Quantum-safe signatures for institutional wallets have finally moved from research papers into practical use, with Google and Stanford both testing them out. The countdown for the old signature schemes has begun.

Crypto Jie News reports that Bitgo and Silence Labs have completed a post-quantum MPC transaction simulation, demonstrating the application of quantum-safe signatures in wallet workflows. The test was conducted at a private industry event, with participation from Google, Stanford, the Linux Foundation, and others. The CEOs of both sides stated that quantum computing has become a key focus of infrastructure planning, and that institutions need to prepare without weakening security and control, because the system still relies on older signature schemes, which creates risk.
