Post-quantum cryptography (PQC), like Falcon signature schemes, are designed to withstand quantum attacks, but their current inefficiencies make signatures costly on Ethereum

ZKNox was established on Feb, 2025 by 3 cryptology experts focusing on developing open source code that improves Ethereum security and efficiency, with a special focus on post-quantum cryptography

ZKNox has anounced that it has already optimized the Falcon signature encryption method, a post-quantum cryptography solution, by reducing verification gas costs on Ethereum from 24M to 2M, making transactions 12 times cheaper

The Ethereum Foundation has backed startup ZKNox, which seeks to develop post-quantum cryptography (PQC) for the Ethereum ecosystem

Cryptography, including protocols securing blockchain networks like Ethereum, faces risks from emerging quantum computing technologies, whose ability to perform complex calculations in parallel makes traditional encryption methods vulnerable
