The Sia Foundation

A non-profit organization for the benefit of distributed storage

The Sia Foundation, Inc. is a registered 501(c)(3) non-profit dedicated to revolutionizing data storage through decentralization.

We believe that the success of Sia relies on a positive feedback loop involving:

  • Developers who improve the Sia protocol and create products, tools, and services that support its use.
  • Research that enhances the ability to use Sia and the Sia network for a broader range of data storage.
  • Adoption of Sia as a performant and scalable storage platform
  • Users who are attracted by Sia's utility and the services entrepreneurs build on the Sia network.

Our objectives are to:

  • Support the Sia ecosystem - We aim to provide resources and remove obstacles that discourage developers, entrepreneurs, and others from building, adopting, or supporting Sia.
  • Maintain and Build the Sia network - We aim to create a user-friendly, fast, scalable decentralized storage network through cutting-edge research on peer-to-peer networks, blockchains, and storage protocols.
  • Educate Users - We create content, organize events, and host workshops.

Our GitHub

Our GitHub repos contain the code that powers the Sia network, SDKs that make it easier to interact with it, and open-source extensions we have built on top of it.

The Sia repos are organized by their role in the ecosystem

SiaFoundation/mux

A privacy-focused e2e encrypted connection multiplexer. mux is the default transport for renter-host protocols 3 and 4.

SiaFoundation/core

Provides low-level core types, encoding, transport implementations, and consensus validation code in Go. It contains the primary implementation of Sia's consensus validation.

SiaFoundation/coreutils

Builds on core by providing component implementations such as the p2p syncer, chain manager, and single-address wallet.

SiaFoundation/hostd

The primary storage provider software on the Sia network. Enables users to sell their storage space to consumers.

SiaFoundation/renterd

The primary storage consumption software on the Sia network. Enables users to rent storage from providers. It is designed to be highly customizable, performant, and scalable to fit the needs of the diverse community utilizing the Sia network.

Contributing

As an open-source project, we value all contributions highly. If you're looking for ways to contribute, look for the good-first-issue tag on our repos.
