Ethereum's Glamsterdam Upgrade Enters Final Devnet Phase With 200M Gas-Limit Target

§ 01 Executive Snapshot

• What: Ethereum's Glamsterdam Upgrade has entered its final development phase, focusing on enhancing network capacity.
• Who: Ethereum Foundation developers and core contributors.
• Why it matters: This upgrade is poised to significantly increase Ethereum's transaction throughput, addressing scalability challenges and improving user experience.

§ 02 Key Developments

• The upgrade will implement ten Ethereum Improvement Proposals (EIPs) including EIP-7732 for Proposer-Builder Separation and EIP-7928 for Block-Level Access Lists.
• The target gas limit is set at 200 million, which is expected to triple Ethereum's current Layer 1 capacity from around 60 million.
• The upgrade is projected to enable up to 10,000 transactions per second (TPS) under realistic workload conditions.

§ 03 Strategic Context

• The Glamsterdam upgrade is framed as the largest protocol change since the Merge, indicating its critical role in Ethereum's evolution.
• Previous debates among developers about the feasibility of shipping ePBS and BALs together reflect the upgrade's ambitious nature in addressing scalability.

§ 04 Strategic Implications

• Immediate implications include increased transaction throughput and reduced transaction costs for end users, enhancing Ethereum's competitive position in the blockchain space.
• Long-term implications involve the potential for Ethereum to better support Layer 2 solutions and decentralized applications, driving broader adoption.

§ 05 Risks & Constraints

• Potential risks include the need for validators to adapt to new processes and the uncertainty around maintaining network stability during the transition to higher gas limits.
• Competition from other blockchains that may offer better scalability solutions could pose challenges to Ethereum's market position.

§ 06 Watchlist / Forward Signals

• Key upcoming milestones include the public testnet phase following successful devnet rotation, expected to occur in late 2026.
• The activation date for the mainnet will be determined post-testnet stability, with a projected launch window between September and December 2026.
