Ethereum doubles down on post-quantum security
The Ethereum Foundation has elevated post-quantum resilience to a core strategic priority, announcing a dedicated Post Quantum (PQ) team and new funding initiatives to strengthen protocol cryptography. This move signals an accelerated drive to make Ethereum quantum-resistant across wallets, transactions, and consensus layers.
New leadership, research and developer engagement
The PQ team will be led by Thomas Coratger, a cryptographic engineer at the Ethereum Foundation, backed by notable cryptographers including Emile, a contributor tied to the leanVM project, as highlighted by researcher Justin Drake. After years of discreet research and development, foundation leadership has formally prioritized PQ security and is mobilizing resources and timelines to move from R&D into engineering and deployment.
Biweekly developer sessions
Beginning next month, a biweekly developer workshop series will focus on quantum-resistant transactions. Led by Ethereum researcher Antonio Sanso, these sessions will center on pragmatic, user-facing defenses: protocol-level cryptographic tools, account abstraction pathways, and longer-term work on aggregating transaction signatures with leanVM and minimalist zkVM approaches. The goal is to produce developer-ready patterns that improve transaction privacy and quantum resistance while preserving usability.
Funding to harden cryptographic primitives
To catalyze cryptographic advances, the Foundation has committed $2 million across two prize programs. A $1 million Poseidon Prize will invest in hardening the Poseidon hash function—a key primitive for zero-knowledge and blockchain proofs—while a separate $1 million Proximity Prize focuses on advancing post-quantum cryptography research relevant to Ethereum.
Engineering progress and events
On the engineering front, multi-client post-quantum consensus development networks are already active, with diverse teams coordinating via weekly interoperability calls. The Foundation plans to host a dedicated post-quantum event in October and a post-quantum day in late March ahead of EthCC, alongside educational content and enterprise-focused materials to help builders and organizations prepare.
Industry-wide concern over quantum risk
Interest in quantum resilience is rising across the crypto sector. Coinbase recently announced an independent advisory board to assess the impact of quantum computing on blockchain cryptography for networks such as Bitcoin and Ethereum. The board will publish public research and guidance for developers and organizations, with an initial position paper expected in early 2027.
What this means for users and developers
For developers, the Foundation’s roadmap provides clearer coordination, funding, and interoperability testing for quantum-safe cryptographic transitions. For users and enterprises, the emphasis on account abstraction, signature aggregation, and hardened hashing aims to make future migrations more seamless and secure. While full post-quantum deployment remains a multi-year effort, these steps accelerate engineering milestones and community readiness.
As quantum computing capabilities advance, the move toward quantum-resistant cryptography will become essential to maintaining blockchain security. Ethereum’s combined strategy of focused teams, developer education, interoperability testing, and financial incentives is designed to keep the network resilient as the quantum era approaches.

Poseidon focus ok but is that enough? Who handles key rotation for billions of wallets, and what's the fallback if quantum speeds up? feels optimistic, maybe naive

Whoa, PQ team and $2M prizes? Finally some teeth behind the talk. Hope they move fast, but timelines always slip... curious about migration UX
