Decentralized storage networks already hand pieces of people’s data to strangers’ machines. The lasting question across these networks is whether the machine holding the data can read it. A research paper by Gregory Magarshak, a professor at IENYC, describes a system called Safecloud built on one design rule: the nodes that store data see only ciphertext, and the nodes that route data hold no keys.
