ZKNox Founder: Reducing the verification cost of anti-quantum Falcon signatures by 12 times; hardware wallets are expected to connect to an anti-quantum ecosystem at an affordable price

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, an approximately 12-fold efficiency improvement, making the cost for users to generate quantum-safe signatures with hardware wallets nearly the same as regular transactions. ZKNox is also developing a standardized SDK to support seamless hardware wallet compatibility with social recovery, multi-signature, and complex permission management features of account abstraction, and exploring the generation of 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.
