nice, i just saw it too but you beat me in posting it faster
here is the direct link
http://www.spacechain.com/SpaceChain-0128-1.0-EN.pdfalready am browing thru it...
they will have smart contracts too thru qtum and eth. so maybe they will partner with eth at some point
i also like how the spacechain satellites actually stay up 5 years. some other efficient satellites only stay up one year and that worried me a bit.
essentially, this will bring space exploration forward, and i can see many ways this will explode. like there never has been a standart
OS for space, so now everyone can basically work together and not work with ancient hardware/software anymore, or have to code
every solution on their own. students, univiersities, scientists, commercial space companies and even government space agencies
can use this to be more efficient, have more manpower available, new technologies available.....
and i will be happy to be one of the first to telnet or ftp into space and store data there, maybe use a chat app or even program some
little app to take pictures or record audio, possible one day be able to launch my own little "space drone" to fly out into space and
control it thru spacechain.
