Google Cloud Announces MPC Service for Institutional Bitcoin Custody

WHY IT MATTERS

When you own Bitcoin, you control it through a private key — think of it like a master password to a digital safe. If someone steals that key, they can take your Bitcoin. For large institutions managing millions or billions of dollars in crypto, protecting that key is critical. Multi-party computation, or MPC, is a technique that splits the key into pieces held by different parties, so no single person or system ever has the complete key. Google Cloud, one of the world's biggest technology platforms, is now offering this kind of service to institutions. This matters because when major technology companies build tools for crypto custody, it can make it easier and potentially safer for large organizations like banks and investment funds to hold Bitcoin, which could affect how widely crypto is used in traditional finance.
