What Are the 2026 Protocol Priorities for Ethereum?

The Ethereum Foundation published a 'Protocol Priorities Update for 2026' on Feb. 18, outlining how core R&D will be organized this year and what the next upgrade cycle will emphasize. The update looks back at 2025 as a high-throughput year for mainnet changes, anchored by two network upgrades: Pectra in May and Fusaka in December, with PeerDAS on mainnet.

For 2026, Protocol work is grouped into three tracks: Scale, Improve UX, and Harden the L1, each with named leads. The Scale track, led by Ansgar Dietrichs, Marius van der Wijden, and Raúl Kripalani, merges last year's 'Scale L1' and 'Scale Blobs' initiatives into one effort. The foundation highlights continued gas limit increases 'toward and beyond 100M,' supported by block-level access lists via EIP-7928 and ongoing client benchmarking.

The Improve UX track, led by Barnabé Monnot and Matt Garnett, focuses on native account abstraction and interoperability, with EIP-7702 as a step toward smart contract wallets becoming the default. Interoperability work aims for seamless, trust-minimized cross-L2 interactions. The Harden the L1 track, led by Fredrik Svantes, Parithosh Jayanthi, and Thomas Thiery, is framed as insurance policy work preserving Ethereum's core properties. Looking ahead, the foundation targets Glamsterdam for the first half of 2026, with Hegotá planned later in the year.

The ambition includes parallel execution, significantly higher gas limits, enshrined PBS, continued blob scaling, and progress on censorship resistance, native account abstraction, and post-quantum security. The Ethereum Foundation has outlined its 2026 plans, focusing on three main areas: scaling, user interface (UI) improvement, and L1 enhancement. In 2025, two major updates were implemented: Pectra and Fusaka.

What Is the Impact of the 2026 Upgrades on Ethereum's Future?

The 2026 protocol update builds on the Pectra and Fusaka upgrades of 2025, with goals of enhancing scalability, user experience, and quantum resistance. The Scale track aims to increase the gas limit from 60 million to 100 million or more, allowing more transactions per block and reducing fees during peak times. Advanced tools like Enshrined Proposer-Builder Separation (ePBS), Block-level Access Lists, and increased blob capacity support these efforts.

The zkEVM Focus allows validators to verify large blocks using zero-knowledge proofs, enabling faster transaction processing. The Improve UX track, led by Barnabé Monnot and Matt Garnett, focuses on making Ethereum more user-friendly with simpler tools and interoperability across Layer-2 networks. The Harden L1 track, led by Vitalik Buterin and others, prepares Ethereum for quantum computing threats by exploring post-quantum signatures and enhancing censorship resistance.

The Ethereum Foundation has outlined its 2026 plans, focusing on three main areas: scaling, user interface (UI) improvement, and L1 enhancement. In 2025, two major updates were implemented: Pectra and Fusaka. These upgrades increased the gas limit to 60 million, introduced PeerDAS, expanded blob data throughput, and took a step toward native account abstraction. Looking ahead to 2026, the key tasks include increasing the gas limit to 100 million and above, further scaling of L1 and blob data, developing native account abstraction, improving interactions between L2 solutions, and strengthening security and censorship resistance. The first major update of 2026, Glamsterdam, is expected in the first half of the year.

The Ethereum Foundation has also outlined its 2026 protocol priorities, building on 2025 upgrades like Pectra and Fusaka, which improved smart contract functionality, validator performance, and data efficiency. Major 2026 upgrades, Glamsterdam and Hegotá, aim to enhance scalability, security, and user experience, with a focus on account abstraction and cross-chain tooling.

Ethereum is undergoing significant technical and structural upgrades in 2026 to improve scalability, user experience, and security. The 2026 protocol updates include larger blocks, improved gas limits, and quantum-resistant cryptography, building on prior upgrades like Pectra and Fusaka. These changes aim to enhance Ethereum's transaction speed and reduce fees, making it more competitive in the crypto space.

Institutional adoption is also growing, with staking ETFs like BlackRock's ETHB enabling investors to generate yield through staking without managing staking infrastructure directly. This development is expected to attract more institutional investors seeking exposure to Ethereum.

Ethereum's dominance in DeFi is notable, with 57% of total value locked in its ecosystem. The anticipated Digital Asset Market Clarity Act could provide regulatory clarity, potentially reshaping the Ethereum market in a way similar to the Genius Act from the previous year. These regulatory and technical catalysts are expected to play a crucial role in Ethereum's future growth and institutional appeal.

Ethereum has reached a significant milestone where the Proof-of-Stake (PoS) contract address holds 50% of the total historical ETH issuance. This development highlights increased network security and a potential supply shock due to the declining liquid ETH supply. Institutional accumulation is also on the rise, with BlackRock reportedly purchasing ETH for its iShares Ethereum Trust to generate staking rewards. Additionally, BitMine's Tom Lee has been buying Ethereum, contributing to the growing institutional interest in the asset.

The staking activity suggests that Ethereum is becoming more attractive for long-term holders and institutional investors. However, the actual active staking rate is about 30.8%, not the commonly reported 50%, highlighting a potential discrepancy in staking data. This distinction is important for understanding Ethereum's true economic health and security posture.

The Fusaka Upgrade, launched on December 3, 2025, is a network enhancement aimed at improving scalability and reducing data load. A key feature is PeerDAS (Peer Data Availability Sampling), which helps lower the burden of data on the network and stabilizes transaction fees. The upgrade optimizes Layer 2 (L2) solutions, making transactions cheaper and faster for users while simplifying operations for node runners. By reducing the data load and increasing blob targets, it supports decentralized app growth and strengthens Ethereum's long-term scalability. PeerDAS reduces node bandwidth and storage demands, making the network more accessible for a wider range of participants. This also helps stabilize transaction fees, benefiting users and developers.

The upgrade allows for more efficient data handling without sacrificing security or decentralization. The Fusaka Upgrade is expected to have a significant impact on Layer 2 (L2) solutions, particularly those that rely on Ethereum's infrastructure. By reducing the data load and increasing blob targets, the upgrade makes L2 transactions cheaper and faster. This is especially important for projects that aim to scale Ethereum's capabilities while maintaining low costs and high throughput. L2 solutions like Aztec Network could benefit from the upgrade by leveraging the improved data management to offer more efficient private transactions.
