Farcaster is a community-created protocol for building decentralized social applications.

Developers can use Farcaster to build new, decentralized social networks, letting the protocol deal with the hard problems of managing user identities and data. Users can create a new account that they control and sign up to use any of these applications. Users are always in control of their data and identity and can switch freely between applications.

Farcaster is currently in early beta and user registrations are invite-only to ensure that the network remains stable. A community curated list of Farcaster applications and utilities is available in the awesome-farcaster repository.

Invites can be requested in one of two ways:

1. By messaging @dwr on Twitter.
2. By running a Farcaster Testnet Hub, and posting your peer id in the dev channel.

The fastest way to get up to speed on the protocol is by watching the video series.

If you want to dig deeper, we also recommend that you:

1. Read the overview for a high-level picture of the problems, goals and design.
2. Review proposals, for historical context behind some of our design decisions.
3. Take a look at Hubble, an implementation of a Farcaster Hub.
4. Review the smart contracts on the Ethereum blockchain.
5. Dive into the specifications to understand the low-level details.
