Siacoin

Sia is a decentralized cloud storage platform based on blockchain technology and smart contracts. It created a worldwide storage marketplace, where everybody can rent its hard drive for Sia clients. All hosted information is encrypted, broken in small pieces and sent to different nodes. This process assures high level of data protection and competitive prices. There is no central server which has ownership over your data. Instead of this, a single file can be fragmented and stored on 100 hard drives. You will pay for storage services in Siacoins, native currency of Sia company. Storage providers will also receive Siacoins, which may be exchanged to other currencies.
