Overview
- Google presented Google Multi-Party Compute at its New York digital assets symposium on Wednesday and said it expects commercial availability in early 2027 pending private-preview results.
- The service uses multi-party computation (MPC) to divide a private key into separate shares so transactions can be signed without ever assembling the full key on one machine.
- A policy engine inside Google Confidential Space evaluates transfer requests against limits, destination rules and approval requirements before any signature is produced.
- Alphabet is already using the system to protect unspecified assets on Ethereum and Solana while several unnamed major financial institutions are in a private preview of the product.
- Key commercial details remain open: Google has not released pricing, named partners, performance benchmarks or a firm launch date beyond the early‑2027 target, and the company says post‑quantum signing support has no announced timetable.
