Glamsterdam Upgrade
◆ Description
Ethereum's Glamsterdam mainnet window opens early December at the earliest, following the testnet upgrades and a roughly 30-day security window. Mainnet is not yet scheduled; the upgrade covers the Gloas consensus and Amsterdam execution upgrades.
◆ Why it matters
The upgrade could materially change Ethereum’s validator workflow and execution capacity through ePBS, Block-Level Access Lists and state repricing. That makes the milestone relevant to ETH’s network-performance and long-term scaling narrative.
