Why is Ethereum (CRYPTO) testing the Glamsterdam upgrade?

Ethereum (CRYPTO) developers are testing the Glamsterdam upgrade to validate all planned protocol changes before public deployment. The current development phase uses private developer networks containing the full set of proposed Ethereum Improvement Proposals.

What is Enshrined Proposer-Builder Separation for Ethereum (CRYPTO)?

Enshrined Proposer-Builder Separation, or EIP-7732, is a proposed Ethereum (CRYPTO) upgrade that separates block builders from block proposers within the protocol. Developers say the change is intended to reduce reliance on offchain systems and address concerns around maximal extractable value.

How will Block-level Access Lists affect Ethereum (CRYPTO)?

Block-level Access Lists, or EIP-7928, would allow Ethereum (CRYPTO) blocks to specify in advance which accounts and smart-contract data will be accessed. Developers say this could improve execution efficiency and make block processing more predictable.

What do the proposed gas repricing changes mean for Ethereum (CRYPTO)?

Ethereum (CRYPTO) developers said Glamsterdam includes gas repricing changes designed to better reflect the resources consumed by different network operations. The proposal is also intended to improve Ethereum's compatibility with future scaling technologies, including zero-knowledge proving systems.

When is the Ethereum (CRYPTO) Glamsterdam upgrade expected to launch?

Ethereum (CRYPTO) developers have not set a final activation date for Glamsterdam. The upgrade is currently expected to go live during the second half of the year after testing, specification reviews and public testnet deployment are completed.

Ethereum (CRYPTO:ETH) developers have entered the final development stage of the Glamsterdam network upgrade.
The upgrade includes major protocol changes designed to improve scalability, efficiency and block production.
Developers are now testing all planned proposals before moving the upgrade to public test networks.

Ethereum (CRYPTO:ETH) developers have entered the final development phase of the Glamsterdam upgrade, with teams running private developer networks that include all planned protocol changes.

The milestone comes ahead of public testnet deployment and follows months of work on what developers describe as one of Ethereum's largest upgrades since its transition to proof-of-stake in 2022.

“We're working on devnets with all the EIPs in them right now,” said Ethereum Foundation devops engineer and core developer Parithosh Jayanthi.

The upgrade includes Enshrined Proposer-Builder Separation (EIP-7732), Block-level Access Lists (EIP-7928) and a series of gas repricing changes that developers say are intended to improve network efficiency and scalability.

Developers are continuing testing, specification reviews and community outreach regarding the proposed fee structure changes, while Glamsterdam is currently expected to be activated during the second half of the year; following the update the Ethereum price reaction was not disclosed.

Jayanthi described Glamsterdam as one of Ethereum's largest protocol upgrades since the Merge, with proposed changes that could alter how transaction blocks are built and processed across the network.

The upgrade is also designed to improve Ethereum's compatibility with future scaling technologies, including zero-knowledge proving systems, while making transaction execution more predictable and resource allocation more efficient.

At the time of reporting, Ethereum price was $1,795.80.
