Ethereum developers have advanced the Glamsterdam upgrade into its final devnet stage, with the package now targeting a 200 million gas limit by the second half of 2026. The upgrade has been described as "the largest fork since the Merge" and is aimed at improving network efficiency, Layer 1 scalability and transparency. Earlier expectations in the existing record pointed to a second-half launch this year, but the new timeline centers on a second-half 2026 target for the higher gas-limit objective. The changes could also affect ETH supply dynamics and staking yields, while potentially reshaping maximal extractable value, or MEV, dynamics and competition in block construction on Ethereum.
