Sia

Sia is a decentralized cloud storage platform secured by blockchain technology. The Sia storage network leverages underutilized hard drive capacity around the world to create a data storage marketplace that is more reliable and lower cost than traditional cloud storage providers. Sia has its own blockchain, and a utility token that powers it – the Siacoin.

Your data is truly private and gets stored across the globe to eliminate any single point of failure and ensure the highest possible uptime. Since you hold the keys, you own your data. No outside company can access or control your files.

Data cannot be de-platformed. Files can not be hacked.

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.

We believe that neither individuals nor institutions should be beholden to large corporations. Sia was created to promote and safeguard users’ freedoms. It’s our attempt to bring decentralized storage built on blockchain technology to the mainstream without sacrificing price or performance.
