Ethereum's Glamsterdam Upgrade Takes Shape as Key Milestones Approach

The Ethereum Foundation's next major upgrade, 'Glamsterdam', is nearing completion. According to Tony Warshtetter, an Ethereum researcher, Glamsterdam and EIP-7928 are in their final stages of development.

Testing continues on a developer network (devnet), with the first public test, the Sepolia fork, scheduled for October 6. The mainnet application is expected in the fourth quarter of 2026, although an exact date has not been disclosed.

Glamsterdam aims to improve Ethereum's processing speed, expand its network capacity, and reduce database bloat. Key features include block-level access lists (EIP-7928) for enhanced parallel processing, as well as ePBS (Efficient Block Proposal Structure), which revises block validation procedures to reduce trust assumptions.

Ethereum co-founder Vitalik Buterin has outlined a long-term roadmap called 'Strawman', which includes recursive STARK, automated formal verification, and advanced consensus algorithms for quantum resistance. He suggests that Glamsterdam is a major turning point in Ethereum's evolution, paving the way for a structural transition towards a high-security computing environment.
