Ethereum Foundation Launches PQ Hub and Quantum Security Plan

• Ethereum launches PQ hub to centralize research roadmap and multi-team coordination.
• Foundation targets 2029 upgrades with hard forks to address quantum security risks.
• Over 10 teams deploy PQ devnets as funding and research efforts expand.

The Ethereum Foundation has introduced a platform to coordinate its long-running effort to prepare the network for the risks posed by quantum computing. The initiative centers on a newly launched resource hub, pq.ethereum.org, which consolidates research, development progress, and technical planning tied to post-quantum (PQ) security. The release follows renewed internal prioritization of quantum resistance and outlines a structured roadmap to safeguard Ethereum’s infrastructure over the coming years.

Joint Push Toward Post-Quantum Readiness

The new platform brings together work from multiple teams, including post-quantum cryptography, protocol architecture, and protocol coordination units. According to the foundation, the effort builds on research that began in 2018, initially focused on STARK-based signature aggregation. Over time, this work has expanded into a broader, multi-team initiative spanning all layers of the protocol.

The website explains how quantum computing could affect various components of Ethereum and provides access to technical materials, including repositories, specifications, research papers, and Ethereum Improvement Proposals. It also includes a 14-question FAQ, a six-part interview series, and a roadmap hosted on strawmap.org outlining the transition path toward quantum-resistant infrastructure.

The Ethereum Foundation’s quantum team indicates that initial upgrades to mitigate quantum-related risks could be completed by 2029. These upgrades are expected to include multiple hard forks designed to strengthen cryptographic security across the network.

The foundation stated that quantum computing could break current public-key cryptography systems used for ownership, authentication, and consensus. While it noted that such capabilities are not expected in the immediate term, it emphasized that preparation requires multi-year development and testing.

As of March, more than ten client teams are already participating in the PQ Interop process, building and deploying development networks weekly. Projects including Lighthouse and Grandine have implemented PQ-focused devnets, with Prysm expected to follow.

Public Tracking and Research Commitments

Alongside the resource hub, the Ethereum Foundation has introduced a public dashboard to track progress toward quantum resistance across protocol layers. The dashboard follows a January statement by researcher Justin Drake, who identified post-quantum security as a top strategic priority for the organization.

Development activity is supported by ongoing research coordination, including biweekly sessions led by researcher Antonio Sanso focusing on post-quantum transactions. The foundation has also allocated funding to accelerate research, including a $1 million Poseidon Prize tied to improvements in hash functions and a separate $1 million Proximity Prize for broader post-quantum cryptography work.
