Ethereum Foundation Releases Glamsterdam Upgrade Progress: Devnet Launched, Hegotá Expansion Roadmap Advances in Parallel

Odaily reports that the Ethereum Foundation has disclosed the outcomes of a recent interoperability meeting among core developers held in Svalbard, Norway, and provided an update on the key technical progress of the next upgrade phase, "Glamsterdam." During the meeting, multi-client teams collaborated on network scaling and execution layer optimization, making progress in several areas. Developers confirmed that a "credible path" post-Glamsterdam has been agreed upon, based on the combined results of ePBS, BAL optimizations, and the EIP-8037 repricing mechanism.

On the execution layer side, ePBS (External Proposer Separation) has been running stably on the multi-client Glamsterdam-devnet. The external block builder process has completed end-to-end testing, covering nearly all client implementations. Meanwhile, EIP-8037 has been finalized, establishing the fixed cost_per_state_byte model and completing the full repricing parameter output on bal-devnet-6.

The expansion track "Hegotá" has also made progress. FOCIL-related prototypes now have operable implementations. The scope of requirements for Account Abstraction (AA) has been defined, and the next phase will move to multi-client devnet verification. Current development efforts remain focused on the final delivery of Glamsterdam, while simultaneously advancing the Hegotá expansion design and the subsequent Strawmap roadmap evolution. The devnet is now live, and features like FOCIL are expected to be further deepened in the next phase of testing.

At an organizational level, this interop meeting also marked the official start of leadership restructuring within the Protocol Cluster. The new leads include Will Corcoran, Kev Wedderburn, and Fredrik. Will Corcoran will oversee zkVM proofing and post-quantum consensus coordination, Kev Wedderburn will lead zkEVM research and development, and Fredrik will be responsible for protocol security and the Trillion Dollar Security project. Former Protocol Cluster leadership team members Barnabé Monnot and Tim Beiko will gradually step back from management roles, while Alex Stokes is entering a sabbatical cycle. The Foundation stated that during their tenure, the Protocol team successfully advanced modularization and drove the Fusaka upgrade to launch (December 2025), introducing PeerDAS and increasing mainnet gas capacity.
