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.

The S&P 500 has experienced intraday fluctuations of less than 1% for 27 consecutive trading days, marking the longest period of low volatility since the pandemic. Goldman Sachs warns that this "calm" is the result of zero-day options strategies forcibly locking in the market, and once a catalyst emerges, the compressed volatility energy will be released all at once.

Especially before energy shocks and the significantly eased large-scale expansion of the US fiscal deficit, the conditions to quickly replicate the sharp yield decline seen at the end of 2023 are not yet fully in place.
