A "list" event is defined as having a list of public and/or private tags. Public tags will be listed in the event `tags`. Private tags will be encrypted in the event `content`. Encryption for private tags will use [NIP-04 - Encrypted Direct Message](04.md) encryption, using the list author's private and public key for the shared secret. A distinct event kind should be used for each list type created. This NIP defines lists of things that users can create. Lists can contain references to anything, and these references can be **public** or **private**.
If a list should only be defined once per user (like the "mute" list) the list is declared as a _replaceable event_. These lists may be referred to as "replaceable lists". Otherwise, the list is a _parameterized replaceable event_ and the list name will be used as the `d` tag. These lists may be referred to as "parameterized replaceable lists". Public items in a list are specified in the event `tags` array, while private items are specified in a JSON array that mimics the structure of the event `tags` array, but stringified and encrypted using the same scheme from [NIP-04](04.md) (the shared key is computed using the author's public and private key) and stored in the `.content`.
## Replaceable List Event Example ## Generic lists
Lets say a user wants to create a 'Mute' list and has keys: The kinds `30000` and `30001` have been reserved for generic lists. These must be accompanied by a `d` tag identifying the list, but these are generally client-specific, except in the standard cases specified below.
```
priv: fb505c65d4df950f5d28c9e4d285ee12ffaf315deef1fc24e3c7cd1e7e35f2b1
pub: b1a5c93edcc8d586566fde53a20bdb50049a97b15483cb763854e57016e0fa3d
```
The user wants to publicly include these users:
```json ## Standard lists
["p", "3bf0c63fcb93463407af97a5e5ee64fa883d107ef9e558472c4eb9aaaefa459d"],
["p", "32e1827635450ebb3c5a7d12c1f8e7b2b514439ac10a67eef3d9fd9c5c68e245"]
```
and privately include these users (below is the JSON that would be encrypted and placed in the event content):
```json | name | kind | "d" tag | description | expected tag items |
[ | --- | --- | --- | --- | --- |
["p", "9ec7a778167afb1d30c4833de9322da0c08ba71a69e1911d5578d3144bb56437"], | Muted list | 30000 | `"mute"` | things the user doesn't want to see in their feeds | `"p"` (pubkeys), `"t"` (hashtags) |
["p", "8c0da4862130283ff9e67d889df264177a508974e2feb96de139804ea66d6168"] | Bookmarks list | 30001 | `"bookmark"` | things the user intends to save for the future | `"e"` (kind:1 notes), `"a"` (kind:30023 articles) |
] | Pin list | 30001 | `"pin"` | events the user intends to showcase in their profile page | `"e"` (kind:1 notes) |
``` | Relay sets | 30002 | (user-defined) | user-defined relay groups the user can easily pick and choose from during variadic operations | `"relay"` (relay URLs) |
Then the user would create a 'Mute' list event like below:
```json

## List Event Kinds
| kind | list type |
| ------ | ----------------------- |
| 10000 | Mute |
| 10001 | Pin |
| 30000 | Categorized People |
| 30001 | Categorized Bookmarks |
| 30002 | Categorized Relay Sets |
### Mute List
An event with kind `10000` is defined as a replaceable list event for listing content a user wants to mute. Any standardized tag can be included in a Mute List.
### Pin List
An event with kind `10001` is defined as a replaceable list event for listing content a user wants to pin. Any standardized tag can be included in a Pin List.
### Categorized People List
An event with kind `30000` is defined as a parameterized replaceable list event for categorizing people. The 'd' parameter for this event holds the category name of the list. The tags included in these lists MUST follow the format of kind 3 events as defined in [NIP-02 - Contact List and Petnames](02.md).
### Categorized Bookmarks List
An event of kind `30001` is defined as a parameterized replaceable list event for categorizing bookmarks. The 'd' parameter for this event holds the category name of the list. The bookmark lists may contain metadata tags such as 'title', 'image', 'summary' as defined in [NIP-23 - Long-form Content](23.md). Any standardized tag can be included in a Categorized Bookmark List.
### Categorized Relay Set
An event of kind `30002` is defined as a parameterized replaceable list event for categorizing relays. The 'd' parameter for this event holds the category name of the list. The relays lists may contain metadata tags such as 'title', 'image', 'summary' as defined in [NIP-23 - Long-form Content](23.md). These sets can be used by clients in order to determine which relays to query in different scenarios.
