Blockstream and Thales launch Bitcoin custody system with offline signing
Image: BitcoinistBlockstream has launched an institutional Bitcoin custody system developed with Thales. The system combines Thales hardware security modules with Blockstream's Secure Multi-Party Computation. Blockstream says transaction signing runs inside the hardware security modules, so private keys and key shares do not cross the hardware boundary during signing. The product is delivered through Blockstream Enterprise. Adam Back, Blockstream's co-founder, has argued for offline security as cyberattacks grow more sophisticated.
