This was followed by client implementation, where developers integrated the agreed-upon changes into their respective client software.
The subsequent phase, exemplified by the Svalbard interop, is dedicated to rigorous testing and refinement. This includes:
- Devnets: The launch of development networks where specific features of Glamsterdam are tested in a controlled environment. These devnets allow for early identification of bugs and performance issues. The article notes that Glamsterdam devnets are currently live, indicating this phase is well underway.
- Testnets: Larger, more public test networks that mimic mainnet conditions more closely. Here, the community at large can participate in testing, providing valuable feedback and stress-testing the network.
- Interop Events: Like the one in Svalbard, these focused gatherings bring together core developers to synchronize efforts, resolve cross-client compatibility issues, and ensure a unified approach to implementation and deployment.
- Mainnet Launch: The final deployment of the upgrade to the live Ethereum network.
The article also points to the ongoing preparation for “Hegotã,” the upgrade following Glamsterdam, with FOCIL slated for inclusion on the consensus layer side. This demonstrates Ethereum’s commitment to a forward-looking roadmap, ensuring continuous improvement and the introduction of new capabilities. The mention of FOCIL suggests a focus on enhancing the consensus mechanism, potentially related to further decentralization, security, or efficiency.
Team Evolution: A New Chapter for the Protocol Cluster
A significant outcome of the Svalbard interop was the formal commencement of a leadership transition within the Ethereum Foundation’s Protocol cluster. This cluster plays a pivotal role in coordinating and driving the core protocol development efforts, which are fundamental to the network’s evolution and security.
For the past year, since the announcement of the Protocol Cluster, Barnabé Monnot, Tim Beiko, and Alex Stokes have been instrumental in its formation and operation. Their collective leadership has been credited with launching crucial initiative tracks and overseeing the successful deployment of the “Fusaka” upgrade in December 2025. Fusaka’s impact was substantial, introducing PeerDAS (a data availability sampling mechanism) and increasing the mainnet gas limit, a move that signaled a strategic push towards accommodating higher transaction volumes and paving the way for future scalability solutions aiming for a 200 million gas limit.
The article acknowledges the immense contributions of Barnabé, Tim, and Alex. Barnabé and Tim are soon departing the Ethereum Foundation, while Alex Stokes will be commencing a sabbatical.
