Farcaster is a decentralized social network protocol that allows users to post, interact, and create content without relying on centralized servers or entities. It aims to provide a more open and user-controlled alternative to traditional social media platforms. The protocol is built on a blockchain, which means that posts and interactions are stored in a distributed ledger, enhancing transparency, security, and control for users.

Farcaster enables people to interact with each other across different apps and services that implement the Farcaster protocol, making it interoperable. The focus of Farcaster is on giving users ownership of their data and avoiding the control of any central authority over the content and interactions that take place on the network.
