The service splits private keys into fragments that are stored in separate environments – for example, a bank keeps one share on its own hardware, another on Google Cloud, and a third with a different provider. Google says it cannot access the unencrypted shares, eliminating a single point of failure that has caused large‑scale losses in the crypto sector. Commercial availability is planned for early 2027, and Alphabet is already using the technology for its own assets on Ethereum and Solana.\n\nThe launch comes amid growing concerns that AI‑driven tools and future quantum computers could undermine current cryptographic safeguards. Researchers recently uncovered a bug in the XRP Ledger, and Ethereum co‑founder Vitalik Buterin warned that AI‑accelerated mathematics could weaken lattice‑based cryptography within two years. Roughly 6.9 million Bitcoin are considered potentially vulnerable because their public keys are exposed. Google positions its MPC system as a defense against both sophisticated cyber‑attacks and emerging AI and quantum threats.","keyPoints":["Google is previewing an MPC‑based crypto custody system for banks, with commercial rollout slated for early 2027.","The system fragments private keys across separate environments, ensuring Google cannot read them in unencrypted form.","Researchers and Vitalik Buterin warn AI‑accelerated math could threaten lattice‑based cryptography within two years, with about 6.9 million Bitcoin exposed."],"whyItMatters":"The solution gives financial institutions a way to protect digital assets from AI‑driven hacks and future quantum attacks, addressing a critical security gap in the crypto ecosystem.","category":{"slug":"enterprise","name":"Enterprise & Industry","url":"https://digestai.news/category/enterprise"},"entities":{"companies":["Google"],"models":[],"people":["Vitalik Buterin"]},"firstPublishedAt":"2026-10-28T04:00:00Z","updatedAt":"2026-10-28T04:00:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"finance.yahoo.com","title":"Google to Launch Crypto Custody Security System as AI & Quantum Threats Grow","url":"https://finance.yahoo.com/markets/crypto/articles/google-launch-crypto-custody-security-124736951.html","publishedAt":"2026-10-28T04:00:00Z","type":"press","primary":false,"lead":true}],"sourceNotes":null,"discussions":[],"thread":null,"cite":{"text":"Digest AI, \"Google to launch crypto custody security system using MPC in early 2027\", 28 October 2026, https://digestai.news/story/google-to-launch-crypto-custody-security-system-using-mpc-in-early-202","publisher":"Digest AI","title":"Google to launch crypto custody security system using MPC in early 2027","datePublished":"2026-10-28T04:00:00Z","url":"https://digestai.news/story/google-to-launch-crypto-custody-security-system-using-mpc-in-early-202"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
