Farcaster is a decentralized social network built on the Ethereum blockchain, organized into three layers:

1. Farcaster ID:
   This layer manages user identity through smart contracts on Optimism. It governs usernames, account information, and cryptographic keys, with names managed both on-chain and off-chain using Farcaster namespaces or Ethereum Name Service (ENS). Each user account is identified by a unique Farcaster ID, linked to their Ethereum address.

2. Farcaster Hub:
   The Hub is a distributed network of nodes that stores user data off-chain to ensure speed and efficiency. These nodes handle user messages (called casts) and synchronize data across the network, maintaining performance and reliability.

3. Farcaster Storage Rent:
   This model allows dApps to build on the data stored in Hubs, expanding the functionality and user experience. Users pay subscription fees to store their data, fostering innovation within the community.

Users create accounts by connecting their Ethereum addresses and selecting usernames (via Farcaster or ENS). They sign and broadcast messages (casts) using private keys, which are validated and stored by the Hubs. These Hubs enable user interactions, such as follows and reactions, ensuring a transparent and secure social network experience.

Farcaster integrates deeply with Ethereum, enabling users to interact with dApps and participate in blockchain activities. The open ecosystem encourages developers to build and integrate their own dApps, enriching the platform’s features and services.

• Warpcast: A Web3 social media app with an interface similar to Twitter/X, available on web and mobile. Users can post casts, interact with others, display NFTs, and track on-chain activities directly in the feed.

• Paragraph: A decentralized publishing platform similar to Substack but with advanced Web3 features. It offers NFT memberships, token gating, detailed analytics, and email automation, allowing creators to monetize content and collaborate with teams.

• Kiwi News: A crypto media dApp where users engage using community NFT cards. Members share links to podcasts, articles, or videos, vote on top content, and access ad-free subscriptions. Kiwi News is available as a web app and browser extension.

Farcaster’s modular architecture and rich ecosystem empower both users and developers, creating a seamless, blockchain-integrated social experience that transcends the limitations of traditional Web2 platforms
