The Ethereum Foundation has officially elevated post-quantum cryptographic security to a central strategic priority by announcing the creation of a dedicated 'Post Quantum' team and a series of initiatives aimed at strengthening the network against future threats related to quantum computing.
In a post on X, Ethereum Foundation researcher Justin Drake indicated that the new team will be led by Thomas Coratger, with the support of cryptography contributor Emile, known for his work on leanVM.
This announcement marks a transition from several years of discreet research to an active engineering phase, including coordination across the entire core Ethereum engineering community.
From research to execution at network scale
The foundation plans bi-weekly 'All Core Devs' calls focused on post-quantum transactions, including work on dedicated precompiles, account abstraction, and transaction signature aggregation via leanVM.
Multi-client post-quantum consensus test networks are already operational, involving teams such as Lighthouse, Grandine, Zeam, and Prysm, coordinated through weekly interoperability sessions.

Funding, devnets, and cryptographic bets
To stimulate research, the Foundation has announced two $1 million reward programs each: a new 'Poseidon Prize' aimed at enhancing the Poseidon hash function, and the existing 'Proximity Prize,' which supports broader work in post-quantum cryptography.
These incentives reflect a strategic investment in cryptographic foundations based on hash functions, which Ethereum believes will provide strong and efficient security against quantum capabilities.
The Foundation has also outlined its plans for future events, including a three-day post-quantum workshop in October and a day dedicated to PQ before EthCC, aimed at bringing together experts and developers around the implementation of post-quantum solutions.
A comprehensive roadmap will be published on the future site pq.ethereum.org, with the goal of a lossless transition of funds and uninterrupted network operation.
Why it matters
This initiative comes in the context of increasing sector attention to the potential capability of quantum computing to disrupt cryptographic systems.
Even though quantum computers capable of breaking current encryption do not yet exist, experts have long warned about the need for post-quantum cryptography to protect blockchains relying on public key algorithms currently in use.
The acceleration of Ethereum's approach highlights a proactive long-term security strategy that links research and practical development, positioning the network to adapt before advancements in quantum computing threaten existing cryptographic assumptions.
