PANews reported on March 4 that according to The Block, the Ethereum Foundation announced on the X platform that it has supported the research organization ZKNox, which was founded by three cryptography experts and is committed to developing open source code to improve the security and efficiency of Ethereum, focusing on the field of post-quantum cryptography. Quantum computing threatens all cryptocurrency networks that rely on current encryption standards, although experts disagree on the timetable for feasible attacks. Some post-quantum methods, such as the Falcon signature scheme, provide resistance to quantum computing attacks, but certain inefficient functions currently make these signatures expensive on Ethereum. ZKNox recently released a more efficient version of one of these functions, number theoretic transformation (NTT), making Falcon signatures more efficient.
The Ethereum Foundation wrote in an X post announcing support for ZKNox: "The Gas cost of a full FALCON signature verification has dropped significantly - from 24 million Gas to just 2 million. This significant reduction means that post-quantum transactions on Ethereum are 12 times cheaper." ZKNox's 2025 roadmap includes further development of post-quantum cryptography solutions, as well as providing easy integration with hardware wallet account abstraction, evaluating EIPs that may improve efficiency, and enhancing user security of hardware wallets. It is reported that ZKNox was co-founded by Ledger co-founder and former CTO Bacca Nicolas, former Ledger colleague Dubois Renaud, and experienced cryptographer Masson Simon.
