Ethereum Foundation core developer and maintenance engineer Parithosh Jayanthi confirmed on June 17 that the Ethereum Glamsterdam upgrade is currently running on developer networks (devnets) that include all planned EIPs. This is the final stage before the public testnet. Glamsterdam is expected to launch the mainnet in the second half of 2026.
EIP-7732 ePBS: Built-in Proposer-Builder Separation Mechanism
EIP-7732 (ePBS, Enshrined Proposer-Builder Separation) will introduce a separation mechanism between transaction block builders and block proposers into the core Ethereum protocol. At present, this process mainly relies on off-chain mechanisms, which involve additional trust assumptions and centralization issues. After moving it on-chain, developers aim to reduce manipulation opportunities related to maximum extractable value (MEV).
EIP-7928 Block-Level Access List: Preloaded Data for Improved Execution Efficiency
EIP-7928 (Block-Level Access List) allows a block to pre-declare the data of the accounts and smart contract functions it plans to access. This change enables Ethereum client software to load information more efficiently in advance. The goal is to speed up block execution, improve predictability, and make the network easier to optimize.
Gas Repricing Direction: Lower High-Compute Costs, Higher State-Management Costs
Glamsterdam includes comprehensive Gas repricing. Jayanthi confirmed: “This will greatly change the cost of operations on Ethereum. High computational costs will be reduced, while state management costs will increase.” The objective of Gas repricing is to make Ethereum’s fee structure more accurately reflect the resources consumed by different operations, while making the network easier to scale through zero-knowledge proof systems.
The confirmed focus for developers right now is to continue testing, finalize the specifications, and communicate the impact of the repricing changes to the community, before a formal release.
FAQ
When will the Glamsterdam upgrade go live on the mainnet?
According to Jayanthi’s explanation, Glamsterdam is expected to launch the mainnet in the second half of 2026, but “there is no fixed timeline.” It is currently still in the devnet testing stage. After that, the public testnet deployment and testnet hardening still need to be completed before it can go live on the mainnet.
How does ePBS (EIP-7732) reduce MEV manipulation?
According to the article, Ethereum’s block building and proposer separation currently relies on off-chain mechanisms, which come with trust assumptions and centralization risks. EIP-7732 moves this mechanism on-chain (at the protocol layer), reducing reliance on off-chain intermediaries and thereby decreasing manipulation opportunities that may exist during the MEV extraction process.
How will Gas repricing affect Ethereum users and developers?
Based on Jayanthi’s confirmation, the cost of high-computation-volume operations (such as complex computation) will decrease, while the cost of state-management operations (such as storage reads and writes) will increase. This means Gas fees for compute-intensive applications may drop, while applications that frequently read and write on-chain state will need to adapt to higher costs.
