Google Cloud Introduces Multi-Party Compute Crypto Custody Solution Amid Quantum Computing Concerns
Alphabet (GOOGL) has previewed a new crypto custody system called Multi-Party Compute (MPC), designed to protect digital assets by splitting private keys into fragments across separate systems. This move follows research published by Google earlier this year suggesting that Bitcoin's encryption could be more vulnerable to future quantum computing attacks than previously estimated. The MPC service specifically targets banks and institutional clients, aiming to mitigate the theft of private keys, which accounted for nearly 44% of all cryptocurrency theft in 2024. While the product positions itself against long-term quantum threats, its immediate utility is focused on preventing traditional hacking of individual networks. The commercial launch is slated for early 2027. However, market analysts remain cautious regarding Alphabet's potential revenue from this niche service, noting significant competition in the cybersecurity sector and the fact that powerful enough quantum computers may not pose a practical threat for another decade.
