Nostr Guides: What is the Outbox Model?

Nostr is a decentralized network with complex interactions among users, bots, topics, and relays, and finding specific content within this system is challenging. The process involves two main components: defining what users are looking for and finding the right relay to serve the content. However, relay selection is difficult because relying on a small set of popular relays can result in missing content or censorship, and random relay selection leads to centralization.

The Outbox Model, introduced by NIP 65, addresses this issue by allowing users to select "read" and "write" relays based on content types. This model improves content retrieval by directing queries to specific relays, reducing data transfer and connections, but it still requires the correct relay list setup, which isn't always guaranteed.

The model's effectiveness depends on reliable relay selections, which are impacted by factors like geographic proximity, content retention policies, and censorship. While Outbox is not a complete solution for all types of content or use cases, it offers a framework for more efficient relay selection and content indexing. Future developments might involve specialized clients or relay proxies to improve the user experience.

The Nostr Outbox Model (NIP-65) allows users to define which relays they want to use for sending notes directly within their profile, improving efficiency and relay management. By declaring this in a special event kind via their profile relay settings, users set preferences on where their events should be sent. This reduces user confusion and fuels decentralization.

The simplest take away here is that users no longer need to have a shared common relay between them to communicate. Clients handle all of the heavy lifting for them. This change simplifies both the client experience and relay coordination, aligning with decentralized social networking principles.

With the Outbox Model, users can use a variety of small and community relays, and still communicate with one another.
