LLM answer ok?
Nostr, ActivityPub, and the AT Protocol (used by Bluesky) are all decentralized social media protocols, but they differ significantly in their architecture, approach to data storage, and user experience. Nostr focuses on user-led social media with a simple, flexible protocol centered around relays, while ActivityPub powers the Fediverse with federated instances and a more complex structure. The AT Protocol, used by Bluesky, prioritizes account portability and a more structured data model. [1, 1, 2, 2, 3, 3, 4, 5, 6, 7, 8]
Here’s a more detailed breakdown:- Nostr:
• Focus: User-led social media with a focus on decentralization, user control, and censorship resistance. [1, 2]
• Architecture: Relays (servers) handle communication and data relaying. Users connect to multiple relays, and there are no instances in the traditional sense. [9, 10]
• Data Storage: Data is stored across multiple relays, and users can choose which relays to interact with. [9, 10]
• User Experience: Emphasizes simplicity, flexibility, and user autonomy in content and moderation. [2]
• Strengths: Decentralized, censorship-resistant, and adaptable to various use cases. [2, 10]
• Weaknesses: Smaller network compared to ActivityPub and AT Protocol. [7, 10]- ActivityPub:
• Focus: Federated social networking, enabling communication between different instances (servers). [1, 1, 11, 11]
• Architecture: Relies on a network of independently run servers (instances) that federate (exchange data) with each other. [1, 1, 11, 11]
• Data Storage: Each instance stores its own data. [3, 3]
• User Experience: Mimics traditional social media platforms with features like following, liking, and commenting. [11, 11, 12, 12]
• Strengths: Established ecosystem with a large number of users and diverse applications (Mastodon, PeerTube, etc.). [1, 1, 13, 13]
• Weaknesses: Can be more complex than Nostr due to the federated structure, and moderation can vary between instances. [2, 2, 3, 3, 14]- AT Protocol (Bluesky):
• Focus: Account portability and a structured data model. [3, 3, 4, 4, 15]
• Architecture: Uses a layered approach with a data layer (hosted by Bluesky) and a protocol for interacting with that data. [3, 3, 4, 4]
• Data Storage: User data is stored in signed data repositories. [4, 4]
• User Experience: Designed for a more modern and potentially smoother user experience. [3, 3, 4, 4, 16]
• Strengths: Prioritizes account portability and aims for a better user experience. [3, 3, 6, 6]
• Weaknesses: Currently relies on Bluesky for its data layer, raising concerns about centralization. [3, 3]In essence:
ActivityPub
is a mature protocol powering a vast network of federated servers with a wide range of applications.
Nostr
is a simpler, more user-centric protocol focused on decentralization and user control.
AT Protocol
prioritizes account portability and a modern user experience, but is currently more centralized due to its data layer dependence. [2, 3, 3, 5, 6, 6, 7, 17]

I think the main one is that Nostr is supposed to be really simple, and derive some security/privacy from that simplicity. Whereas ATProto and ActivityPub store and forward content so that each rely has a copy, on Nostr nodes the messages are all ephemeral. So it has something of a following with crypto bros and privacy enthusiasts. With nostr IDs are also based on public/private keys unlike ATProto/ActivityPub that use a username@instancename scheme, so signing and identifying content that belongs to a user is easier and more guaranteed to be correct.
