Blockchain for Satellites
"In the future, Spacechain is considering a subscription-like model where developers pay for storage space on the satellite and certain functions of the operating system’s API. Creating a token economy with crypto-coins – tentatively dubbed SpaceCash – is another option, though that’s still a work in progress. Generating enough profit to cover satellite maintenance and operating costs will be daunting, but for now, it doesn’t seem to be a top concern.
Spacechain is not alone in its efforts to merge blockchain and satellite technology. Blockstream, a Canadian startup backed by LinkedIn co-founder Reid Hoffman, rolled out its own system in August.
Unlike Spacechain, Blockstream is renting existing satellites, which are farther away from Earth and have more extensive coverage." (https://www.techinasia.com/spacechain-blockstream-blockchain-to-satellite)
