Sia (SC) offers decentralized cloud storage on the blockchain. It splits apart, encrypts, and distributes your files across a decentralized network. Since you hold the private keys, you own your data. No outside company like Amazon, Google, or Microsoft can access or control your files. Not only is it private and decentralized, it is far more affordable. For instance 1TB is $2 per month with Sia versus $23. Since your files are stored throughout nodes all over the world, you won't have to worry about central commercial server failures. Sia looks to offer in a new era of cloud storage.
