Ethereum developers begin work on Glamsterdam upgrade for H1 2026

Ethereum (ETH) core developers have started preparing for the network's next upgrade, Glamsterdam, which is targeted for release in the first half of 2026, CoinDesk reported. The upgrade aims to improve transparency and decentralization by separating proposers and builders within the protocol, while also enhancing data processing speeds and stabilizing gas fees. The developers are scheduled to resume discussions in January 2026 to finalize the detailed scope of Glamsterdam. Following this, an upgrade named Hegota is planned for the second half of 2026 to address node storage capacity issues.
