ZKNox Founder: Reducing the verification cost of quantum-resistant Falcon signatures by 12 times, making hardware wallets affordable for access to quantum-resistant systems.

ME News update: On April 2 (UTC+8), Nicolas Bacca (btchip), founder of the research organization ZKNox supported by the Ethereum Foundation and former co-founder and Chief Technology Officer of Ledger, presented technical progress on deeply integrating hardware wallets with Ethereum at EthCC[9]. He noted that, because the EVM natively does not support certain efficient cryptographic signature schemes and complex verification logic, hardware wallets have long struggled to achieve perfect compatibility with the advanced features brought by account abstraction. ZKNox 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 12x—bringing the transaction costs for users to generate post-quantum secure signatures via a hardware wallet close to that of ordinary transactions. At the same time, ZKNox is developing a standardized SDK to support account abstraction features such as seamless compatibility for social recovery, multisig, and complex permission management on hardware wallets, and it is exploring generating zero-knowledge proofs on the hardware device side to verify the legitimacy of signatures on-chain without exposing sensitive information. Nicolas said ZKNox’s goal is to establish open-source hardware security standards, so that hardware wallets can become a universal anti-quantum digital identity signature device across L2s and application scenarios.
