FALCON signature verification gas fees dropped from 24M to just 2M. That’s a 12x reduction in cost!

One of the biggest hurdles in PQ cryptography is handling heavy-duty mathematical computations efficiently. ZKnox tackled this by optimizing the Number Theoretic Transform (NTT)—a key operation used in cryptographic algorithms like FALCON (a leading PQ signature scheme).

Some post-quantum methods, such as Falcon signature schemes, provide resistance against quantum computing-enabled attacks, but certain inefficient functions currently make the signatures expensive on Ethereum. ZKNox recently released a more efficient version of one of these functions, the Number Theoretic Transform (NTT), making the Falcon signatures more efficient. "Full FALCON signature verification gas costs have dropped dramatically—from 24M gas down to just 2M," the Ethereum Foundation wrote in an X thread announcing their support of ZKNox. "This significant reduction means that PQ transactions are 12x cheaper on Ethereum!"
