Ethereum Foundation Makes Post Quantum Security Top Network Priority

TLDR

• Ethereum Foundation launches dedicated team for post quantum blockchain security.
• Two $1M prizes will support cryptographic research and protocol upgrades.
• Developer sessions and devnets to focus on post quantum transaction safety.
• Community education events planned ahead of EthCC in March 2026.

The Ethereum Foundation (EF) is increasing its efforts on post quantum security by forming a dedicated team to address future risks. This move is described as a top strategic priority due to concerns about the timeline of quantum computing breakthroughs.

EF researcher Justin Drake confirmed the new Post Quantum (PQ) team will be led by Thomas Coratger. He will work alongside Emile, a cryptographer behind leanVM, a key component of the project’s new technical approach.

New Team to Focus on Engineering and Safety Upgrades

The PQ team will shift Ethereum’s post quantum work from background research into active development. Drake said the initiative aims to secure wallet systems and protocol-level cryptography.

The group will hold biweekly developer sessions to address post quantum transactions. These sessions will begin next month and will be led by Antonio Sanso. Topics include account abstraction and new cryptographic methods inside Ethereum’s protocol.

The effort also includes leanVM, a tool for safe cryptographic computation. Drake said leanVM will be used for future signature aggregation and transaction verification.

Research Funding and Development Networks Underway

To support new cryptographic tools, EF will offer two $1 million prizes. The Poseidon Prize will focus on hardening the Poseidon hash function. The Proximity Prize will support broader post quantum cryptographic research.

Drake confirmed that post quantum test networks are already running with multiple clients. Weekly calls are held to coordinate between engineering teams. These test networks are key to developing a safe transition plan before quantum threats arise.

Community concerns have grown due to headlines about the risks of quantum computing. Although real-world threats are not immediate, EF aims to prepare early by testing tools and systems well in advance.

Community Events and Education Planned

The Ethereum Foundation is planning several events to increase awareness and understanding of post quantum risks. A post quantum event is scheduled for October, and a dedicated Post Quantum Day is planned in March, before EthCC.

Education materials will also be released. EF plans to launch a video series and distribute resources focused on enterprises and developers. These efforts aim to help users and organizations adapt to upcoming changes.

Drake emphasized the importance of early preparation. “Blockchains can coordinate a full software transition faster than traditional finance,” he said.

Long-Term Focus Despite Delayed Threat Timeline

Quantum computers are still under development, but experts say they could one day break current encryption methods. This includes cryptographic algorithms used to protect Ethereum wallet keys.

The challenge for Ethereum and other networks is not only in building post quantum systems. It also includes safely updating wallets, migrating users, and maintaining normal use during changes.

Pantera Capital’s Franklin Bi noted that traditional finance might need years to upgrade, but blockchain platforms like Ethereum are better positioned for quicker transitions.

EF’s strategy centers on readiness, long-term safety, and maintaining user trust across its ecosystem. The new team and funding are part of that broader preparation.
