A researcher at StarkWare has published an open-source scheme for making Bitcoin transactions resistant to quantum computing attacks using only the network's existing consensus rules — requiring no softfork, no protocol upgrade, and no community-wide coordination.
The project, called Quantum Safe Bitcoin (QSB), was released on GitHub by Avihu Levy, StarkWare's chief product officer and a leading Bitcoin researcher at the firm who previously co-authored ColliderScript, a protocol for enabling stateful computation on Bitcoin without consensus changes. Levy also co-authored BIP-360, the quantum-resistant address proposal that was merged into Bitcoin's official BIP repository in February — a proposal that, unlike QSB, would require a softfork.
"StarkWare has some of the best hackers on the planet," Eric Wall, co-founder of Taproot Wizards and board member of the Starknet Foundation, wrote on X. "It is beautiful to see when hackers use their powers for good."
