SAVE is a decentralized cloud storage platform and programmable blockchain utilizing blockchain technology. Compared to traditional cloud storage methods, the decentralized SAVE system makes cloud storage more secure, faster, and lower cost. Through erasure coding, encryption, and blockchain technology, SAVE not only offers traditional cloud storage functions but also addresses the security and privacy issues associated with conventional cloud storage. Servers providing storage space receive the native tokens of the SAVE system, incentivizing more idle space to become storage providers.
