The Story of "Glamsterdam"

Did you know the name "Glamsterdam" comes from combining the star Gloss with the Devconnect city Amsterdam? It’s the proposed Execution Layer (EL) upgrade following Fusaka. Curious about how Ethereum upgrades get their names? Check out this insightful video: How Are Ethereum Upgrades Named.

Past CL upgrades have been named after stars like Altair, Bellatrix, Cancun, Deneb, Electra, and Fulu. For G-star, you can follow alternative suhhested here: Ethereum Magicians Discussion.

Traditionally, Ethereum upgrades were named after Devcon cities. However, this time around, Andrew B Coathup mentioned that this cross-layer upgrade will be combined with a city where last Devconnect took place - "Amsterdam". It’s worth noting there’s already a Meta EIP for this (EIP-7773: Hardfork Meta - Amsterdam).

With Devcon now being a biennial event, using Devconnect city names could make sense for annual upgrades. Still, does the name "Glamsterdam" really fit? It’s currently a front-runner, but not everyone loves it. Could there be better alternatives? Let’s dive into some creative options!

Pectra: A Sneak Peek Into What’s Coming

First up, Pectra (Prague + Electra) gave us a solid foundation with some key improvements. But here’s the thing—two big features, PeerDAS and EOF (EVM Object Format), were set aside for the next upgrade.

So, if you missed it, you can catch up by checking out some of the details about Pectra in my previous post. It covered a lot, but the big focus now is Fusaka.

Fusaka: What’s After Pectra?

Enter **Fusaka**, named after the cities *Fulu* and *Osaka*, which brings in the features that were moved from *Pectra*. Let’s dive into them:

  1. PeerDAS (Data Availability Sampling)
    PeerDAS is a game-changer for how Ethereum handles data. Instead of downloading every single blob of data, nodes will now only store a small sample and check in periodically to verify it. This will allow the network to process more data (throughput) while keeping the bandwidth requirements the same. Cool, right? If you want the details, Francesco’s Devcon SEA talk covers it all.

  2. EOF (EVM Object Format)
    EOF is about improving the Ethereum Virtual Machine (EVM) itself. It gives Ethereum’s bytecode a makeover to make it more efficient and easier to analyze. By removing some unnecessary features, it helps ensure that contracts are more secure and easier to verify. Danno Ferrin’s talk at Devcon SEA is a must-watch if you’re curious!

Both of these are still being tested on independent devnets, but once Pectra goes live, Fusaka’s devnet will bring them together, and that’s when the magic happens.

Glamsterdam 🪩: The G-Star Name for Ethereum’s Next Consensus Layer Upgrade

Here’s the fun part: after Fusaka, we’re looking at the Amsterdam upgrade, which will involve a major transition from Merkle trees to Verkle trees.

Other G-Star Names on the Table

While Glamsterdam is getting a lot of attention, there are several other G-star names that could also fit the bill for Ethereum’s next consensus layer upgrade. Here are some of the options:

  • Gacrux

    • A stunning name from the southern hemisphere, Gacrux is part of the constellation Crux. It has a nice ring to it and could certainly serve as a strong contender for Ethereum’s upgrade.

  • Gienah

    • Another beautiful star name, Gienah is located in the constellation Corvus. It has a mysterious, yet approachable vibe to it—perfect for Ethereum's next phase.

  • Geminga

    • A bit more on the scientific side, Geminga is a gamma-ray pulsar. It’s a name that carries a lot of energy—quite fitting for an upgrade designed to inject speed and efficiency into Ethereum.

  • Gomeisa

    • Gomeisa is a bright star in the constellation Canis Minor, and its name has a certain elegance to it that could work perfectly for a transformative Ethereum upgrade.

  • Garnet Star

    • A unique and deep red star, the Garnet Star brings with it a sense of rarity and strength. It could be an excellent option to symbolize a major shift in Ethereum’s infrastructure.


The community has already started casting their votes, with Glamsterdam leading the charge, but other names like Gacrux and Gienah are still in the running. Voting is open, and it’s a great chance for everyone to have a say in what the next big upgrade will be called.

So, What’s Next?

Ethereum’s next consensus layer upgrade will mark a significant milestone in the network’s evolution. The transition to Verkle trees will improve how Ethereum stores data and validates transactions, setting the stage for even greater scalability and efficiency.

And as for the name? Glamsterdam is more than just a name; it’s a representation of the exciting times ahead for Ethereum.

Stay tuned for more updates, and don't forget to cast your vote if you haven’t already!
