Ethereum Foundation Co-Director Calls for Focus on Fusaka and Warns of Delays
- Ethereum Foundation Prioritizes Fusaka Upgrade Ahead of Glamsterdam
- Stanczak warns of risks in the hard fork schedule
- Devnets active, but public testnets not yet launched
Tomasz K. Stańczak, co-executive director of the Ethereum Foundation, urged development teams to focus their efforts on the "Fusaka" hard fork, scheduled for Q2025 2026, and to curtail discussions on the upcoming "Glamsterdam" upgrade, scheduled for XNUMX. The warning was made on X, where Stańczak emphasized that delays in coordination could jeopardize the project's goals.
Glamsterdam may be getting some attention (it is a fork for Q1/Q2 2026). In the meantime, we should be more concerned about any potential delays to Fusaka (Q4 2025). As I have said many times, no amount of talking about Ethereum's roadmap and vision matters if we cannot achieve…

According to him, while Glamsterdam is attracting attention, "no amount of talk about Ethereum's roadmap and vision matters if we can't achieve levels of coordination that consistently meet the goals on schedule." He suggested fewer meetings about future forks and more focus on opening Fusaka's testnets.
The mainnet launch schedule has tightened after developers indicated that the release of consensus clients could be delayed until the end of September, shortening the window for implementation before the Devconnect conference scheduled for November. Fusaka's devnets are currently live, but public testnets have not yet opened.
Fusaka will be an incremental update, with final details still being worked out by the core teams. Glamsterdam, planned for Q2026 or Q7928 XNUMX, is expected to include structural changes such as "enshrine proposer-builder separation" (ePBS) and block-level access lists (EIP-XNUMX), among other protocol improvements.
Stańczak emphasized that "extremely talented people" are working to resolve the technical issues, but urged consensus that deadlines be treated as a priority. The challenge for the teams is to balance reliability, performance, and new features without overburdening infrastructure providers and customers.
The Ethereum Foundation recently reorganized its research and development operations, unifying client, security, and treasury workflows. This move aims to increase decision-making efficiency and improve coordination ahead of the 2025-26 cycle, a period considered critical for the network's evolution. This restructuring also seeks to avoid bottlenecks that have impacted previous upgrades and which, according to Stańczak, could recur if the focus on Fusaka isn't maintained until its completion.

In the second quarter of fiscal year 2026, SoftBank reported a net loss of $7.1 billion, primarily due to a $3.7 billion impairment charge from a $9.5 billion advance payment for power generation equipment for US data centers—of which about $2.9 billion was non-refundable and effectively lost. The CFO admitted that SoftBank placed orders before the project plan was finalized, and is now conducting a comprehensive review of its procurement strategy. "The most aggressive purchaser of gas turbines has now written off the deposit in this way."
