Blockstream announced an institutional digital asset custody solution developed with Thales. The company said it combines Thales hardware security modules with Blockstream’s Secure-MPC technology and keeps the entire transaction-signing process inside the protected hardware.
Blockstream CEO Adam Back said conventional MPC can require too much communication between devices for fully offline cold storage. He argued that offline signing could reduce exposure to unauthorized access, while warning that AI may help attackers find flaws in complex systems.
