The system, says Hamilton, is designed to be “anti-fragile,” that means it relies on no celebration’s good will to attain its finish. No one however the originator and recipient have entry to the contents of the file, all different events are financially incentivized to cooperate, and redundancies make sure the payload is at all times out there. “Little strings of information management our lives,” says Hamilton. As a result of people are “gooey”—that’s, unreliable and vulnerable to errors—the one smart safety for these strings is cryptography, he provides.
There are numerous different methods, says Hamilton, that Sarcophagus may be utilized outdoors of a crypto setting. A digital useless man’s swap might be utilized by a whistleblower to launch incriminating materials or by a dissident or journalist who suspects a menace to their life, as a form of SOS. In a extra mundane context, it might be used to move account credentials from one era of staff to the subsequent.

Sarcophagus has obtained $6 million in funding so far from buyers together with Placeholder, Blockchange, and Hinge Capital. The mission is managed by a decentralized autonomous group, or DAO—a collective that governs the Sarcophagus treasury and growth course of by a system of group voting. In its current state, Sarcophagus is greatest described as an “early beta,” says Hamilton. The service is operational however not broadly used, and it doesn’t generate vital income—solely a small lower of each cost.
One barrier to broader adoption is that recipients should have already got entry to a crypto pockets, whose credentials are used to decrypt the info payload. There may be an choice to create a brand new pockets for somebody, together with a PDF strolling them by the method for accessing it, however a degree of crypto literacy will surely assist.
Because the era of individuals comfy with crypto grows older and begins to reckon extra significantly with their mortality, Hamilton thinks a bigger subset will start to know the necessity for a service like Sarcophagus. “Millennials are simply beginning to consider this downside,” he says. Hamilton imagines that extra accessible providers will probably be constructed atop Sarcophagus know-how, too. These “boomer merchandise,” as Hamilton calls them, considered one of which his personal crew is creating, will summary away a few of the technical complexity, such that folks received’t notice they’re utilizing crypto infrastructure. (Though there’s an inevitable trade-off between safety and comfort.)
In any case, says Hamilton, the current system—whereby credentials to high-value crypto wallets may be saved in financial institution vaults protected by armed guards—approaches the absurd. The “billion-dollar file cupboard” has to go, says Hamilton. “We’re nonetheless counting on heavy steel doorways and guys with weapons when cryptography itself can act as a metal wall of unimaginable thickness.”
