BlockBeats report: On October 29, Google launched its Google Multi-Party Compute managed platform at the New York Digital Assets Symposium, targeting banks and financial institutions. The platform shards private keys across multiple environments to prevent the full private key from being centralized. Before transaction signing, it can enforce institutional policies to validate spending limits, whitelisted addresses, and multi-party authorization. The service is currently in private preview and is planned for commercial release in early 2027, with several major financial institutions already testing it.
Alphabet has used this technology to protect digital assets on Solana and Ethereum, without disclosing specific holdings or the list of testing institutions. Google stated that Chainalysis data shows that private key compromises accounted for approximately 43.8% of all stolen crypto assets in 2024. The current product is not post-quantum, but its architecture can be extended to incorporate post-quantum cryptography in the future.
