Welcome to 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.
Sia is here for good
Not only is your data safe on Sia, but you can feel confident that Sia isn't going anywhere. Sia has been in development for six years and has been live for five. The Sia software has been downloaded over a million times, and thousands of TB have been uploaded to the network since its inception. If the Sia dev team quit tomorrow, the network can autonomously run forever.
Sia has an incredible ecosystem with renters, hosts, miners, and a teeming developer community building on Sia such as the Skynet layer 2 network and enterprise storage service Filebase.
