Woofun AI reports that Ethereum developers have advanced the Glamsterdam upgrade into its final development phase, marking a critical step toward one of the most significant network enhancements since the 2022 Merge. Client teams are currently executing comprehensive tests on private developer networks to validate the complete set of Ethereum Improvement Proposals before transitioning to code hardening and public testnet deployment. While a precise launch date remains unset, the timeline points toward a mainnet activation in the second half of 2026.

The upgrade centers on Enshrined Proposer-Builder Separation (EIP-7732), which integrates block-building functions directly into the protocol to reduce dependency on off-chain relays and enhance transparency in block production.

Concurrently, EIP-7928 introduces Block-Level Access Lists to optimize transaction processing by pre-identifying required account data.

Additionally, gas repricing mechanisms aim to lower costs for high-compute operations while increasing state storage fees, thereby aligning resource consumption with emerging scaling technologies like zero-knowledge proofs.

This shift follows the December 2025 Fusaka upgrade, moving focus from foundational blob capacity to execution efficiency and broader scalability.
