The first couple of months of 2026 have forced the Ethereum community into a kind of introspection—one that goes beyond price, beyond technical upgrades, and into the question of what the network is actually trying to be.
Even before this year, there has been a sense among builders and executives that Ethereum was on the verge of another growth phase—this time driven not by crypto-native users but by institutions and technology. Neobanks, as some argued, would quietly onboard millions by abstracting away the complexity of wallets and gas fees. Ethereum, in this framing, wouldn’t need to win users directly. It would sit beneath the interface, powering a new financial stack that, on the surface, looked nothing like crypto.
It was a continuation of a long-running thesis: that Ethereum’s success would come from invisibility.
That vision has been shaped in part by years of previous upgrades aimed at improving user experience and reducing costs. Changes like “proto-danksharding”, introduced in the Dencun upgrade, significantly lowered fees for layer 2 networks by increasing data downloads for transactions, while ongoing improvements to the base layer have made transactions more efficient.
While the price of the network's ether (ETH) token has been determined by market forces, these upgrades have, together, helped move Ethereum closer to a model where users interact with applications without needing to understand the underlying infrastructure.
But that narrative began to change a few weeks into the year, refocusing on the core roadmap.
The L2 debate
Earlier this year, the co-founder of the network, Vitalik Buterin, delivered a sharp reality check to the broader ecosystem: “You are not scaling Ethereum.”
The comment cut through what had, until then, been a largely celebratory conversation around rollups. These types of networks, also known as layer-2 (L2) networks, process transactions off Ethereum and then bundle them back onto the main chain to make it faster and cheaper. Layer-2 networks have exploded over the last few years, transaction fees have come down, and activity has spread—but the deeper question was whether any of this amounted to coherent scaling.
Buterin’s argument went further than a general critique of progress. In his view, many of today’s layer 2 designs are drifting away from Ethereum’s core model: relying on centralized components and siloed environments that don’t fully inherit the guarantees of the base chain. The concern wasn’t that L2s exist, but that in their current form, they may not be delivering the kind of scaling Ethereum was meant to achieve.
His critique highlighted a growing unease.
Fragmentation across L2s, inconsistent security assumptions, and reliance on centralized components were beginning to look less like temporary trade-offs and more like structural risks. Ethereum, in trying to scale outward, risked losing the very properties that made it valuable in the first place—its strong security, decentralization, and role as a shared, neutral settlement layer where applications and liquidity can seamlessly interoperate.
L2 teams, for their part, didn’t push back so much as recalibrate. Some acknowledged the critique and leaned into a future where rollups differentiate through specialization: privacy, consumer apps, or unique execution environments, rather than simply acting as cheaper Ethereum. Others defended their role more forcefully, arguing that high-throughput environments are still essential.
Ethereum’s base layer, meanwhile, has made incremental progress on its own. Recent upgrades, such as December’s Fusaka hard fork, increased data capacity and efficiency on the main network, allowing more transactions to be processed while lowering costs. Although that spike in transactions came under scrutiny recently, with some calling them 'address poisoning' scams.

This could also lead to consolidation among the layer 2 networks, according to 21shares. "The year ahead is likely to mark Ethereum’s L2 consolidation: a leaner, more resilient layer anchored by ETH-aligned, exchange-backed, and high-performance networks," the firm said in a research report.
The quantum threat
At the same time, another issue—long discussed but rarely urgent—suddenly moved up the priority list: Quantum Computing.
The Ethereum Foundation signaled a shift in posture, elevating efforts like 'LeanVM' and post-quantum signature schemes. What had once been treated as a distant, almost academic concern was now being folded into near-term planning.
The implication was hard to ignore: the network is no longer just building for the next cycle, but for threats that could fundamentally break its cryptographic assumptions. The foundation has signaled it is taking that risk seriously, establishing dedicated research efforts focused specifically on post-quantum security.

The internal shuffle
If scaling exposed cracks in Ethereum’s present, quantum risk cast a shadow over its future, and it seemed that the network was taking the threat seriously.
Then came changes from within.
The departure of Tomasz Stańczak as co-executive director of the Ethereum Foundation marked more than a leadership reshuffle. At a moment when the network is facing technical, strategic, and philosophical reevaluations all at once, even subtle shifts at the top can signal a broader recalibration.
The move also came as something of a surprise.
The foundation is not known for abrupt shifts, and Stańczak had only stepped into the role about a year earlier, following the long-standing tenure of Aya Miyaguchi. In an ecosystem that tends to favor continuity, the rapid turnover hinted at a deeper internal recalibration underway, as the foundation reassesses its priorities amid growing demands for scaling, security, and Ethereum’s potential role in new frontiers such as artificial intelligence (AI).
'Trust layer'
And AI, a topic that has become impossible to ignore, not just for crypto but for every industry, began to shape a separate line of thinking for the network.
Buterin outlined how Ethereum could play a foundational role in the future of artificial intelligence. The vision extends beyond payments or DeFi—into a world where Ethereum acts as a coordination layer for decentralized AI systems, enabling verifiable outputs, trust-minimized data sharing, and machine-to-machine economic activity.
That push didn’t emerge overnight.
Early last year, the foundation spun up a dedicated decentralized AI research unit (dAI) exploring how the network could support autonomous agents and machine-to-machine economies. What felt experimental at the time has since accelerated into something more deliberate in 2026, with the foundation increasingly framing Ethereum as a potential “trust layer” for AI: a system for verifying outputs, coordinating agents, and anchoring a rapidly evolving ecosystem that, until now, has been largely controlled by centralized players.
All of this is an ambitious expansion of scope, placing Ethereum at the intersection of two of the most consequential technologies today.
But overall, the first three months of the year suggest that Ethereum no longer has the luxury of tackling these questions in isolation; rather, they are converging.
What emerges is a network being pulled in multiple directions, each one with its own sense of urgency, and a balancing act is becoming harder to ignore. And unlike previous cycles, where narratives could shift as quickly as prices, the issues now feel deeper, less about momentum, and more about structure.
These tensions are unlikely to be resolved anytime soon and will continue to shape Ethereum’s trajectory in the months ahead.
In the immediate term, however, the focus remains on scaling the base layer, with the upcoming Glamsterdam upgrade, slated for this year, expected to accelerate that effort. The upgrade will likely become a litmus test for the network's ability to solve issues that can successfully shift Ethereum into a robust, quantum-secure "trust layer" capable of anchoring the global AI economy.
