Also, for the note to function, we will need the satellite to connect to various ground stations around the world so it constantly stays up to date. We could probably set up a network of volunteers who would broadcast and receive data from the satellite and publish it to the internet.
Also, I know an aerospace engineer (rocket scientist) so I will see if I can get him in on this.
Wouldn't the time delay between the satellite node transmitting and the receiver nodes on Earth receiving make the satellite node always out of sync with all Earth base nodes? I'm no electronics/radio expert, but a cubesat couldn't have a very powerful transmitter considering its size. Can tiny transmitters transmit reliably at high speed over vast the distances from orbit back to Earth?
a Full Node requires ~ Internet connection with upload speeds of at least 400 kilobits (50 kilobytes) per second.
a Cubesat can have a very powerful transmitter, it depends on how you build it, a standard Cubesat S-band transmitter Transmission data rates up to 2 Mbps. but there are way more powerful ones which could be used instead.
i've also checked up more on launching. there are apparently way cheaper alternatives then the 120k i mentioned earlier, it seems to depend on the company situation really, and it can carry from 40-120kwoi
I wonder if we can actually get NASA to include it in their CSLI project? If in case we get NASA to get our own cubesat launched, that would drastically decrease the cost of sending the first bitcoin node in space, though I don't know exactly how is the process gonna be.
