Big banks expand bitcoin custody vaults, but key issue turns to quantum computers

Global big banks are expanding bitcoin custody as a strategic business, but a report warns today’s crypto custody infrastructure could face structural risks in a future quantum-computing era. Swiss digital asset technology company Taurus said major custodians carry significant risk during a shift to quantum-resistant cryptography. It said upgrades require blockchain protocol changes and broad coordination. The report argues MPC may face bigger hurdles than HSM, though the view is contested.
