Starknet challenge drives quantum-safe signature checks down to about $0.023

An open optimization contest backed by StarkWare and the Starknet Foundation roughly halved the gas cost of verifying Falcon-512 signatures That’s the result of an open challenge where people and AI agents compete to make post-quantum signatures cheaper. Within weeks, they cut the gas bill for verifying a Falcon-512 signature roughly in half. The challenge targets Falcon-512, a post-quantum signature scheme. The contest asks a narrow question: how cheaply can a Falcon-512 signature be verified inside Starknet’s Cairo-based environment? The starting line came from OpenZeppelin, which supplied the initial verifier. That baseline implementation consumed 48.4 million gas per verification. The current leading implementation sits at approximately 25.9 million gas . That is close to a 2x improvement, or nearly 50% less work for the network.
