# NIP-1078

## Arbitrary custom app data

`draft` `optional` `author:BlowaterNostr`

## Nostr event
|
|
|
|
This NIP specifies the use of event kind `1078` which is almost identical to 30078 except that it's not a replacible event.
|
|
|
|
## Some use cases
|
|
The reason to not having a 30078 is that some clients want to implement local state changes as CRDTs, meaning support cumulative and associative mutations.
|
|
|
|
Meaning the order of applying operations doesn't change the final result as long as the same set of operations are applied.
|
|
|
|
For example, in [Blowater](https://blowater.deno.dev), Pin/Unpin Contacts is implemented as regular events to achieve better consistency.
|
|
|
|
Event set [`Pin Npub X`, `Unpin NpubX`, `Pin Npub Y`] will result in a pin list of `[Y]` no matter how the order is shifted.
|
|
|
|
Many other operations are best implemented as CRDTs as well.
