Hardware Ready Ready to Bench?
On October 28, 2026, Google privately previewed the Multi-Party Compute (MPC) system in New York, a security platform designed for the institutional custody of digital assets. The event took place during the company’s first symposium on digital assets. The technology allows banks and other financial institutions to fragment private keys across separate environments, preventing the complete key from ever being assembled in a single location.
Why it matters
The system positions itself as an alternative to current market providers such as Fireblocks, BitGo, and Fordefi. Google describes the service as a neutral provider for banks requiring scalable infrastructure for tokenization and the management of regulated digital assets. Rich Widmann, director of digital asset strategy at Google Cloud, stated that the adoption of these tools is at an inflection point for financial institutions. The platform combines threshold signatures with policy engines that verify transfers against limits and restrictions before execution.
The numbers
Alphabet already uses the system to protect its own digital assets on Ethereum and Solana. Planned security configurations include approval thresholds such as “two out of three” or “five out of seven.” According to data cited by Chainalysis, in 2024, 43.8% of stolen cryptocurrencies was attributable to compromised private keys. DeFiLlama estimated total losses from hacks at $16.69 billion up to June, with approximately 40% due to key compromise. Google researchers also estimated that a sufficiently powerful quantum computer would take about 9 minutes to derive a Bitcoin private key from an exposed public key.
What remains to be seen
The general commercial availability of the service is planned for early 2027. At present, Google has not disclosed the pricing of the service nor the specific timeline for adopting post-quantum signatures, although the architecture is designed to support them in the future without requiring institutions to rebuild their systems. The banks and initial partners testing the system in private phase have not been officially named by available sources.
