WHY SIA

## Our network design unlocks radically unique benefits.

Get Started

##### Decentralized Design
Others claim it — but we built it. Sia network has no central access point, no gatekeepers, and no expensive hardware requirements.

##### Supreme Privacy
Sia stores—but never sees—your data. It splits each file into tiny encrypted shards, jumbles them up, and then distributes them across our decentralized network.

##### Impenetrable Security
We render bad actors impossible, or cosmically improbable, with insurmountable security layers and knowledge asymmetries.

##### Continuous Performance
Our design enables distributed workloads and parallel retrieval — making it faster, more resilient, and outage-proof.

##### Non-profit Model
An open source project sustained by community donations, Sia is free from profit motives and works for the public good.

##### Wait?! There’s a problem with traditional storage?
