Ethereum Foundation Sets Quantum Security and Gas Limit Expansion as 2026 Priorities

The Ethereum Foundation has outlined an ambitious roadmap for 2026, placing network scalability and higher transaction capacity at the center of its protocol priorities. Among the key objectives is raising Ethereum’s gas limit beyond 100 million, significantly expanding the amount of computational work each block can process.

The gas limit, which was increased from 30 million to 60 million during 2025 following the Pectra and Fusaka upgrades, is expected to climb further as developers optimize performance. Some community members have suggested that reaching 180 million could serve as a baseline target rather than an upper bound.

Post-Quantum Security and Interoperability Focus

Beyond scaling, the foundation identified “post-quantum readiness” as a critical component of its long-term security strategy. A dedicated research team has been formed to prepare the network for potential advances in quantum computing that could threaten current cryptographic standards.

Improvements to user experience are also planned, including smarter wallet functionality through native account abstraction and enhanced cross chain interoperability. Meanwhile, Vitalik Buterin recently emphasized the importance of aligning blockchain innovation with artificial intelligence in ways that strengthen financial systems and preserve user autonomy.
