ZKNox Founder: Lowering the verification cost of quantum-resistant Falcon signatures by 12 times, with hardware wallets expected to be affordably connected to quantum-resistant systems

ME News Report, April 2nd (UTC+8), Ethereum Foundation-supported research organization ZKNox founder, former Ledger co-founder and CTO Nicolas Bacca (btchip) introduced the technical progress of deep integration between hardware wallets and Ethereum at EthCC[9]. He pointed out that because the EVM natively does not support some 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 the quantum-resistant Falcon signature scheme from 24 million Gas to 2 million Gas, improving efficiency by about 12 times, making the cost for users to generate quantum-safe signatures with hardware wallets for transactions close to that of ordinary transactions. ZKNox is also developing a standardized SDK to support seamless hardware wallet compatibility with account abstraction features such as social recovery, multi-signature, and complex permission management, and exploring generating zero-knowledge proofs on hardware devices to verify signature validity on-chain without exposing sensitive information. Nicolas stated that ZKNox aims to establish an open-source hardware security standard, making hardware wallets a universal quantum-resistant digital identity signer across Layer 2 solutions and application scenarios.
