Ethereum developers have finalized the roadmap for the much-anticipated Glamsterdam hard fork, scheduled for launch in the second half of 2026. Positioned as one of the most significant changes to the network’s core layer since The Merge, this major update aims to boost Ethereum’s Layer 1 capacity and make the network more efficient for validators, developers, and decentralized applications.
Focus shifts to block validation
According to the Ethereum Foundation, what sets Glamsterdam apart from earlier upgrades is its strong emphasis on overhauling the block validation process. This round of technical preparations brings substantial modifications to both the execution and consensus layers. Prominent crypto analyst Crypto With Gopal also highlights that the network is moving rapidly toward its next phase of scalability.
Among the headline features are EIP 7732, dubbed “Enshrined Proposer Builder Separation,” and EIP 7928, which introduces block-level access lists as central components of the fork.
Glossary: A hard fork refers to a broad protocol change in a blockchain that is not backward-compatible. EIP stands for Ethereum Improvement Proposal, the standard format for discussing suggested technical updates on the network.
Key proposals: EIP 7732 and EIP 7928
EIP 7732 seeks to separate block production from block validation, giving validators a more active protocol-level role in producing blocks. This change is expected to improve network efficiency and reduce reliance on third-party block builders.
EIP 7928, on the other hand, aims to make access lists mandatory at the block level. By doing so, it could accelerate the parallel processing of transactions and potentially drive down gas fees. In essence, gas fees represent the base transaction cost for executing actions or smart contracts on the Ethereum network.
According to the Ethereum Foundation, Glamsterdam is designed to expand Layer 1 capacity and create a more favorable environment for validators, developers, and decentralized applications on the network.
A new batch of EIPs readies for devnet testing
Developers are planning to include ten new EIPs in the next devnet release. Among the approved proposals are EIP 7708, which introduces a new structure for ETH transfer logs, and EIP 7954, expanding the smart contract size limit from 24 KiB to 64 KiB.
Additional improvements in the pipeline involve enhancements to gas measurement, call data management, opcode sets, and state control mechanisms. Meanwhile, another fifteen EIPs focusing on gas fees, validator architecture, network communication, and staking are still under evaluation. It appears EIP 7904 is unlikely to be accepted.
| Title | Status | Key Impact |
| EIP 7732 | Planned | Separation of block production and validation |
| EIP 7928 | Planned | Faster processing and lower costs |
| EIP 7708 | Approved | Defines ETH transfer record structure |
| EIP 7954 | Approved | Raises smart contract size limit to 64 KiB |
Potential impact on developers, validators, and users
The updated roadmap reveals Ethereum’s ongoing adaptation to its accelerating pace of use and application development. For developers, the proposed changes could simplify the deployment process and trim costs. Validators may benefit from faster block production, while end-users could enjoy a more balanced and predictable fee structure as a direct consequence of the upgrade.
While Glamsterdam signals Ethereum’s commitment to a post-Merge future, it also underlines the network’s goal of achieving higher efficiency and broader scalability across its foundational infrastructure.
With more than a year to go until the full deployment of the upgrade, the current roadmap demonstrates which technical priorities Ethereum is set to tackle next. Notably, proposed changes to block validation sit at the very heart of the network’s long-term roadmap for scaling up its capabilities.
