Farcaster

Farcaster is a decentralized social network protocol that allows users to own their social identity and data rather than being dependent on centralized platforms like Twitter or Facebook. Users connect their cryptocurrency wallets to create profiles and can move their follower networks and content between different Farcaster-based applications. Domains play an important role in Farcaster and similar protocols as human-readable identifiers that can represent social identities. A tokenized domain like alice.eth can serve as both a Web3 identity and a Farcaster username, creating unified digital identity across multiple decentralized platforms while maintaining user ownership and portability.
