WHO FARCASTER IS AND WHAT IT DOES

Farcaster is a sufficiently decentralized, open-source social network. As an open protocol, it can support many clients, just like email. Users can create profiles, post short messages or "casts", follow others and organize into communities or "channels". The most widely used client, today, is a Twitter/X-like user interface called Warpcast, but many Farcaster clients exist. Clients organize Farcaster in a specific user interface, e.g. the Flint client makes Farcaster's data look similar to Reddit, Farcord make Farcaster datalook similar to Discord, Warpcast and Supercast make Farcaster data look similar to X.

Farcaster is a public social network similar in design to Twitter and Reddit, and aims to become the underlying layer based on which social networks front-ends beyond Twitter and Reddit, from Facebook to Instagram and Snapschat and Tik Tok, will eventually be built.

Farcaster being public and decentralized, anyone can build an app to read and write Farcaster data. Users own their accounts and relationships with other users and are free to move between different apps. Put simply:

• Find your community: Whether you create art, write code, stay fit, or make memes, there's a community here just for you. Farcaster makes it easy for people to find and organize interest-based groups.
• Choose your app: Farcaster has many client apps, just like email. Pick your favorite one, or even use many at the same time. With Farcaster, public data is freely available, and you can always switch between apps.
• Own your audience: No one can take your followers away or shut down your application. A hybrid on-chain and off-chain system ensures that Farcaster remains decentralized while scaling to millions of users.

Faracaster is "sufficiently decentralized" in the sense that a user's identity is registered onchain, but the user's activity (posts or casts, follows, replies, likes, re-casts etc) is stored off chain on a distributed network of servers run by volunteers in order to avoid centralization risk. This design makes Farcaster faster than similar Web3-enabled social network alternatives such as Lens.xyz, as well as cheaper. An introductory video can be found here.
