The Glamsterdam upgrade package for the Ethereum network includes changes in throughput, block building, and state pricing, which could reshape user experience, batching operations, and layer-one block builders.

This article explains what will be shipped, how the roadmap targets both capacity and stability, and what that might mean for Ethereum fees, burn mechanisms, and layer-two economics. You will find a clear summary, comparison points, and a practical checklist for decentralized applications and groups preparing for this transition.
