User: what is nostr
AI: Nostr is a decentralized social network protocol designed for censorship resistance. Here's a breakdown of its key aspects:
* **Protocol:** Nostr operates as a simple, open protocol that relies on relays to store and transmit cryptographically signed events. This design promotes decentralization and censorship resistance.
* **Relays:** Relays are servers that store and distribute Nostr events. Anyone can run a relay, and users can choose which relays to use. Examples include `wss://relay.damus.io` and `wss://nostr-01.yakihonne.com`.
* **Events:** Events are JSON objects containing data like posts, messages, or other interactions. Key fields include:
* `pubkey`: The public key of the user who created the event.
* `content`: The actual content of the event (e.g., the text of a post).
* `created_at`: A timestamp indicating when the event was created.
* `tags`: Metadata attached to the event, such as hashtags or mentions.
Here's an example of a kind:1 event (a text note):
```json
{
"id": "...",
"pubkey": "...",
"created_at": 1678886400,
"kind": 1,
"tags": [["t", "nostr"]],
"content": "Hello Nostr!",
"sig": "..."
}
```
* **Public-Key Cryptography:** Nostr uses public-key cryptography for user identification and authentication. Each user has a public key and a private key. Events are signed using the private key, and this signature can be verified by anyone using the corresponding public key. NIP-07 defines how clients can handle signing on behalf of the user.
* **NIPs (Nostr Implementation Possibilities):** NIPs are proposals for extending or improving the Nostr protocol. Some important NIPs include:
* NIP-01: The basic protocol definition.
* NIP-07: Client-side signing, allowing users to sign events directly from their Nostr clients.
* NIP-22: Smart Widgets, which are interactive components embedded in Nostr events, as used in YakiHonne’s framework for dynamic user interactions. These widgets have a defined size (360px width, max 640px height).
