Fact Check
Multiple independent sources dated June 16, 2026 confirm all elements of the claim. CoinDesk and CryptoBriefing report Glamsterdam entering its final development phase with devnets running all planned EIPs as a step before public testnets, and a mainnet launch targeted for H2 2026. The official Ethereum Foundation blog (Checkpoint #9) corroborates the development pipeline structure (devnets before testnets before mainnet). The claim text matches these sources precisely.
Summary

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.

Terms & Concepts
  • gas limit: The cap on the total amount of computational work that transactions in a block can consume.
  • MEV: Maximal extractable value, or the profit that can be captured by controlling transaction ordering within blocks.
  • staking yields: Returns earned by token holders who lock assets to help secure a proof-of-stake network.
