SpaceMint (formerly Spacecoin) is a decentralized open-source cryptocurrency based on the proof-of-space (PoS) algorithm, where mining requires proof of space rather than computation, as, for example, in Bitcoin. This saves energy consumption and also makes it possible to mine coins even if there is no expensive equipment.
In addition, the creators aim to provide digital currency, infrastructure and financial tools for a comfortable life in space. They find it quite possible, due to the use of advanced technology, as well as a powerful community of skilled developers and space experts.
