Ethereum’s Glamsterdam Upgrade Enters Final Stage, Changing ETH Economics
Ethereum’s biggest protocol update in years has moved into its last development stretch. Not the glamorous part. Developers are running devnets for “Glamsterdam,” an upgrade expected in the second half of the year, and the fork has already been described as the biggest since the 2022 Merge. If it ships as planned, transaction costs could change in a way users actually notice, while Ethereum gets prepared for later scaling work. ETH holders should care. My take: network utility is not some abstract developer metric; it is one of the things the market uses when deciding what ETH is worth.
Ethereum developers are testing Glamsterdam on devnets, the final step before hardening and public testnets. Ethereum Foundation core developer Parithosh Jayanthi said teams are running “devnets,” early test environments that include the full set of Ethereum Improvement Proposals planned for the upgrade. He called this the “last phase before we work on hardening and then shipping the testnets” and said the work has made “massive progress.” Sounds close, right? Maybe. There is still no fixed activation date, and that is not a footnote. Ethereum timelines slip. For now, Glamsterdam is expected to go live sometime in the second half of 2024.
Glamsterdam is one of Ethereum’s biggest changes since the 2022 Merge, with scaling and efficiency at the center of it. This is not routine maintenance. Jayanthi called it “probably the largest fork we’ve had since the Merge” and said it could “change a lot of assumptions about Ethereum and set us up for much more scaling in the future.” Strip away the developer phrasing and the market point is blunt: if Ethereum gets cheaper or easier to use, it has a stronger case against other Layer 1 networks. Better scaling could make ETH more useful for decentralized apps. It could also support demand for the asset. ETH has recently traded around $3,000, a sharp rebound from its 2022 lows, so investors are watching for anything that makes that recovery look earned. I’ll be honest: upgrades do not automatically justify price moves, but they can make the bullish argument less flimsy.
The main Glamsterdam proposals include enshrined Proposer-Builder Separation, or ePBS, and Block-level Access Lists. ePBS, tracked as EIP-7732, would move the separation of block building and block proposing into Ethereum’s core protocol. Today, much of that process relies on off-chain systems, which adds trust assumptions and raises centralization concerns. Most upgrade previews say this is mainly about efficiency. That’s only half right. Moving it on-chain should reduce some openings for maximal extractable value, or MEV, manipulation, which is the part institutions and regulators are more likely to understand. MEV has been a standing problem for Ethereum. Regulators and market participants pay attention to it. If Glamsterdam reduces those risks, Ethereum’s case as a decentralized financial network becomes easier to defend, especially with agencies such as the SEC still watching crypto closely.
Block-level Access Lists should make block execution easier to predict, while gas repricings will change what users pay for different actions. Block-level Access Lists, tracked as EIP-7928, let blocks declare in advance which accounts and smart-contract data they plan to access. That may sound minor. It is not. Why does this matter? Because clients can preload data, and preloading can make block execution faster and easier to optimize. Glamsterdam also includes gas repricings, and regular users may actually feel that part. Jayanthi put it bluntly: “This will majorly change the cost of actions on Ethereum. High-level compute gets cheaper and state gets more expensive.” Some dApp interactions may get cheaper. Others may cost more. We have seen this pattern before with fee changes: the headline says “cheaper,” then app-level behavior gets messier. Developers and traders will need to watch the details because a pricing change like this can shift users and fees across Ethereum apps. Money moves.
What this means
Glamsterdam shows Ethereum is still working on the hard parts: scaling, fees, and decentralization. The upgrade targets problems that have frustrated users and developers for years. ePBS deals with block construction and MEV. Gas repricings change the cost of using the chain. Block-level Access Lists make execution more predictable. Counter to the usual advice, I would not treat this as just another “scaling upgrade” headline. None of this is flashy in the meme-coin sense, but Ethereum depends on this kind of plumbing. If the upgrade works, the network could become more usable for large apps and institutional users. That gives ETH a reasonable long term bullish argument, especially while it has held above $3,000 for much of the past month despite wider market swings.
Traders should watch the testnets, the activation date, and the market reaction to gas changes. The next few months matter. Delays or serious testnet problems could hurt ETH sentiment in the short term. A clean testnet run and a firm launch window in the second half of 2024 would give the market a clearer story to trade. Is this overkill for traders who only care about price? No, because the gas repricings could affect the economics of specific dApps, not just Ethereum as an idea. I would watch Ethereum Foundation updates first, then see how major protocols respond. On the chart, a sustained move above $3,500 would suggest traders are buying the upgrade story. Yes, that sounds like a technical trader’s shortcut after several paragraphs of protocol detail. It is. Markets often compress complicated engineering into one ugly price level.
FAQ
Q: What is the Glamsterdam upgrade?
A: Glamsterdam is Ethereum’s next major protocol upgrade. It is in its final development stage and is meant to change transaction costs and improve scaling.
Q: When is the Glamsterdam upgrade expected to go live?
A: Glamsterdam is expected sometime in the second half of 2024, though developers have not announced a fixed date.
Q: What are the main features of Glamsterdam?
A: The main features are enshrined Proposer-Builder Separation, or ePBS, under EIP-7732, Block-level Access Lists under EIP-7928, plus a broad set of gas repricings.
Q: How will Glamsterdam affect transaction costs on Ethereum?
A: Parithosh Jayanthi said Glamsterdam will “majorly change the cost of actions on Ethereum,” with high-level compute becoming cheaper and state becoming more expensive.
Q: What is ePBS, or EIP-7732?
A: ePBS moves the separation of block building and block proposing into Ethereum’s core protocol. The goal is to reduce MEV-related manipulation and rely less on off-chain trust assumptions.
Q: What are Block-level Access Lists, or EIP-7928?
A: Block-level Access Lists let blocks declare in advance which accounts and smart-contract data they plan to access. That should make block execution faster and easier to predict.
Q: Why is Glamsterdam considered a large upgrade?
A: Jayanthi called it “probably the largest fork we’ve had since the Merge” and said it could change assumptions about Ethereum while getting the network ready for more scaling.
Q: What does this upgrade mean for ETH investors?
A: For ETH investors, Glamsterdam is mostly a bet on better network economics. If it improves scaling, fee design, and decentralization, it could support more demand for Ethereum over time.
