The system, says Hamilton, is designed to be “anti-fragile,” that means it is determined by 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 liable to errors—the one wise safety for these strings is cryptography, he provides.
There are numerous different methods, says Hamilton, that Sarcophagus could 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 risk to their life, as a form of SOS. In a extra mundane context, it might be used to cross account credentials from one technology of staff to the subsequent.

Sarcophagus has acquired $6 million in funding to this point from traders together with Placeholder, Blockchange, and Hinge Capital. The venture is managed by a decentralized autonomous group, or DAO—a collective that governs the Sarcophagus treasury and improvement course of by a system of neighborhood voting. In its current state, Sarcophagus is finest described as an “early beta,” says Hamilton. The service is operational however not broadly used, and it doesn’t generate important income—solely a small reduce of each fee.
One barrier to broader adoption is that recipients should have already got entry to a crypto pockets, whose credentials are used to decrypt the information payload. There’s an choice to create a brand new pockets for somebody, together with a PDF strolling them by the method for accessing it, however a stage of crypto literacy would definitely assist.
Because the technology of individuals comfy with crypto grows older and begins to reckon extra critically 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 shall be constructed atop Sarcophagus expertise, too. These “boomer merchandise,” as Hamilton calls them, certainly one of which his personal crew is growing, will summary away a number of the technical complexity, such that folks received’t notice they’re utilizing crypto infrastructure. (Though there may be an inevitable trade-off between safety and comfort.)
In any case, says Hamilton, the current system—whereby credentials to high-value crypto wallets could 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 metallic doorways and guys with weapons when cryptography itself can act as a metal wall of unbelievable thickness.”
