Farcaster is a decentralized SocialFi protocol focused on creating a trusted, neutral social graph network. It allows users to manage their online identities via Ethereum Name Service (ENS), utilizing both the Optimism and Ethereum networks. Unlike traditional social media, where users do not own their digital identities, Farcaster enables users to control and manage their identities securely and anonymously through blockchain technology.

Farcaster operates with a hybrid structure, using both on-chain and off-chain layers. The off-chain layer consists of peer-to-peer Hubs that store user data and handle most user activities, such as posting, following, and interacting with others. The on-chain layer, deployed on Optimism, handles sensitive tasks requiring high security, such as creating accounts, storing data, and adding keys for connected applications.

Users can participate in Farcaster by running their own Hubs, which store and validate off-chain data while syncing with on-chain data from Ethereum. These Hubs ensure the decentralized nature of Farcaster's network, where validators check the authenticity of user actions, such as verifying signatures for posts.

Farcaster was developed by Merkle Manufactory in 2021, led by former Coinbase executives Dan Romero and Varun Srinivasan. It has gained significant backing, raising $30 million in 2022, led by a16z, and later securing $150 million in 2024 from Paradigm and other investors, boosting its valuation to $1 billion.

In summary, Farcaster stands out as a decentralized, blockchain-based social network, offering users true ownership of their digital identities while utilizing a secure, scalable infrastructure.
