Ethereum has completed the Fusaka upgrade and begun its journey towards Glamsterdam by 2026. This upgrade promises to optimize blockchain scalability and strengthen censorship resistance.
The Ethereum network has just overcome one of its most complex technical stages with the operational activation of Fusaka in early December. However, in the fast-paced ecosystem of digital finance, the present becomes history with unprecedented speed.
While users and second-layer protocols are beginning to see reduced costs and smoother transactions thanks to Fusaka's recently implemented improvements, core developers have already set their sights on the next timeframe. The name now echoing in governance forums, code repositories, and planning sessions is... Glamsterdam, an update tentatively scheduled for the first half of 2026 which promises to redefine the internal architecture of the protocol beyond mere speed.
Ethereum's development cycle maintains a relentless pace, striving to balance immediate market needs with long-term security. While recent focus has been almost exclusively on the ability to process massive amounts of data to decongest the network, the new roadmap suggests a shift in priorities. Blockchain engineers are now aiming to strengthen the neutrality of the system and modernize its foundationsensuring that the infrastructure can support a global economy without relying on trusted intermediaries.

The merging of updates Feather in the consensus layer and Osaka The implementation at the execution layer gave rise to what the market and technical community know as Fusaka. This implementation was a direct response to a critical demand for greater processing capacity. With the introduction of peer-to-peer data availability sampling, technically known as PeerDASThe Ethereum ecosystem has multiplied the resources available for scaling solutions.
This technical advancement is translating into real and tangible blockchain scalability. Network fees have begun to decrease, by allowing the blockchain to process large volumes of information, packaged in "blobs", without overloading the validator nodes that maintain its security.
In other words, Fusaka is keeping its promise to alleviate congestionThis has allowed Layer 2 networks to operate with unprecedented efficiency margins. However, its success has primarily paved the way for deeper challenges that extend beyond gas prices and into the realm of network sovereignty.
With the successful activation of Fusaka, Ethereum developers have completed a phase dedicated to increasing the network's capacity in quantitative terms. And now that the digital infrastructure is supporting greater traffic, attention is shifting to who manages and validates the information circulating on this digital highway. The focus is therefore moving towards optimizing the structure and strengthening censorship resistance, aspects that will be at the heart of the next evolution in blockchain technology.
Opera ETH: scalability is real after FusakaEthereum's next big upgrade: Glamsterdam
The Ethereum developer community's focus is now on the second quarter of 2026, the estimated date for the arrival of Glamsterdam. This name comes from combining Glosses, the name of a star assigned to the consensus layer, and the city of Amsterdam, venue for important developer meetings, for the execution layer.
Unlike its predecessor, this new Ethereum update seeks to protect the infrastructure against centralization and eliminate external dependencies that could compromise network integrity.
The critical point of this new stage It lies in the separation between block proponents and builders inscribed directly in the protocol, a technical feature called ePBSTo date, validators have relied on external intermediaries and repeaters to organize transactions in the most cost-effective way possible. This dynamic has created points of centralization vulnerable to external pressures.
However, with the arrival of Glamsterdam, this dependency will be eliminated by integrating the block building process directly into Ethereum's codebase. The goal of this upcoming upgrade is to strengthen censorship resistance and ensure network neutrality, allowing any stakeholder to participate in block validation and security without relying on sophisticated third parties.
In addition to censorship resistance, profound modernizations of the data structure are planned through the implementation of SSZ at the runtime layer. This technical change, while invisible to the average user, lightens the verification load and modernizes the format of internal data. At the same time, Glamsterdam is expected to include significant improvements to the account abstractionThis would facilitate the use of smart wallets, eliminating the need to manage complex recovery phrases and bringing the cryptocurrency user experience closer to the simplicity of traditional banking applications.

The timeline set by Ethereum's development coordinators suggests that Glamsterdam implementation testing on testnets will begin in the first few months of next year, with the goal of bringing these changes to the main network by mid-2026.
Overall, the transition from the data efficiency brought by Fusaka to the structural robustness of Glamsterdam demonstrates a technical maturity in the project. It's no longer just about making transactions cheaper, but about ensuring a solid foundation for the decentralized economy.
Developers are working to ensure this technical evolution occurs seamlessly for the end user, but with a clear impact on the security and sovereignty of their operations. Thus, while the market absorbs current improvements, the code that will define the future of the network is already being written, confirming that innovation in this sector is a continuous process that waits for no one.
