The Glamsterdam update has now reached its final stage of development. Private developers are testing all the Ethereum Improvement Proposals.
You can read more about it here:
- Ethereum developers will test the Glamsterdam developer networks with all EIPs planned before the start of public testing.
- This upgrade focuses on ePBSs and block-level access lists to increase Layer 1 scaling capability.
- Glamsterdam changes the price of gas, making computation cheaper and state storage prices rising for developers.
CoinDesk reported The teams have created developer networks with all EIPs for forks. It is important to complete the work before code hardening and public testnet deployment.
The testnets are currently in a phase where clients can test the behavior of Glamsterdam across all upgrade packages before they go live. Ethereum Foundation’s Parithosh Jaanthi stated that teams are currently working on developing devnets. “all the EIPs in them right now.”
Jayanthi has also stated that. “no fixed timeline,” But developers have created “massive progress.” Although the upgrade will still be expected to occur in 2026’s second half, final timing is dependent on client readiness and testnet results.
Glamsterdam upgrade centres on ePBS access list and ePBS
Glamsterdam’s two major proposals are Enshrined Block Builder-Proposer Separation or ePBS. ePBS (listed as EIP-7732) moves the separation between block builders, block proposers, and Ethereum’s core protocols.
The change will reduce trust in relays off the chain and increase block transparency. The change also targets the risks associated with maximising value extraction, when transaction order can lead to unfair trading results for users.
Each block can show, in advance, which data and accounts it intends to use with Block-Level access Lists. It gives the client a more clear map of what to expect before execution starts.
It is a goal to speed up block processing and make it easier to optimize. Ethereum.org states that BALs allow nodes to pre-load transactions, and then process them in parallel if they are not touching the same state.
The gas repricing is another layer.
Glamsterdam will also include changes in gas prices. Jayanthi says the updated will “change the cost of actions on Ethereum,” Adding that “high-level compute gets cheaper and state gets more expensive.”
This change is intended to better align the fees with resources consumed by various operations. This could affect how contract designers design their contracts, particularly when large quantities of data are created or read by apps.
Crypto.news has previously published a report on this. Ethereum’s 2026 roadmap placed Glamsterdam and Hegotá after earlier upgrades such as Pectra and Fusaka. These upgrades were focused on the performance of validators, data capacities, and wider scaling.
Crypto.news reported Fusaka’s initial testnet deployment centered around PeerDAS and blob capacity. Glamsterdam focuses on Layer 1 and Block Production Changes.
Glamsterdam: What changes?
Glamsterdam will be Ethereum’s next hard fork. This hard fork combines both consensus and execution layer updates. Its name blends Gloas with Amsterdam.
Regular ETH users should be able to upgrade their wallets and balances without any issues. Installing updated software for node operators and validators is required before activating the mainnet.
It does not add a single feature. The upgrade changes the way Ethereum creates blocks, executes data, and charges some network actions.
Jayanthi described Glamsterdam as “probably the largest fork we’ve had since the Merge.” If the testing is stable, developers will move on to public testnets before setting a schedule for mainnets.
