Is the Ethereum Foundation prioritizing post-quantum crypto?
2026-01-25 • Ian Irizarry
TL;DR
The Ethereum Foundation has prioritized post-quantum cryptography (PQC) by forming a dedicated team to safeguard the network against future quantum computing threats. This proactive approach not only secures Ethereum's infrastructure but also presents new funding opportunities for companies developing quantum-resistant technologies.
Ethereum Takes a Big Step Toward Quantum-Resistant Security
Here's the thing: back in January 2026, the Ethereum Foundation (EF) stepped up big time. They launched a specialized Post-Quantum (PQ) team, shifting gears from just research to actually building quantum-proof cryptography. Thomas Coratger, a cryptographic engineer, is leading the charge with help from Emile, who’s well-known for contributions to leanVM. This clearly shows how serious Ethereum is about safeguarding its future. Ethereum Foundation Post-Quantum Security Team
Justin Drake, senior researcher at EF, didn’t mince words:
"After years of quiet R&D, EF management has officially declared PQ security a top strategic priority." Ethereum Foundation Post-Quantum Security Team
Why Quantum Computing Is Such a Headache for Blockchain Security
Quantum computers could basically dismantle the cryptographic algorithms we rely on today, especially those based on elliptic curve cryptography (ECC). Shor’s algorithm, for example, can solve problems that would take classical computers forever. So, the encryption methods protecting wallets and transactions risk becoming obsolete sooner than you think. I’ve found that many enterprises aren’t ready for this shift—almost half admit they haven’t prepared for quantum cybersecurity threats yet.

Ethereum’s Key Post-Quantum Projects
The PQ team at Ethereum is juggling a few critical initiatives right now:
Engineering and Security Improvements: Moving beyond theory, they’re actively upgrading wallet security and protocol cryptography. Ethereum Foundation Makes Post-Quantum Security Top Network Priority
Developer Sessions: Every two weeks, Antonio Sanso leads discussions covering post-quantum transactions, account abstraction, and new crypto methods.
LeanVM Integration: LeanVM, a streamlined zero-knowledge proof virtual machine, gets center stage here. It’s optimized for quantum-resistant hash-based signatures and plays a big role in Ethereum’s PQ strategy. LeanVM Integration
Just a quick aside: while these sessions are super informative, joining them regularly might require a decent time commitment, which some smaller teams could struggle with.
Big Bucks and Grants for Quantum-Resistant Tech
Ethereum’s putting their money where their mouth is—literally. They’ve set aside serious funding, including two $1 million prizes:
Poseidon Prize: Targets toughening the Poseidon hash function.
Proximity Prize: Broader, focusing on advancing PQ tech overall. Poseidon & Proximity Prizes
These prizes create a fantastic chance for companies building quantum-resistant solutions to secure funding and collaborate with Ethereum’s PQ team.
How to Get Involved with Ethereum’s PQ Efforts
Wondering how to jump in? Here’s a quick checklist:
Stay Updated: Keep an eye on Ethereum Foundation announcements and jump into those developer sessions.
Collaborate: Reach out to the PQ team. Syncing your R&D efforts with their roadmap is key.
Apply for Grants: Don’t miss out on those prize submissions. They’re a great way to fund innovative projects.
What This Means for the Blockchain World
Ethereum’s proactive approach is setting the bar high. By tackling quantum threats head-on, they’re not just protecting their own network; they’re pushing the entire blockchain ecosystem to get serious about future risks. This focus on PQC is also fueling innovation. Companies that get involved now have a chance to gain a competitive advantage in what’s shaping up to be a crucial part of crypto’s next chapter. Long story short, Ethereum is making sure its platform stays reliable and trusted for years to come. And if you’re in the business of quantum-resistant tech, now’s the moment to make your move.
