At first glance, an out-of-this-world plan to launch a network of crypto satellites into space, sounds like one of those grandiose ideas that never got much further than a vague outline in an ICO white paper back in 2017. But when the plan comes from a team including a Google X engineer and the co-founder of the first private mission to reach the moon, the project suddenly seems a lot more feasible. The idea behind CryptoSat — which was indeed first outlined in a November 2017 paper — is to build a prototype nano-satellite the size of a coffee mug and launch it into outer space, where it can act as a perfectly isolated and secure cryptographic module.
