Google Cloud is progressing with a preview service that lets financial institutions jointly authorize and sign cryptocurrency transactions without granting any single party control over the full private key, according to documentation updated Monday. The Multi-party Compute (MPC) service targets institutional Bitcoin custody and remains in preview with potentially limited support.
This documentation update precedes Google Cloud‘s MPC Symposium in New York on Wednesday, which promises an “exclusive revealing of Google’s frontier MPC product and research projects,” according to its description. The event features speakers from Morgan Stanley, OKX, Citi, and Wells Fargo.
On Oct. 1, Google expanded its Bitcoin security rules to evaluate transaction amounts, identify destination address types, and detect change outputs. The Alphabet subsidiary has previously explored related technology through Confidential Space, a cloud environment designed to support secure multi-party computation and data sharing.
Cointelegraph contacted Google Cloud and Rich Widmann, Google’s director of digital assets strategy, for clarification on the service’s availability and launch timeline.
