TechFlow to a report by CoinDesk on March 23, the Ethereum ecosystem faces structural pressures from three dimensions—scaling roadmap, quantum security threats, and AI strategic positioning—in early 2026, and is at a critical juncture for reassessment.
Regarding scaling, Ethereum co-founder Vitalik Buterin criticized existing Layer 2 (L2) networks, pointing out that some rollup solutions rely on centralized components, suffer from severe ecosystem fragmentation, and fail to truly inherit the security and decentralized characteristics of the main chain, thus not representing effective Ethereum scaling. Analyst 21Shares predicts that the L2 space will consolidate, with the market concentrating on networks that are highly aligned with Ethereum and offer superior performance.
In terms of quantum security, the Ethereum Foundation has included post-quantum signature schemes and LeanVM in its recent plans, and Buterin has also released a related roadmap, officially listing quantum threats as a medium-term priority issue.
In the field of AI, the foundation positions Ethereum as the "trust layer" of decentralized AI systems, exploring its role as an infrastructure for verifiable outputs and inter-machine economic activities.
