Analysis: Ethereum faces a critical moment in a high-risk balancing strategy

According to CoinDesk analysis, as the pressure from expansion problems, quantum technology and artificial intelligence increases day by day, Ethereum is facing a critical moment in its high-risk balancing strategy. In the first three months of 2026, the Ethereum ecosystem faced multiple structural pressures. VitalikButerin sharply criticized the Layer2 expansion path at the beginning of the year, pointing out that many Rollup designs relied on centralized components and isolated environments and failed to truly inherit the security guarantees of the main network, resulting in inconsistent ecological fragmentation and security assumptions.<br /> At the same time, the Ethereum Foundation has included anti-quantum computing threats in its recent plans, promoting research such as LeanVM and post-quantum signature schemes. At the internal level, TomaszStańczak, co-executive director of the Ethereum Foundation, resigned after about a year in office, a change seen as a signal of a re-alignment of priorities within the foundation. In addition, the foundation is accelerating the deployment of decentralized AI research, trying to position Ethereum as a "trust layer" for AI systems to verify output, coordinate agents, and support machine-to-machine economic activities.<br /> Overall, Ethereum can no longer deal with these issues in isolation; they are intertwined. The network is being pulled in multiple directions at the same time, making it increasingly difficult to maintain balance. Unlike previous cycles, the current dilemma is more about structure than short-term momentum. In the short term, the focus will still be on the expansion of the main network. The planned upgrade of Glamestead will become a touchstone to test whether the Ethereum network can be successfully transformed into a stable, quantum-resistant "trust layer" that supports the global AI economy.
