Sia is reinventing cloud storage. Our technology connects users who need file storage with hosts worldwide offering underutilized hard drive capacity. Blockchain technology secures their data and enables improved economics for users and hosts.

The Sia blockchain allows this marketplace to run without an intermediary. Sia secures storage transactions with smart contracts, creating a more reliable and affordable offering when compared to traditional cloud providers. No one person or organization can censor or deny access to data—not miners, not developers, nor any government. We believe Sia’s distributed, decentralized storage technology is stronger, more secure, more efficient, and more equitable for the entire ecosystem.
