Ethereum core devs have pushed back the headliner selection deadline for the Glamsterdam meta-EIP, adding two focused review calls and enhanced tracking to ensure each proposal receives thorough technical vetting and stakeholder feedback.

Headliner Decision Delay & Extended Timeline

After closing the proposal window on June 20, organizers realized that several high-impact EIPs required more time for edge-case analysis and community input. The original July 17 decision date has been moved to mid-August, providing authors with ample runway to refine their specifications and address performance concerns before final selection.

Dedicated ACDE Review Sessions

Two new live review calls will be held to facilitate deep dives into each headliner proposal:

  • July 31, 2025 – Initial presentations, benchmark overviews, & proactive Q&A
  • August 14, 2025 – Final spec adjustments, risk mitigations, & voting
    Each author will present their implementation status, share test results, and respond to questions from client teams, researchers, and infrastructure providers.

Real-Time Tracking & PFI Process Strengthening

To boost transparency, the live headliner matrix on forkcast.org now displays each proposal’s scope, impacted components, and PFI/CFI status in real time. Authors must keep entries up to date, and community members can subscribe for notifications on changes.

In response to concerns about EIPs jumping too quickly from Community Feedback (CFI) to Protocol Finalization (PFI), two corrective pull requests have been merged:

  1. Revive EIP-2926 to reintroduce code chunking into the Glamsterdam workflow (#9927) .
  2. Move CFI’d EIPs back to PFI for a thorough pre-finalization review (#9970).

Going forward, teams should base work on the official Glamsterdam Meta-EIP branch, update the PFI queue with CFI-qualified changes, and await headliner selections before merging new code.

Conclusion

By extending the timeline, adding dedicated review sessions, and strengthening the PFI process, the Ethereum community is ensuring that Glamsterdam’s headliner EIPs are battle-tested and community-vetted—setting the stage for a robust, well-tested network upgrade.
