Overview
Farcaster is a protocol for building decentralized social networks. It aims to be 'sufficiently decentralized,' meaning that two users can always find each other and communicate even if the rest of the network wants to prevent it.
Key Concepts
- Farcaster ID (FID): A unique, numeric identifier for every user, stored on the Ethereum mainnet (or a Layer 2).
- Hubs: Nodes that store and propagate social data (casts, follows, reactions) in a peer-to-peer network.
- Casts: The equivalent of 'tweets' or 'posts' in the Farcaster ecosystem.
- Channels: Community-specific spaces for discussion, similar to subreddits.
Ecosystem
Farcaster has a growing ecosystem of clients (like Warpcast) and developers building specialized social applications on top of the protocol.
