@ -25,41 +25,59 @@ This NIP introduces a new tag: `delegation` which is formatted as follows:
##### Delegation Token
The **delegation token** should be a 64-bytes schnorr signature of the sha256 hash of the following string:
The **delegation token** should be a 64-byte Schnorr signature of the sha256 hash of the following string:
```
nostr:delegation:<pubkey of publisher (delegatee)>:<conditions query string>
```
For example, the token `c33c88ba78ec3c760e49db591ac5f7b129e3887c8af7729795e85a0588007e5ac89b46549232d8f918eefd73e726cb450135314bfda419c030d0b6affe401ec1` is signed by `86f0689bd48dcd19c67a19d994f938ee34f251d8c39976290955ff585f2db42e` and consists of:
```json
nostr:delegation:62903b1ff41559daf9ee98ef1ae67cc52f301bb5ce26d14baba3052f649c3f49:kind=1&created_at>1640995200
```
#### Example
Below is an example of an event published by `62903b1ff41559daf9ee98ef1ae67cc52f301bb5ce26d14baba3052f649c3f49`, on behalf of `86f0689bd48dcd19c67a19d994f938ee34f251d8c39976290955ff585f2db42e`.
```
# Delegator:
privkey: ee35e8bb71131c02c1d7e73231daa48e9953d329a4b701f7133c8f46dd21139c
pubkey: 8e0d3d3eb2881ec137a11debe736a9086715a8c8beeeda615780064d68bc25dd
# Delegatee:
privkey: 777e4f60b4aa87937e13acc84f7abcc3c93cc035cb4c1e9f7a9086dd78fffce1
pubkey: 477318cfb5427b9cfc66a9fa376150c1ddbc62115ae27cef72417eb959691396
```
Delegation string to grant note publishing authorization to the delegatee (477318cf) for the next 30 days.
```json
nostr:delegation:477318cfb5427b9cfc66a9fa376150c1ddbc62115ae27cef72417eb959691396:kind=1&created_at<1675721885
```
The delegator (8e0d3d3e) then signs the above delegation string, the result of which is the delegation token:
```
cbc49c65fe04a3181d72fb5a9f1c627e329d5f45d300a2dfed1c3e788b7834dad48a6d27d8e244af39c77381334ede97d4fd15abe80f35fda695fd9bd732aa1e
```
The delegatee (477318cf) can now construct an event on behalf of the delegator (8e0d3d3e). The delegatee then signs the event with its own private key and publishes.
```json

The event should be considered a valid delegation if the conditions are satisfied (`kind=1` and `created_at<1675721813` in this example) and, upon validation of the delegation token, are found to be unchanged from the conditions in the original delegation string.
Clients should display the delegated note as if it was published directly by the delegator (8e0d3d3e).
