ensuring that future-proofing the network doesn’t come at the cost of prohibitive transaction fees.
Regarding interoperability, the track will build upon the foundation established by the Open Intents Framework. The overarching goal remains the realization of seamless, trust-minimized cross-Layer 2 interactions. This vision is crucial for a future where users can move assets and interact with applications across various L2s and sidechains with the same ease as navigating within a single application. Continued progress on faster L1 confirmations and shorter L2 settlement times directly supports this objective, as quicker finality on the base layer significantly reduces the latency and trust assumptions required for cross-chain communication. The team will focus on standardizing communication protocols, improving message passing, and developing infrastructure that abstracts away the complexities of interacting with a multi-L2 ecosystem.
3. The Harden the L1 Track: Ensuring Core Integrity
Led by Fredrik Svantes, Parithosh Jayanthi, and Thomas Thiery
The "Harden the L1" track is a brand-new addition to Protocol’s organizational structure, underscoring a critical and dedicated focus on preserving Ethereum’s fundamental properties as it continues to scale and evolve. This track acknowledges that rapid growth must be balanced with an unwavering commitment to the core tenets that make Ethereum valuable: security, decentralization, and censorship resistance.
This track encompasses several vital areas. One primary focus will be on enhancing the security and resilience of the Ethereum protocol against increasingly sophisticated attacks. This includes continuous auditing of client implementations, improving formal verification methods for core protocol logic, and developing advanced threat models to anticipate and mitigate potential vulnerabilities. The team will also delve into client diversity initiatives, ensuring that no single client implementation dominates the network, thereby reducing the risk of a single point of failure that could compromise the entire chain. Maintaining robust client diversity is a cornerstone of decentralization and network resilience.
Furthermore, a significant component of "Harden the L1" will be dedicated to bolstering censorship resistance. As the network scales and the complexity of transaction ordering and block production grows, ensuring that no single entity or group can unduly influence or censor transactions becomes paramount. This involves exploring and implementing solutions such as enshrined Proposer-Builder Separation (ePBS), which aims to decentralize the block production process and reduce the power of block builders to engage in censorship or extract excessive Maximal Extractable Value (MEV). The track will also investigate other mechanisms to ensure fair and equitable access to the network for all users and applications, irrespective of their size or influence.
Finally, this track will also consider the long-term health and sustainability of the Layer 1 network, including state growth management, client efficiency, and ensuring that operating a full node remains accessible to a broad range of participants. By proactively addressing these foundational concerns, the "Harden the L1" track aims to ensure that Ethereum remains a secure, decentralized, and credibly neutral platform well into the future, even as it undergoes profound transformations to meet global demand.
Looking Ahead: Glamsterdam, Hegotá, and Beyond
The roadmap for 2026 is ambitious, with the Glamsterdam network upgrade targeted for the first half of the year, followed by Hegotá later in the year. These upgrades are poised to introduce significant advancements, including the potential for parallel execution to further boost L1 throughput, continued increases in gas limits, and the implementation of enshrined PBS. The unwavering commitment to continued blob scaling will ensure Layer 2s have ample data availability, while ongoing efforts in censorship resistance, native account abstraction, and post-quantum security underscore Ethereum’s dedication to long-term viability and user empowerment.
The restructured Protocol framework for 2026 represents a mature and integrated approach to Ethereum’s development. The achievements of 2025, from the flexible accounts of Pectra to the unprecedented data availability of Fusaka, have not only pushed the boundaries of what a blockchain can achieve but have also informed a more strategic and focused path forward. The unification of scaling efforts, the sharpened focus on user experience through native account abstraction and interoperability, and the introduction of a dedicated track to harden the Layer 1 collectively signify a robust and forward-thinking strategy.
For users, this means a future with potentially lower transaction fees, faster interactions, and a more intuitive, secure, and integrated experience across the Ethereum ecosystem. For developers, it means a more powerful and flexible platform upon which to build the next generation of decentralized applications. For the network itself, it means greater resilience, decentralization, and adaptability in the face of evolving technological landscapes and increasing global demand. The Ethereum community is encouraged to follow these developments closely, with track-level updates anticipated soon and protocol.ethereum.foundation serving as the central hub for information and engagement. The message from the core developers is clear: the work continues, and the commitment to shipping a more scalable, usable, and robust Ethereum remains paramount.
