SpaceChain(SPC) is a decentralized space agency with an open network driven by collaboration and transparency through blockchain technology implementation. Upholding the principles of true decentralization and international collaboration within a vibrant global community, SpaceChain leverages the dynamics of tokens and private funding to accelerate space development. SpaceChain was founded in 2017 and has completed the development of the SpaceChain Operating System (SpaceChain OS). SpaceChain OS has been successfully adapted to the Sparc V8 satellite operating system and has achieved stable operations at the system level. SpaceChain OS integrates Qtum blockchain technology and has established a platform for the development of space-based applications. In February 2018, SpaceChain released and launched its first SpaceChain OS blockchain node into space. Through harnessing the power of tokenization, private funding and leadership, SpaceChain provides an opensource platform for innovators around the world to maintain an opportunity to choose and execute projects that fit the blockchain-based philosophy to accelerate outer space development.
