- Ethereum Foundation has formed a dedicated Post-Quantum team to address accelerating quantum threats.
- The effort is led by Thomas Coratger and contributors behind LeanVM, labeled a core element of the strategy.
- New developer measures include biweekly All Core Developers calls on post-quantum transactions starting in February.
- The program includes live post-quantum devnets and prize funding totaling $2 million, including a $1 million Poseidon Prize.
- Leadership aims for a full post-quantum roadmap that prevents fund loss and avoids network downtime.
The Ethereum Foundation has elevated post-quantum security and created an internal Post-Quantum (PQ) team, a move announced on January 23, 2026 in a post by Justin Drake on X. The initiative aims to harden the protocol against future quantum computing threats and to keep the network secure without frequent emergency upgrades.
The new team will be led by Thomas Coratger, with key contributors from LeanVM, which Drake described as "the cryptographic cornerstone of our entire post-quantum strategy." Coratger’s profile is available on Twitter. Drake said the work on PQ began in 2019 and that timelines have recently accelerated.
Drake used the announcement to stress a strategic shift: "After years of quiet R&D, EF management has officially declared PQ security a top strategic priority," and "It’s now 2026, timelines are accelerating. Time to go full PQ." The team plans a full post-quantum roadmap with the stated goal of zero fund loss and no network downtime.
Starting in February, researcher Antonio Sanso will lead biweekly All Core Developers breakout calls on post-quantum transactions. Those calls will focus on user-facing issues such as account abstraction and transaction signature aggregation.
The program will support live post-quantum devnets and incentive prizes. Drake announced a total of $2 million in prizes and a $1 million Poseidon Prize to strengthen the Poseidon hash function. Drake also noted his participation on a quantum advisory board at exchange Coinbase, aligning with broader industry efforts. He concluded the announcement urging belief in the effort: "Believe in something. Believe in [post-quantum] security."
