The Ethereum Foundation has reportedly launched a new team to prepare its network for potential quantum computer attacks. These machines could someday break the wallets and the calculations behind the signatures. The team’s work has moved from research to practical testing and experimentation, gaining attention across the crypto community.
Ethereum launches post-quantum team
According to reports, Thomas Kolatgar will lead the effort. The team includes cryptographers and engineers who are already testing the new system on devnet. Some of the research is related to a project called leanVM and a researcher named Emile who is focused on building simple quantum-safe tools. The goal is to test new algorithms in real software while keeping current transactions running smoothly.
Today marks a turning point in the Ethereum Foundation’s long-term quantum strategy.
We’ve assembled 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 encrypts…

$2 million prize boosts development
A $1 million prize has been set for improving Poseidon’s hash function. An additional $1 million award will support a wide range of post-quantum research. In total, approximately $2 million will be provided to laboratories and independent developers to design and test quantum-resistant solutions. The funding is reportedly aimed at accelerating work and demonstrating what could realistically replace the current signature.
Early testing and community engagement
Multi-client devnet is already active. Developers are experimenting with new signature types to see what works and what fails. Biweekly sessions led by researchers like Antonio Sanso allow the team to share results and update the code. A post-quantum day is planned for March 2026 before ETHCC, and a large event is planned for October 2026 to show progress and plan next steps.
In theory, quantum computers could break through the currently used ECDSA and secp256k1 schemes. The risk is not immediate, but it is serious enough that Ethereum is acting now. The report notes that users should check official guidance, follow wallet updates, and avoid reusing addresses once the upgrade begins.
Community reaction has been mixed. While some online discussions praised the careful planning, traders noted a slight decline in ETH prices. Some questioned how the upgrade would reach millions of wallets and what would happen to old keys. The Foundation’s approach is to test solutions early to better protect users and services when changes occur.
This step is part of a long-term plan for Ethereum security. Testing will continue, standards will be discussed, 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.
