Ethereum’s Glamsterdam upgrade was delayed to Q3 2026 as the Foundation set a new 200M gas limit target.
The Ethereum Foundation has confirmed the "Glamsterdam" protocol upgrade is now expected to launch sometime in the third quarter of 2026, having originally targeted June. The delay comes alongside several technical milestones the Foundation disclosed in a Monday blog post.
Among those milestones is the establishment of a 200-million gas limit floor for the post-upgrade network. That figure represents a significant jump from the current gas limit of approximately 60 million, and the Foundation described reaching a "credible post-Glamsterdam target" as a key step forward.
Glamsterdam is designed to scale Ethereum's layer-1 chain by overhauling how the network creates and verifies blocks, reorganizing transaction processing and database management at a fundamental level. Devnets for the upgrade are already live, the Foundation said at an interop event in Svalbard, Norway.
The Foundation also confirmed the stabilization of enshrined Proposer-Builder Separation (ePBS), which integrates block-building separation directly into Ethereum's protocol rules. The change reduces reliance on external relays and gives the network more time to process larger blocks safely.
A separate finalized proposal, EIP-8037, introduces smarter pricing for data storage by raising the cost of state creation operations. The change is intended to prevent excessive state growth under the higher block gas limits that Glamsterdam will enable.
Work on the next major upgrade after Glamsterdam, called Hegotà, is also in progress, with scoping described as "well underway." The Foundation is simultaneously advancing the Strawmap, its quantum-resistant long-term roadmap.
On the leadership side, the Foundation announced a transition for its Protocol cluster. Will Corcoran, Kev Wedderburn, and Fredrik have been named as the new leads. Barnabé Monnot and Tim Beiko are departing the Foundation, while Alex Stokes will take a sabbatical.
"There's a new chapter starting for the Protocol cluster," Corcoran wrote on X on May 11. Monnot, in a separate post, said making Ethereum's unique features more accessible to users remains a priority for him going forward.
