Blockstream and French technology group Thales have launched a custody infrastructure for banks and other large financial institutions in which no single device, employee or complete private key is enough to move bitcoin.
Normally a private key must approve a transaction. For an institution, holding that key whole on one computer or with one person is risky, since theft, an internal error or a hacked system could be enough. The new service spreads signing over several authorized parties. They jointly perform the calculation that produces a valid transaction, without the full key ever being assembled in one place.
Blockstream uses multi-party computation for this, and the whole calculation runs inside Thales hardware security modules, devices designed to shield secret keys from ordinary computer systems. The system also includes FROST, a method that lets several participants create one valid Bitcoin signature, so a bank can require approvals from several teams or sites before a large transaction goes through.
The service becomes part of Blockstream Enterprise, the platform for institutional custody, payments and digital securities. Blockstream says the cooperation with Thales has run for two years and that the business version, previously a limited test, is now officially launched.
The announcement names no banks or asset managers using it and gives no price, supported countries or first deployment. The design lowers the risk that one stolen key is enough, but it does not guarantee that errors, misuse by authorized parties or attacks on other components are impossible. Ordinary crypto wallets are unaffected.
