The Ethereum Foundation has introduced a new platform, pq.ethereum.org, bringing all its post-quantum (PQ) research into one place. This marks a major step in preparing Ethereum for future risks from quantum computing.

8+ Years of Research Comes Together

This effort didn’t start recently. It goes back to 2018, when early research began on new cryptographic methods. Over time, multiple teams worked together to build a long-term plan for securing Ethereum.

The Foundation says the goal is not just to replace old systems, but to make the network stronger, simpler, and more decentralized for the long run.

What the New Platform Shows

The website explains how quantum technology could impact different parts of Ethereum, including execution, consensus, and data layers. It also shares a clear roadmap for how the network can slowly move to quantum-resistant systems.

Current estimates suggest that major Layer 1 upgrades could be ready by 2029, while full changes may take more time due to the scale of the network.

Moreover, Post-quantum security is part of Ethereum’s bigger plan, called the “strawmap.” This includes goals like faster transactions, better scaling, and improved privacy.

Notably, the roadmap outlines several upgrades expected over the next few years, with regular improvements planned. However, faster research progress could shorten these timelines.

Open Resources and Growing Participation

The platform includes open tools like research papers, technical specs, and FAQs to help developers understand the changes. It also features interviews in collaboration with Zero Knowledge FM.

More than 10 teams are already testing solutions, showing growing interest in post-quantum upgrades. The Foundation is also planning a research event in Cambridge in October 2026 to bring more experts together.

With this launch, the Ethereum Foundation is making its long-term security plans more open and easier to follow. It shows that Ethereum is preparing early for future challenges while continuing to improve its overall network.
