Project Description

Farcaster is a decentralized social media protocol based on blockchain technology, focusing on interoperability, user autonomy, and privacy protection. Unlike traditional social networks, Farcaster does not rely on central servers but is built on the Optimism blockchain infrastructure. This allows developers to leverage pre-built smart contract functionalities to create diverse decentralized social media applications, ensuring transparency, security, and decentralization.

Farcaster aims to create a censorship-free environment where users have complete control over their data and audience. With a sufficiently decentralized network architecture, Farcaster allows users to control their social graph and interact across different applications on the network through a single identity. This platform functions like a unified space, connecting social apps similar to Instagram and Facebook through a decentralized ID. Even if an application imposes restrictions, users retain their identity and can seamlessly migrate their connections to other applications on the network. Additionally, Farcaster is open source and permissionless, enabling anyone to build applications through API access or other integrations.

Since its launch, Farcaster has attracted over 200,000 users, including notable figures such as Vitalik Buterin and Base Network founder Jesse Pollack. The project’s total revenue has surpassed $1.2 million, currently standing at $1,229,371.

Working principle

Farcaster’s operational mechanism utilizes a hybrid architecture, combining on-chain and off-chain systems to provide a consistent and efficient environment. Here is a detailed breakdown of its components:

Registry Contracts

Farcaster deploys immutable contracts with a limited lifespan on Ethereum’s Layer 2 network (Layer 2 OP Mainnet). These contracts primarily serve three functions:

ID Registration: Generates key pairs linked to Ethereum addresses for newly created Farcaster accounts. Storage Registration: Leases and tracks storage units allocated to each account and collects annual fees. Key Registration: Allows users to authorize and revoke account ownership, enabling them to write and sign messages on their behalf.

Hubs

Hubs are servers running on standard hardware that provide low-level, high-performance data flow within the network. They are responsible for hashing messages and verifying their signatures against the registry contracts. Once verified, all messages are stored in collections and propagated among other Hubs on the network to replicate the data. This off-chain server implementation ensures fast and reliable data access, supporting real-time application development.

Usernames

Farcaster’s usernames are similar to user handles in typical social media applications, used to identify or mention accounts. Farcaster supports two types of ENS names that users can link to their accounts:

Fnames: Off-chain ENS names issued for free by Farcaster. ETH Names: On-chain domain names controlled by users, supporting applications built on the Ethereum network.

These mechanisms enable users to customize their accounts, providing a personalized user experience and facilitating connections with others. By combining on-chain and off-chain operations, Farcaster offers a flexible, efficient, and secure decentralized social media platform for developers and users.
