Google Cloud has detailed a preview Bitcoin custody service that lets institutions sign transactions without any one party controlling the full private key. The service uses multi-party computation, or MPC, to distribute signing control.
Why it matters
Institutional custody must protect assets while allowing authorized transactions. MPC is designed to avoid placing the complete key in one party's hands, reducing reliance on a single point of control.
Market impact
The preview adds Google Cloud to efforts to build institutional infrastructure around Bitcoin. The announcement signals continued work on custody tools, but provides no details on availability or adoption.
