The early months of 2026 prompted the Ethereum community to engage in some significant self-reflection. This period went beyond just analyzing price shifts and technical enhancements; it raised critical questions about the network’s future identity.
Even prior to this year, many in the Ethereum landscape sensed that the network was on the brink of a new growth phase. This would be characterized not by crypto enthusiasts but rather by institutions leveraging advanced technology. Some speculate that neobanks could easily onboard millions of users by simplifying the experience—essentially removing the hassle of wallets and gas fees. In this scenario, Ethereum doesn’t need to attract users directly; instead, it acts as the underlying infrastructure empowering a revamped financial ecosystem that looks quite different from traditional cryptocurrencies.
This perspective is rooted in a long-held belief that Ethereum’s strength lies in its elusive qualities.
Years of user experience upgrades and cost reductions have shaped this vision. For example, the “proto-dunksharding” introduced in the Dencun upgrade has significantly decreased Layer 2 transaction costs by enhancing data download capabilities, while improvements to the base layer have fostered more efficient transactions.
Although the market has influenced the price of Ether (ETH) tokens, these upgrades are steering Ethereum toward a paradigm where users can navigate applications without deeply understanding the underlying tech.
Yet, this optimistic narrative began to shift just a few weeks into the year, as focus turned back to the foundational roadmap.
L2 discussion
At the start of the year, co-founder Vitalik Buterin offered a candid reality check to the ecosystem: “You’re not scaling Ethereum.”
This remark disrupted a previously celebratory discussion around rollups—Layer 2 (L2) networks designed to process Ethereum transactions more efficiently by bundling them back into the main chain. While L2 networks have surged in popularity, with decreasing transaction fees and increasing activity, the crucial question remained whether they truly represented significant scaling.
Buterin’s critique went deeper than general concerns; he argued that many existing L2 designs were straying from Ethereum’s foundational principles, leaning on centralized elements and isolated environments that fail to uphold the base chain’s assurances. The worry was less about the existence of L2 solutions and more about their ability to achieve the scaling Ethereum aspires to.
This criticism seemed to amplify existing anxieties.
The issues of L2-to-L2 fragmentation, uneven security assumptions, and dependence on centralized components began to resemble structural threats rather than mere temporary adjustments. In seeking to expand, Ethereum risked forfeiting the very qualities that made it valuable: robust security, decentralization, and a unified payments layer that allows for seamless application and liquidity interconnectivity.
The L2 community didn’t resist this call for change sufficiently. Some recognized the critique and leaned toward a vision where rollups evolve to specialize in areas like privacy and consumer-facing applications, alongside offering their own execution environments. Meanwhile, others staunchly defended their role, positing that high-throughput environments are still essential.
On the other hand, Ethereum’s base layer continues to progress gradually. Upgrades like December’s Fusaka hard fork have enhanced both the data capacity and efficiency of the main network, allowing it to handle more transactions at reduced costs. Recently, however, a spike in transaction activity has attracted scrutiny, with some labeling it an “address poisoning” scheme.
This tension highlights how Ethereum’s pathway forward necessitates a careful balancing act between structural upgrades on the base layer and the emergence of specialized rollups that can enhance the ecosystem without jeopardizing core security.
According to 21shares, this could lead to a more integrated approach among Layer 2 networks. “We expect to see Ethereum’s L2 integration, a more streamlined and resilient layer aligned with ETH, supported by high-performance exchange-backed networks,” the firm noted in a research report.
Quantum threat
Concurrently, another long-discussed but previously lower-priority issue has suddenly gained urgency: quantum computing.
The Ethereum Foundation has signaled a shift in its approach, endorsing projects like “LeanVM” and post-quantum signature schemes. What once seemed like a distant concern is now being factored into short-term planning.
This newfound focus cannot be overlooked. Networks must now be built with not only the next cycle in mind but also with potential threats that could compromise encryption fundamentals. The foundation has acknowledged this risk and launched dedicated research efforts centered on post-quantum security.
Buterin has also sketched out a roadmap aimed at safeguarding blockchain against long-term risks posed by quantum advancements.
Internal shuffle
If the scaling debate uncovered vulnerabilities in Ethereum’s current framework, the looming risks from quantum technology have raised further questions about its future, and the network seems to be taking these concerns seriously.
Intriguingly, this change is coming from within.
The resignation of Tomasz Stanczak as co-executive director of the Ethereum Foundation represents more than just a leadership shift. In a period when networks are grappling with technical, strategic, and philosophical reevaluations, even subtle leadership changes can signal broader adjustments.
This development was unexpected.
The foundation has not typically been known for abrupt changes, and Stanczak’s appointment was relatively recent, following a lengthy tenure by Aya Miyaguchi. In an ecosystem that tends to prioritize consistency, this swift change hints at a more profound internal transformation, responding to the growing pressures centered on Ethereum’s roles in scaling, security, and artificial intelligence (AI).
“Trust layer”
Speaking of AI—a subject that’s become crucial not only in crypto but across all sectors—it’s starting to inspire a new perspective on networking.
Buterin articulated how Ethereum could be pivotal to the future of artificial intelligence. This notion extends beyond mere payments and DeFi, envisioning Ethereum as a coordinating layer for decentralized AI systems, facilitating verifiable outputs, trustworthy data sharing, and economic interactions among machines.
This momentum didn’t develop overnight.
The Foundation initiated a dedicated Decentralized AI Research Unit (dAI) early last year, tasked with exploring how networks can support autonomous agents and facilitate a machine-to-machine economy. What began as an experimental endeavor has evolved into a more structured approach by 2026, with a growing perspective that frames Ethereum as a potential “layer of trust” for AI, validating outputs, coordinating activities, and anchoring a rapidly evolving ecosystem dominated by centralized players.
All these ambitious expansions position Ethereum at the intersection of two of today’s most significant technological advancements.
However, the first quarter of this year suggests that Ethereum can no longer address these issues in isolation. They are converging.
The network is emerging as a multi-directional force, with each path pulling it in varying, urgent directions, complicating the balancing act. Unlike previous cycles that were all about rapid shifts in narrative and price, the current challenges appear more foundational and structured.
These pressures are likely to persist, influencing Ethereum’s trajectory in the coming months.
For now, the emphasis remains on advancing the base layer, a process expected to gain momentum with the upcoming Gramsterdam upgrade this year. This upgrade will likely serve as a crucial test of the network’s capability to address issues that will successfully transition Ethereum into a strong, quantum-secure “layer of trust” able to support the global AI economy.
