Ethereum's largest-scale upgrade Glamsterdam enters the final development stage, expected to go live in the second half of the year

Deep Tide TechFlow News, June 17th, according to CoinDesk reports, Ethereum core developers have entered the final development stage of the Glamsterdam upgrade, currently running development networks (devnets) that include all planned Ethereum Improvement Proposals (EIPs). After completion, it will be promoted to the public test network. Parithosh Jayanthi, a core developer of the Ethereum Foundation, stated that Glamsterdam "may be the largest fork upgrade since the Merge," which will fundamentally change many of Ethereum's underlying assumptions and lay the groundwork for large-scale future scalability. It is expected to be officially launched in the second half of 2026, but the specific date has not yet been determined.

The core contents of this upgrade include: first, an embedded proposer-builder separation mechanism (ePBS, EIP-7732), which moves off-chain block construction and proposal processes on-chain to reduce MEV-related manipulation risks and centralization concerns; second, block-level access lists (EIP-7928), allowing blocks to declare the accounts and smart contract data they need to access in advance, improving block execution efficiency and predictability; third, a large-scale re-pricing of Gas fees, lowering costs for high-computation operations, increasing state storage costs, to more accurately reflect resource consumption and to be compatible with zero-knowledge proof scaling solutions. Currently, the development team is focused on testing, finalizing standards, and community communication work.
