# Ditto custom events
Instead of using database tables, the Ditto server publishes Nostr events that describe its state. It then reads these events using Nostr filters.
## Ditto User (kind 30361)
The Ditto server publishes kind `30361` events to represent users. These events are parameterized replaceable events of kind `30361` where the `d` tag is a pubkey. These events are published by Ditto's internal admin keypair.
User events have the following tags:
- `d` - pubkey of the user.
- `name` - NIP-05 username granted to the user, without the domain.
- `role` - one of `admin` or `user`.
- `origin` - the origin of the user's NIP-05, at the time the event was published.
Example:
```json
{
"id": "d6ae2f320ae163612bf28080e7c6e55b228ee39bfa04ad50baab2e51022d4d59",

}
```
## NIP-78
[NIP-78](https://github.com/nostr-protocol/nips/blob/master/78.md) defines events of kind `30078` with a globally unique `d` tag. These events are queried by the `d` tag, which allows Ditto to store custom data on relays. Ditto uses reverse DNS names like `pub.ditto.<thing>` for `d` tags.
The sections below describe the `content` field. Some are encrypted and some are not, depending on whether the data should be public. Also, some events are user events, and some are admin events.
### `pub.ditto.pleroma.config`
NIP-04 encrypted JSON array of Pleroma ConfigDB objects. Pleroma admin API endpoints set this config, and Ditto reads from it.
