Sia Decentralized Private Cloud by Nebulous Labs

What if you could liberate the unused storage space of the world and unite it into a worldwide free market for data?

Sia is a fully open source cloud storage platform that is user-focused and completely decentralized. Sia exists through a blockchain-based marketplace that allows users to discover and connect to storage providers to store their data.

Instead of giving data to just a single provider, the data is split up, encrypted, and then redundantly stored across dozens of storage providers. This means that no individual storage provider has any amount of control over the data. From day 1, the user has the power.

A blockchain also means that there is no central company controlling the prices, and no terms-of-service or unfriendly privacy policies. It’s a revolutionary way to put your data in the cloud.

The idea of Sia was originally conceived at HackMIT 2013.

Sia leverages the capacity of blockchain technology to enable distributed networks to reach consensus in a secure and trustless way.

Cryptographically secured smart contracts ensure the encryption and transfer of data with no possibility for a third party to interfere in any way.

Sia is a new approach to cloud storage platforms. Instead of all datacenters being owned and operated by a single company, Sia opens the floodgates and allows anyone to make money by renting out their hard drive. Data integrity is protected using redundancy and cryptography.

Breaking into this market is a multi-billion dollar endeavor. The long term goal of Sia is to be the backbone storage layer of the Internet.

We believe data should be free. We aim to liberate the unused bits of the world and construct the largest storage superserver on the planet.

The promise of Sia is a decentralized network of datacenters that, taken together, comprise the world’s fastest, cheapest, and most secure cloud storage platform. Today, being a major cloud storage player requires having datacenters, building trust within the market, reaching customers, and competing with giants such as Amazon, Google, and Microsoft.
