Ethereum’s next major upgrade after Glamsterdam already has a name, a growing list of candidates, and a deadline. The Protocol Cluster, the Ethereum Foundation’s core research coordination team, has published an internal tier list ranking approximately 62 Ethereum Improvement Proposals for the Hegotá upgrade, expected to land sometime in 2027.
Client teams now have until September 10, 2026 to submit their own ranked preferences, which will feed into the final selection process. And for the rest of us who don’t run Ethereum clients for a living, there’s a Reddit AMA scheduled for September 16 where the cluster plans to field community questions about the upgrade’s direction.
What’s on the table
Hegotá follows Glamsterdam, which is slated for Q4 2026 and represents Ethereum’s more immediate priority.
The cluster has been evaluating somewhere between 50 and 66 proposals, with the current ranked set sitting at around 62. Alongside the tier list, the Protocol Cluster produced what it calls a “steelman list,” which documents areas of active disagreement among stakeholders.
