Since Bitcoin is the "currency of the internet" and the internet can be accessed with a satellite, could Bitcoin become the first interplanetary currency (in the Solar System, at least)?
If we had people living on the moon, you could send them funds instantly regardless of their country of origin, account status, etc.
It could be done. I mean through radio waves you can transmit/broadcast the blocks where necessary.
If you put earth the center of the hub, then its very possible. However mining from Mars is not very likely since if the hub is on Earth, the chance of finding a block, on Mars is impossible since by the time you transmit the info back to Earth, you will have a disadvantage because of the distance and time it takes for Lightspeed to arrive to Earth.
