[Blockstream and Thales Partner to Launch Institutional Digital Asset Custody Solution] Bitcoin infrastructure company Blockstream and French technology group Thales have partnered to launch an institutional digital asset custody solution. This solution combines Thales' hardware security module with Blockstream's secure multi-party computation (MPC) technology, executing the full signature protocol within the protected environment of the hardware security module. Adam Back: Traditional MPC protocols are complex and require frequent device communication, making them unsuitable for fully offline cold storage; institutions should use cold storage to reduce the risk of cyberattacks and potential AI-assisted attacks.
