atproto에는 인스턴스가 없다

atproto and Mastodon represent fundamentally different approaches to decentralized social networks: Mastodon bundles hosting, apps, and user identity within instances, while atproto decouples hosting from app aggregation—similar to RSS and Google Reader. This architectural distinction is crucial because atproto's separation enables genuine user portability and a diverse app ecosystem, while Mastodon's federation model creates strong dependencies and coordination challenges. Understanding this difference reveals how next-generation social platforms may reshape user control and network economics.
