Ethereum Enters Final Development Phase for Glamsterdam Upgrade
CIE News ·
The Ethereum network has officially entered the final development phase for its upcoming Glamsterdam upgrade, a significant technical milestone aimed at enhancing core network throughput. The upgrade centers on the implementation of EIP-7928, a proposal designed to introduce block-level access lists, which will fundamentally restructure how the network manages and validates data. As the project transitions into this concluding development stage, developers have confirmed that a rigorous testing schedule is now in place to ensure stability before the anticipated mainnet rollout in Q4 2026. This deployment marks a pivotal moment for the Ethereum ecosystem as it continues to focus on long-term scalability and efficiency improvements. The first critical test is scheduled to occur on the Sepolia testnet on October 6, 2026, serving as a primary proving ground for the new code before the broader production launch. The core technical mechanism behind the Glamsterdam upgrade is the introduction of block-level access lists alongside the deployment of 'snap v2'. This combination is engineered to facilitate greater processing speeds through increased parallelism while simultaneously optimizing network synchronization. By streamlining these synchronization processes, the upgrade is expected to directly expand Ethereum's throughput capacity, addressing ongoing network performance demands. With the Sepolia testnet trial serving as the immediate next step, the Ethereum development community is prioritizing a stable transition. Following the October 6 evaluation, findings from the testnet will be scrutinized to refine the final configurations ahead of the Q4 2026 mainnet deployment. Current development efforts remain focused on validating the implementation of EIP-7928 to ensure it meets the established benchmarks for network optimization and synchronization reliability.
