BitGo, Inc., a regulated digital‑asset custodian, and Singapore‑based Silence Laboratories announced that they have successfully simulated a post‑quantum transaction using multi‑party computation (MPC) wallet infrastructure. The demonstration, held at a private industry event, showcases a quantum‑safe signing approach aimed at banks, custodians, exchanges and other institutional digital‑asset platforms.
BitGo and Silence Laboratories Demonstrate Post‑Quantum MPC Transaction
The collaboration produced the first post‑quantum transaction simulation by a regulated custodian employing an MPC‑based wallet. The live demo used Silence Laboratories’ newly launched PQ‑MPC protocol, which is built on the ML‑DSA digital signature algorithm standardized in NIST’s FIPS 204, together with BitGo’s institutional custody and wallet platform. Researchers and security leaders from Google, Stanford, the Linux Foundation and leading financial institutions attended the event.
Growing Institutional Focus on Quantum‑Resistant Security
Quantum computing is increasingly cited as a planning priority for financial institutions and blockchain networks, even though a cryptographically relevant quantum computer does not yet exist. The announcement notes that “quantum computing has moved from theoretical discussion to an infrastructure planning priority for the digital asset industry,” according to BitGo CEO Mike Belshe. Both companies intend to continue developing and testing the solution with select customers, focusing on interoperability, policy controls, auditability and deployment models suitable for regulated market participants as post‑quantum standards evolve.
Implications for Custody, Treasury and Settlement Workflows
The simulated transaction demonstrated that post‑quantum signing can be incorporated into an institutional wallet workflow while preserving MPC benefits such as distributed key control, policy enforcement and separation of duties. Silence Laboratories CEO Jay Prakash highlighted that many existing digital‑asset systems rely on signature schemes vulnerable to quantum attacks, and that the new PQ‑MPC infrastructure allows institutions to upgrade on their own timeline rather than facing a rushed migration.
Key Takeaways
- BitGo and Silence Laboratories completed the first post‑quantum transaction simulation by a regulated custodian using MPC‑based wallet infrastructure.
- The demo employed Silence Laboratories’ PQ‑MPC protocol built on the NIST‑standardized ML‑DSA algorithm and integrated with BitGo’s custody platform.
- Both firms plan to further develop the solution with select customers, emphasizing interoperability, institutional policy controls and auditability as post‑quantum standards mature.
FinanceInsyte's Take
The joint effort signals that leading custodians are beginning to address quantum‑related risks before practical threats emerge. While the technology remains in a testing phase, the focus on regulatory‑compatible deployment models suggests relevance for institutions that must balance security upgrades with compliance obligations. Executives should monitor the evolution of post‑quantum standards and the availability of interoperable solutions as the ecosystem moves toward broader adoption.
