Google Cloud is building a service that lets financial institutions approve and sign crypto transactions together. No single party would control the full private key.
Cointelegraph reports that Google Cloud detailed its Multi-party Compute (MPC) service in documentation updated on Monday. The documentation positions the product for institutional Bitcoin custody. It is still in preview. That means Google provides it as is, with potentially limited support.
Launch Planned for Early 2027
Google Cloud aims to make its MPC Key Management Service generally available in early 2027, a company spokesperson told Cointelegraph.
The service’s release notes go back to August 2026. On Oct. 1, Google expanded its Bitcoin security rules. They now assess transaction amounts, identify destination address types and detect change outputs.
Symposium Draws Banks and Exchanges
The documentation update came just before Google Cloud’s MPC Symposium in New York on Wednesday. The event description promises a first look at Google’s latest MPC products and research projects. Speakers include representatives from Morgan Stanley, OKX, Citi and Wells Fargo.
Earlier Work on Secure Computing
The Alphabet subsidiary has explored related technology before. A June blog post described Confidential Space, a cloud environment built to support secure multi-party computation and data sharing.
