Welcome to Sia

Sia is decentralized, peer-to-peer cloud storage with no central provider and no gatekeepers. Files are encrypted on your own device before upload, so no storage provider can read your data, and you hold the keys. The network is developed by a non-profit and runs on open-source software.

Whether you're a developer building on Sia or a user storing your own data, these docs cover how to use the network.

Where to start

• Store your data — the simplest way to start is the Sia Storage app with a free Sia Storage account (50 GB). For how it works, see About Storing Your Data.

• Provide storage and earn Siacoin — set up hostd.

• Hold and manage Siacoin — use walletd.

• Build an application on Sia — see the Sia Developer Portal.

• Not sure which software you need? — Which Sia software do I need?
