What happens in the event of a hard fork? Does a Bitkey user have the ability to access both forked versions of the blockchain? I ask because my understanding is the keys are encrypted (one in the iOS app, one in the cloud, and one with Bitkey) and you can't actually see the keys - the Bitkey software/hardware device combo just decrypts them for transacting. If that is the case, unless the Bitkey app allows the users to access both chains in the Bitkey app interface, they can't access them. Is that correct?
