The Ethereum Foundation has officially established a dedicated team focusing on post-quantum security, responding to growing concerns about the implications of quantum computing for blockchain technology. This initiative, set to roll out in 2026, includes a significant financial commitment of $2 million aimed at advancing cryptographic research and development.
Leading the new Post-Quantum (PQ) team is cryptographic engineer Thomas Coratger, with support from key contributors associated with leanVM. This framework is crucial for Ethereum”s strategy, designed to facilitate hash-based cryptography and zero-knowledge systems that will remain secure even if existing elliptic curve signatures are compromised.
Historically, work on quantum resistance within Ethereum has been underway since 2019. However, the urgency has escalated, particularly in 2024, when post-quantum security became a foundational element of the leanEthereum roadmap. As of 2026, Ethereum is intensifying its efforts to develop solutions that are ready for production, shifting from theoretical frameworks to practical implementation.
A key aspect of this initiative is the movement towards live development networks. Multi-client PQ consensus devnets are currently operational, engaging both new and established client teams, such as Lighthouse and Grandine, with Prysm expected to join shortly. This collaborative approach demonstrates Ethereum”s commitment to enhancing its protocol-level security.
Moreover, Antonio Sanso will facilitate biweekly All Core Devs breakout sessions focused specifically on PQ transactions. These discussions aim to address user-facing security upgrades, including protocol precompiles and transaction signature aggregation techniques utilizing leanVM. The objective is to ensure a seamless transition that does not compromise wallet security or disrupt the network.
In addition to its research and development efforts, the Ethereum Foundation is also amplifying educational initiatives. A three-day post-quantum conference is planned for October, building on the previous event held in Cambridge. Furthermore, a one-day seminar will take place in Cannes prior to the EthCC conference in March.
As part of its financial backing for research, Ethereum is implementing two $1 million initiatives aimed at advancing hash-based cryptographic methods. Recently, advancements in mathematical AI have allowed for significant reductions in the time required for cryptographic proofs, highlighting the rapid pace of development in this crucial field.
Overall, Ethereum”s strategic pivot towards post-quantum security not only aims to fortify its cryptographic foundations but also positions the network to effectively respond to the evolving landscape of quantum computing threats.
