Forecast Trend Report by Period

The Ethereum Foundation disclosed progress on development of “Glamsterdam,” its next network upgrade.

Wu Blockchain reported on May 11 that the foundation carried out upgrade-related testing and preparation during an Interop event recently held in Svalbard, Norway, as part of its May 2026 protocol cluster update.

The foundation said development and validation work on the Glamsterdam upgrade advanced at the event and that key technical milestones were confirmed. It set a post-upgrade target floor for the gas limit at 200M. The ePBS, or proposer-builder separation, architecture has also entered a stabilization phase in a multi-client environment.

EIP-8037 has also been finalized, reshaping the cost structure for state data. Pricing between validators and the execution layer was also adjusted. In the Hecate-related upgrade, requirements for account abstraction, or AA, were further defined, with a multi-client testnet for implementing those features identified as the next step.

The foundation also announced a reorganization of its protocol cluster. Core contributors Barnabé Monnot and Tim Beiko are leaving the foundation, while Alex Stokes is taking a sabbatical.

Will Corcoran, Kev Wedderburn and Fredrik will take over the new leadership roles, according to the report.
