ETH<\/a>) external proposer-builder separation architecture \u2014 is now running stably on a multi\u2011client Glamsterdam devnet. The external block builder process has completed end\u2011to\u2011end testing and currently covers \u201calmost all client implementations,\u201d allowing separate builder processes to assemble blocks while proposers focus on consensus, a key step in formalizing the MEV supply chain at the protocol level.<\/p>\nDevelopers also confirmed that EIP\u20118037, which increases the gas cost of state creation, has reached its final draft and is now parameterized in the bal\u2011devnet\u20116 test network. The proposal introduces a fixed cost_per_state_byte model designed to target state growth around 60 GiB per year at a 300 million gas block limit, with contract deployment costs rising roughly 10x and new account creation about 8.5x, while maintaining separate metering for code deposit so large contracts like Uniswap pools remain deployable. According to the Foundation\u2019s summary, the combined results of ePBS, BAL optimization work and EIP\u20118037 repricing have given client teams a \u201ctrusted path\u201d for Glamsterdam\u2019s final scope.<\/p>\n

Hegot\u00e1, FOCIL and the post\u2011Glamsterdam roadmap<\/h2>\n
Scalability and censorship\u2011resistance features originally slated for Glamsterdam are now explicitly part of Hegot\u00e1, Ethereum\u2019s second major 2026 upgrade. The update notes that the FOCIL (Fork-choice Inclusion Lists) prototype has a runnable implementation and that the scope of account abstraction (AA) requirements for Hegot\u00e1 has been defined, with the next phase entering a multi\u2011client devnet validation stage. Earlier communications from the Foundation and ecosystem contributors explained that FOCIL was moved out of Glamsterdam to avoid delaying the fork and to keep scope within a manageable envelope; Hegot\u00e1 will also introduce Verkle Trees to cut node storage requirements by up to 90% and pave the way for stateless clients.<\/p>\n
Current development focus, the blog says, remains on \u201cfinalizing Glamsterdam\u2019s implementation\u201d while continuing to advance Hegot\u00e1\u2019s design and the subsequent Strawmap route evolution for longer\u2011term roadmap items. The Glamsterdam mainnet activation is still targeted for the first half of 2026 \u2014 with Q3 now seen as more realistic by some commentators after the Sold\u00f8gn interop devnet wrapped up in early May \u2014 while Hegot\u00e1 is positioned as a late\u20112026 \u201ccleanup and optimization\u201d fork that addresses technical debt in Ethereum\u2019s data structures.<\/p>\n
Leadership changes in Ethereum\u2019s Protocol Cluster<\/h2>\n
Beyond code, the Svalbard interop meeting also marked a formal leadership reshuffle inside the Foundation\u2019s Protocol Cluster. The update names three new leaders: Will Corcoran, who will coordinate zkVM proofs and post\u2011quantum consensus research; Kev Wedderburn, who will lead zkEVM development; and Fredrik, tasked with protocol security and the \u201cTrillion Dollar Security\u201d initiative.<\/p>\n
<\/p>\n
Original Protocol Cluster leads Barnab\u00e9 Monnot and Tim Beiko will gradually step back from management roles, while long\u2011time researcher Alex Stokes is entering a leave period. The Foundation notes that under the outgoing structure, the protocol group \u201ccompleted modular advancement\u201d and delivered the Fusaka upgrade in December 2025, which introduced PeerDAS to boost data availability and enabled a mainnet gas capacity increase that set the stage for Glamsterdam and Hegot\u00e1.<\/p>\n
The post ends with a familiar caveat: timelines remain subject to change based on testnet results, and users are reminded that upgrade\u2011related volatility \u2014 in fees, MEV flows or client behavior \u2014 carries risk even when the development roadmap looks orderly on paper.<\/p>\n
