Cours de Sarcophagus

Sarcophagus is a blockchain-enabled, general-purpose digital dead man’s switch. It is autonomous, censorship resistant and immutable. We rely on modern smart contracting networks like Ethereum or Tezos as well as Arweave’s permanent file storage network; files you place in a sarcophagus are only unlocked in the event of you failing to attest to the contract.

Historically, dead man’s switches have been used in heavy machinery to ensure the operator is paying attention and is present at their post. However, there are many other examples of physical-use cases such as suicide bomber vests and even Russia’s Strangelovian Dead Hand nuclear program.
