Prevent Bybit hack by separating roles with 7702: - modify the contract -> sudo cmd - standard signing -> user cmd +hide the governance using ZK signer. We used our ZKNOX PQC library for long term administration, and bind gnark with FFI for mopro.

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.

Hell yeah ! This is the direction of history.

Using hash-based signatures instead of lattices is like picking RSA instead of ECC: use what any good engineer can get quickly instead of the one requiring more number theory skills and pushed by IACR. We lost decades of ECC generalization because of this. Please not twice.

Privacy is a right, not a crime.

(1/11) Ethereum's future demands faster, smaller, and post-quantum secure SNARKs. A key challenge is proximity testing in modern proof systems. Enter WHIR: a new hash-based protocol designed for this task. Today we just published: "WHIR for Ethereum" 👇 ethresear.ch/t/whir-for-eth…

hot wallets are a (security) bug; cold hardware wallets are a (security) feature. It might be a controversial take (or maybe not lol) but the reality is most people simply can't securely manage a hot wallet. Computers are constantly being infostealer-compromised, people save pks

🚨 There’s a large-scale supply chain attack in progress: the NPM account of a reputable developer has been compromised. The affected packages have already been downloaded over 1 billion times, meaning the entire JavaScript ecosystem may be at risk. The malicious payload works

Using a hardware wallet without having a red team like donjon having audited it is like using an unaudited DefiApp. Gg, once again. Like it or not Ledger+multisigner remains the best choice.

Dont trust, verify, diversify.

Zoom out chart of any non RWA/stable token but $ETH and $BTC in the long run.

1/ It’s time for us to go public so you all can go private, and it’s time for us to be bold so you all can be safe. As part of our work with the Ethereum Foundation, vitalik.eth and I are proud to be the faces of Kohaku. 🧵👇

New milestone: Post-quantum e2e on-chain verification: Over 20k proofs sent since the integration of Falcon signatures. This rapid progress owes much to zknox's work (including Simon Masson, Reno ⚫️⚪️ & Nicolas Bacca) ETHFALCON, which inspired yh's Sui-Falcon.

Privacy is normal and deserves the best security - zknox will provide a portable ethereum application interoperable with different hardware vendors to run sensitive privacy operations in a secure enclave and clear sign them. Detailed architecture will be unveiled soon.

With Kohaku this is coming to an end. Time to change the broken app model and blow up the vendor locks ! We will do all the top DeFi protocol by TVL. It will take us a few months to cover 90% of ethereum's DeFi. Thanks to Nicolas Bacca zknox notes.ethereum.org/@niard/KohakuR…

Dope. The day it happens ETH immediately becomes a BTC L2. As well as all programmable chains are currently becoming L2s of ethereum. Luckily for ethereum, Bitcoin can't agree on very basic modifications. So a stark... Won't happen before lean eth. as finance settlement layer.
