The Ethereum Foundation has made post-quantum security a central focus of the network’s long-term roadmap, announcing the formation of a dedicated Post Quantum (PQ) team.
The new team will be led by Thomas Coratger, a cryptographic engineer at the Ethereum Foundation, with support from Emile, a cryptographer closely associated with leanVM, according to crypto researcher Justin Drake.
“After years of quiet R&D, EF management has officially declared PQ security a top strategic priority,” Drake said in a Saturday post on X. “It’s now 2026, timelines are accelerating. Time to go full PQ.”
The researcher described leanVM, a specialized, minimalist zero-knowledge proof virtual machine (zkVM), as a core building block of Ethereum (ETH)’s post-quantum strategy.

EF backs post-quantum push with developer sessions, funding
Drake outlined several near-term steps aimed at preparing the ecosystem. A biweekly developer session focused on post-quantum transactions is set to begin next month, led by Ethereum researcher Antonio Sanso. The sessions will concentrate on user-facing protections, including protocol-level cryptographic tools, account abstraction pathways and longer-term work on aggregating transaction signatures using leanVM.
The Ethereum Foundation is also backing its push with new funding. Drake announced a $1 million Poseidon Prize to strengthen the Poseidon hash function, alongside another $1 million initiative known as the Proximity Prize, both aimed at advancing post-quantum cryptography.
On the engineering front, Drake said multi-client post-quantum consensus development networks are already live, with multiple teams participating and coordinating through weekly interoperability calls.
Furthermore, the foundation will host a dedicated post-quantum event in October, followed by a post-quantum day in late March ahead of EthCC. Educational efforts, including video content and materials aimed at enterprises, are also underway.

Coinbase forms board to assess quantum risks
The announcement comes amid growing sensitivity in crypto markets to quantum risk. On Wednesday, Coinbase revealed that it has established an independent advisory board to evaluate how advances in quantum computing could impact the cryptography securing major blockchain networks, including Bitcoin (BTC) and Ethereum.
The board brings together experts from academia and industry in quantum computing, cryptography, and blockchain security, and will publish public research and guidance for developers, organizations, and users. Its first position paper is expected in early 2027.
