ZKNox Founder: Reducing the verification cost of quantum-resistant Falcon signatures by 12 times, hardware wallets are expected to access quantum-resistant systems at an affordable price

ME News message, April 2 (UTC+8): At EthCC[9], Nicolas Bacca (btchip), founder of ZKNox, a research institution supported by the Ethereum Foundation, and the former co-founder and CTO of Ledger, introduced technical progress in deeply integrating hardware wallets with Ethereum. He noted that because the EVM natively does not support certain efficient cryptographic signatures and complex verification logic, hardware wallets have long struggled to perfectly support advanced features brought by account abstraction. ZKNox has reduced the on-chain verification cost of its anti-quantum Falcon signature scheme from 24 million Gas to 2 million Gas—an efficiency improvement of about 12 times—so that the transaction cost for users to generate post-quantum secure signatures via hardware wallets is close to that of ordinary transactions.

At the same time, ZKNox is developing a standardized SDK to support seamless compatibility of hardware wallets with account abstraction features such as social recovery, multi-signature, and complex permission management. It is also exploring generating zero-knowledge proofs on hardware devices to verify the validity of signatures on-chain without exposing sensitive information. Nicolas said ZKNox’s goal is to establish an open-source hardware security standard, making hardware wallets universal anti-quantum digital identity signature devices across L2 and application scenarios.
