Blockstream Launches New Custody System, Adam Back Emphasizes Offline Security Simplification

By: cointelegraph.com|11/13/2026 21:56:27

Blockstream has launched an institutional digital asset custody solution developed in collaboration with Thales, combining Thales hardware security modules with Blockstream's secure multiparty computation technology to execute complete signing protocols within a dedicated hardware-protected environment. Blockstream CEO Adam Back stated that traditional multiparty computation protocols are complex and involve significant interaction between devices, making them unsuitable for fully offline cold storage. He believes that offline storage of signing devices helps reduce the risk of unauthorized access, and AI could assist attackers in identifying subtle vulnerabilities in complex implementations.
