Glamsterdam is the codename for Ethereum's planned network upgrade scheduled for the first half of 2026. Its name is a creative blend of the star "Gloas" and the city of Amsterdam. While previous upgrades like Fusaka focused on expanding data capacity, Glamsterdam's mission is to optimize how the network actually processes your transactions. Think of it as upgrading a single-lane road into a multi-lane highway where many transactions can move at once.
