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

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

RT @RenaudDUBOIS10: ZKNOX twice on stage in Cannes from June 30th to July 7th for @EthCC [8], the week's events, and then hacking at @ETHGl….

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

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.

New blog post : strategies for Hardware Wallet vendors to use EIP-7702 quickly and efficiently

@SimonMasson2 With Bandersnatch, switching to BLS for ZKDapps such as Railgun could be done with a lesser proving effort than BN. The note includes the spoiler of an incoming scientific article in collaboration with @YoussefElHousn3. Other generic curves circuit optimizations are described.

Privacy, ZKNOX has your back ! Here is the fastest in circuit ECC over Pectra incoming BLS scalar field with implication on RAILGUN like schemes. We are honored to count among us @SimonMasson2, a Bandersnatch designer. Check our latest post :

RT @KeystoneWallet: Huge thanks to @zknoxhq for a responsible disclosure. This vulnerability was already fixed in firmware V1.2.6, thanks….

Exploiting a bug in Keystone 3 Pro @KeystoneWallet old firmware to run your own code - make sure to update to the latest version - this was disclosed responsibly as part of our efforts to improve the ecosystem.

We deployed a contract to verify a NIST compliant FALCON on L1 and Optimism at 0x5dc45800383d30c2c4c8f7e948090b38b22025f9. While several parts of ETHEREUM are prone to Quantum computing, begin experimentations to secure accounts from now! Details:

New blog post : implementation of post-quantum signature schemes FALCON and DILITHIUM on Ethereum

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.

RT @ethereumfndn: 1/ Introducing ZKnox @zknoxhq ! This new research organization is at the forefront of advanced cryptography, backed by a….

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.

ZKNox is proud to be delivering the fastest FALCON PQ signature contract as part of EF experimentations

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. 👉:
