See what powers the Sia network.
Sia makes some bold claims — because no other cloud storage has our design. See for yourself.
How Your File Gets Stored
Sia is a pure decentralized peer-to-peer network. No central access point, no gatekeepers, and no insanely expensive hardware requirements. Why does decentralization matter? It’s the key to how Sia keeps a file safe and sound.

Instead of forcing users to entrust their data to a centralized cloud storage network, we created a new decentralized one that can store — but not see — your data.
At its foundation is a blockchain layer that supports the software above it. This software uses smart contracts to automatically distribute fragmented, encrypted data across a global network of independent storage providers. Data is never stored on the blockchain. Users pay providers for storage using Siacoin.
Non-Profit Model
Sia is an open-source project supported by the nonprofit Sia Foundation and sustained by community donations.
