Blockstream and Thales have jointly launched a Bitcoin custody system that secures keys offline using Thales hardware security modules combined with Blockstream's Secure Multi-Party Computation technology. This system targets institutional users like custodial banks and prime brokers, emphasising simpler, hardware-isolated security models to better defend against increasingly sophisticated AI-driven cyberattacks.
