Google Cloud launches MPC service for institutional Bitcoin custody in preview

Google Cloud has introduced a Multi-party Compute (MPC) service currently in preview, designed to allow financial institutions to jointly authorize and sign cryptocurrency transactions without any single party holding the full private key. The service is positioned for institutional Bitcoin custody. Google expanded its Bitcoin security rules on October 1 to evaluate transaction amounts, identify destination address types, and detect change outputs. The MPC Symposium, scheduled for Wednesday in New York, will feature speakers from Morgan Stanley, OKX, Citi, and Wells Fargo.
