Farcaster is a decentralized social media protocol built on blockchain technology, focusing on interoperability, user autonomy, and privacy protection. Unlike traditional social networks, Farcaster operates without central servers, leveraging the Optimism blockchain to enable developers to create diverse decentralized applications (dApps) with transparency, security, and decentralization at their core.
1. Project Overview
Farcaster empowers users with full control over their data and audience, fostering a censorship-resistant environment. Its decentralized architecture allows users to manage their social graphs and interact across multiple apps using a single identity. This unified approach resembles linking platforms like Instagram and Facebook under one decentralized ID, ensuring users retain their identity even if individual apps impose restrictions.
Key highlights:
– Open-source & permissionless: Developers can build apps via APIs.
– Growing adoption: Over 200,000 users, including Ethereum co-founder Vitalik Buterin and Base Network creator Jesse Pollack.
– Revenue: $1.2M+ generated to date.

2. How Farcaster Works
Farcaster combines on-chain and off-chain systems for efficiency:
2.1 Registry Contracts
Deployed on Ethereum’s Layer 2 (OP Mainnet), these contracts handle:
– ID Registration: Generates cryptographic keys linked to Ethereum addresses.
– Storage Registration: Leases storage units for an annual fee.
– Key Management: Allows users to authorize/revoke account access.
2.2 Hubs
Decentralized servers that:
– Validate and replicate user messages across the network.
– Enable real-time data access for apps.
2.3 Usernames
Two types of ENS-compatible handles:
– Fnames: Free, off-chain usernames issued by Farcaster.
– eth names: User-controlled, on-chain domains.
3. Core Features
3.1 Frames
Embeddable mini-apps within posts for:
– NFT minting/trading.
– Interactive games and polls.
– Direct shopping or content subscriptions.
Tech: Smart contracts ensure security and seamless integration.
3.2 Warpcast
Farcaster’s flagship client with Twitter-like features:
– Casts: 320-character posts.
– Reactions & Direct Messages.
– Warps: Internal credits for channel creation or tipping.
