Sarcophagus Is a Dead Man’s Switch for Your Crypto Wallet
By combining a century-old idea with cryptocurrency tech, Sarcophagus aims to create a foolproof way to send messages from beyond the grave.
As chronicled in Uptown, Downtown, a 1976 book by Stan Fischler, Luciano was defeated by the confusing braking system, and the train derailed on a jinking set of curves, killing at least 93 people and injuring hundreds more. A dead man’s switch can take the form of a handle or pedal to which force must be continuously applied, or a button that has to be pressed at intervals, but the principle is the same: If the human operator fails to respond, the machine shuts down. The primary difference is that Sarcophagus is built atop crypto technology, meaning the contents of users’ documents are never visible to a third party and that the availability of their payloads does not depend on the service provider remaining in operation.
