Your data is incomparably safe when you use Sia. Sia is a fully decentralized cloud storage network. It has been operating since 2015, hundreds of terabytes are currently being stored on it, and thousands of terabytes have been stored over the years.
The data normally on Sia gets split up, encrypted, and the pieces are then distributed all around the world to different hosts.
Sia is decentralized, which has a lot of inherent benefits. While we develop the software, we're not in charge of the network. No one is - it's all handled by smart contracts and a blockchain, and so you can make sure we're staying honest.
When you upload your media to Sia, every single file gets divided into 30 segments before uploading, each targeted for distribution to hosts across the world.
File segments are created using , commonly used in CDs and DVDs.
Each file segment is encrypted before being sent out.
Like we mentioned earlier, Sia divides each file into 30 segments before uploading and puts those pieces all over the world on the Sia network. This distribution assures that no one host represents a single point of failure and reinforces overall network uptime and redundancy.
The allows Sia to divide files in a redundant manner, where any 10 of 30 segments can fully recover a user's file.
This means that if 20 out of 30 hosts go offline, a user is still able to download a file. And when hosts go offline, Sia automatically starts to re-duplicate them again. It would take a simultaneous global event to knock out enough hosts to damage the integrity of your files.
And because Sia is decentralized, no one person, company, or government can deny you access. It's global and governed by no one.
Just as important as how it keeps your data secure, is why. The Sia network keeps your data safe because data hosts are financially incentivized to provide enterprise-level service. They earn money by hosting data, so naturally, they want to be good hosts.
