Blockstream Launches New Custody System, Adam Back Advocates Simplified Offline Security

Odaily reports: Digital asset infrastructure company Blockstream has launched an institutional digital asset custody solution developed jointly with French technology group Thales, combining Thales hardware security modules with Blockstream's secure multi-party computation technology to execute the full signing protocol within a protected environment on dedicated hardware.

Blockstream co-founder and CEO Adam Back stated that traditional multi-party computation protocols are complex and involve extensive interaction between devices, making them unsuitable for fully offline cold storage. He believes that keeping signing devices offline helps reduce the risk of unauthorized access, and that AI may also help attackers discover subtle vulnerabilities in complex implementations.
