Cancoin wallets use multi-signature (P2SH) transaction signing that uses multiple private keys (signatures) to unlock your bitcoins and send them. Using a multi-signature wallet creates a decentralized signing process and 'no single point of failure' security.
Cancoin controls a signing (private) key on our Ledger Hardware Security Module (HSM) secured servers, and the user controls a signing (private) key that is privately backed up or secured. A transaction can be made only when these two keys are combined and sent, ensuring total security for the user.
