Reports say the Ethereum Foundation has started a new team to prepare the network for possible quantum computer attacks. These machines could one day break the math behind wallets and signatures. The team’s work is moving from research into practical tests and experiments, which has drawn attention across the crypto community.

Based on reports, Thomas Coratger will lead the effort. The team includes cryptographers and engineers already testing new systems on devnets. Some work ties into a project called leanVM and a researcher named Emile, who focuses on building simple quantum-safe tools. The goal is to test new algorithms in real software while keeping current transactions running smoothly.

Today marks an inflection in the Ethereum Foundation’s long-term quantum strategy.

We’ve formed a new Post Quantum (PQ) team, led by the brilliant Thomas Coratger (@tcoratger). Joining him is Emile, one of the world-class talents behind leanVM. leanVM is the cryptographic…

A $1 million prize has been set for improvements to the Poseidon hash function. Another $1 million prize supports broader post-quantum research. In total, roughly $2 million are being offered to labs and independent developers to design and test quantum-resistant solutions. Reports say this funding is meant to speed up work and show what can realistically replace current signatures.

Multi-client devnets are already active. Developers are experimenting with new signature types to see what works and what fails. Biweekly sessions led by researchers like Antonio Sanso let teams share results and update code. A Post-Quantum Day is scheduled for March 2026 before ETHCC, with a larger event planned in October 2026 to show progress and plan next steps.

Quantum computers could, in theory, break the ECDSA and secp256k1 schemes used today. That risk is not immediate but serious enough that Ethereum is acting now. Reports note users should watch for official guidance, follow wallet updates, and avoid reusing addresses once upgrades roll out.

Community reaction has been mixed. Some online discussions praised the careful planning, while traders noticed a small dip in ETH price. Others questioned how upgrades would reach millions of wallets and what happens to old keys. The Foundation’s approach is to test solutions early so users and services are better protected when changes happen.

This step is part of Ethereum’s long-term plan for safety. Tests will continue, standards will be debated, and progress will be shared publicly. By acting now, Ethereum aims to reduce risk and make future transitions smoother for everyday users and the network as a whole.
