Spacechain is a great example of a company using blockchain and cryptocurrency to build the next level infrastructure that will lower the barriers of entry to the space industry. Their blockchain based software will allow the first multiple tenant satellites. To put this in perspective, if anyone currently wants to run software on a satellite, they have to put their own up or pay someone else to do it. Needless to say, the cost is exorbitant. What they are on the way to doing is reducing the cost of running software in space by 10,000 fold. This will pave the way for a new ecosystem of space based systems.
