Did this project have a fund raiser of any kind?
The CEO of SpaceChain is already a millionaire. He is only in his 20s but started an educational company in china that he got from 0 to 10 Million/year, then he sold it for surely a multiple of that. Now he was looking for what to do with his life and all his money... Then he got mentored by Tim Draper and found his true calling: Bring space exploration forward. Explore the universe. Find out what dark matter is. He, Tim Draper, Jeff Garzik, and a guy who created software and hardware that is being used on the International Space Station funded it, as well as some others.
It is a nonprofit Foundation just like Ethereum is.
They just updated their website and released a whitepaper. I am not a whitepaper expert so I hope some people can give some insight. I usually invest based on the team and execution. Because many have good ideas, few people can execute them well.
The new website looks amazing... http://www.spacechain.com/
