ファーキャスター (Farcaster)
『十分に分散化された』ソーシャル・ネットワーキング。
Farcaster is a 'sufficiently decentralized' protocol where users own their accounts and data. It uses an off-chain 'Hub' system for high-speed social interactions (like posting and liking) while keeping critical identity data on the Ethereum blockchain. This balance allows it to feel as fast as traditional apps while maintaining Web3 security.

🧒 5歳でもわかるように説明
Farcaster is like a new version of the internet for social apps. You have one account that works on any Farcaster app (like Warpcast), and no one—not even the people who made it—can delete your account or shadowban you without cause.
🤓 Expert Deep Dive
Employs an architecture of 'Registry' smart contracts on Optimism (Ethereum L2) for identity and 'Hubs' (off-chain, peer-to-peer servers) for data storage and replication. It uses EIP-712 signatures for all user actions.
