The Ethereum ecosystem faces structural pressures in 2026 regarding scalability, quantum security, and AI strategy. Co-founder Vitalik Buterin has criticized the centralization of existing layer-2 networks, predicting consolidation trends. Meanwhile, the foundation has incorporated quantum security into its roadmap and positioned Ethereum as a trust layer for decentralized AI systems.

Deep Tide TechFlow News, March 23: According to CoinDesk, the Ethereum ecosystem is facing structural pressures from three dimensions—scalability roadmap, quantum security threats, and AI strategic positioning—by early 2026, marking a critical point for reassessing its direction.

In terms of scalability, Ethereum co-founder Vitalik Buterin criticized existing Layer 2 networks (L2), pointing out that some Rollup solutions rely on centralized components, cause severe ecosystem fragmentation, and fail to truly inherit the security and decentralization features of the main chain. They are not effective Ethereum scaling solutions. Analytical firm 21Shares predicts that the L2 space will undergo consolidation, with the market focusing on networks highly aligned with Ethereum and offering stronger performance.

Regarding quantum security, the Ethereum Foundation has included post-quantum signature schemes and LeanVM research in its recent plans. Buterin also released a related roadmap, officially prioritizing quantum threats as a mid-term issue.

In the AI domain, the Foundation positions Ethereum as the “trust layer” for decentralized AI systems, exploring infrastructure roles for verifiable outputs and economic activities between machines.
