While enabling experimentation and significant performance gains, it's still too expensive for Ethereum PQ scaling. That's why we propose adding NTT as a precompile—paving the way for PQ crypto-agility rather than locking into a single candidate. 👉: github.com/ethereum/EIPs/…

ZKNox is proud to be delivering the fastest FALCON PQ signature contract as part of EF experimentations github.com/ZKNoxHQ/ETHFAL…

smol(er) update : since the last post we managed to cut further the gas cost from 3.6M to 1.9M by intensively yul-ing critical sections of the FALCON verification

1/ Introducing ZKnox zknox ! This new research organization is at the forefront of advanced cryptography, backed by a grant from the Ethereum Foundation. Their mission: provide high impact open source code that improves Ethereum security and efficiency.

After FALCON, our team developped an EVM version of DILITHIUM. While gas cost is higher, it has a simpler structure for HW signer implementation (incoming). Soon a blog post to sum-up pro and cons for both schemes. github.com/ZKNoxHQ/ETHDIL…

New blog post : implementation of post-quantum signature schemes FALCON and DILITHIUM on Ethereum zknox.eth.limo/posts/2025/03/…

Exploiting a bug in Keystone 3 Pro Keystone Hardware Wallet old firmware to run your own code github.com/zknoxhq/ks3-de… - make sure to update to the latest version keyst.one/firmware - this was disclosed responsibly as part of our efforts to improve the ecosystem

Huge thanks to zknox for a responsible disclosure. This vulnerability was already fixed in firmware V1.2.6, thanks to our collaboration with our security partners SlowMist, Offside Labs & BlockSec. By the time we received the report, firmware 1.6.0 had already

Joint work with Linea and Alpen Labs to reduce ECC proving time. This is the opportunity to update protocols to bls12-381 without extra proving cost. eprint.iacr.org/2025/933

Tomorrow at ETHPrague we'll present PQ migration scenarios and our smart contracts implementation results

ZKNOX twice on stage in Cannes from June 30th to July 7th for EthCC - Ethereum Community Conference [8], the week's events, and then hacking at ETHGlobal Hackathon. I will present our Pq smart contracts, plus our insights for a pq Ethereum Era.

Bullish on private payments powered by CairoM/Stwo! 🔥🔥 Super insightful talk by Reno ⚫️⚪️ zknox on the path to PQ cryptography in Ethereum. STARKs will help to aggregate large PQ signatures, and could also become an efficient hash-based stateful signature scheme

Our CEO Nicolas Bacca  presented yesterday what are the challenges to migrate hardware wallets after having PRed 3 of them to integrate Account Abstraction  EIP-7702.

ETHCC was a blast, our team then attended ethglobal to hack this week end and obtained the second prize from the Ethereum Foundation ethglobal.com/showcase/zkipp…. ZKipper introduces post quantum RBAC (role based access), and use our PQC library along client side proving with gnark library.
