Ethereum Foundation Forms Group for Post-Quantum Security
The Ethereum Foundation has announced the formation of an independent Post Quantum (PQ) Group, making post-quantum security a central focus of the network's long-term roadmap.
The new team is led by Thomas Koratger, a cryptographic engineer at the Ethereum Foundation, with support from Emile, a cryptographer closely associated with leanVM, said crypto researcher Justin Drake.
“After years of R&D silence, EF management has officially declared that PQ safety is a top strategic priority.” “It's 2026, timelines are speeding up. It's time to go full PQ,” Drake said in a post on X Saturday.
The researcher described LinVM, a unique, minimal zero-knowledge verification virtual machine (zkVM) as the core building block of Ethereum's (ETH) post-quantum strategy.

EF supports the post-quantum push through developer sessions, funding
Drake outlined several recent steps they plan to take to prepare the ecosystem. A bi-weekly developer session focused on post-quantum transactions, led by Ethereum researcher Antonio Sanso, is set to begin next month. The sessions will focus on user-facing protections using protocol-level encryption tools, account abstraction traces, and long-term transaction signatures using leanVM.
The Ethereum Foundation is also backing the push with new funding. Drake announced a $1 million Poseidon Prize to bolster the Poseidon hash function, alongside an additional $1 million initiative that both aims to advance post-quantum cryptography.
On the engineering front, Drake said the multi-client post-quantum consensus development networks are already live, with multiple teams participating and coordinating through weekly functional communication calls.
In addition, the Foundation will host a limited post-Quantum event in October, followed by a post-Quantum Day in late March before Etsy. Educational efforts are also underway, including video content and materials aimed at enterprises.

Coinbase Forms Board to Review Quantum Risks
The announcement comes amid growing exposure to quantum risk in crypto markets. On Wednesday, Coinbase announced that it has formed an independent advisory board to assess how advances in quantum computing could affect the cryptographic authentication of 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 publishes public research and guidance for developers, organizations and users. The first position paper is expected in early 2027.
