+Persona
+-------------------
+
+`draft` `optional`
+
+This NIP defines how to create personae for a user. A persona represents an account owned by the base account but serving a distinct purpose. It is not intended to function as a master-subkey system or a form of delegation. The relationship between the base account and the persona account is expressed using `kind 0` events with a few tags.
+
+## `kind 0` event
+
+### Base account
+
+```jsonc
+{
+  "kind": 0,
+  "tags": [
+    ["p", "<persona account pubkey>", "<optional description>"],
+  ],
+  // ...
+}
+```
+
+- The `p` tag contains a persona account pubkey. The optional description can be added.
+  - It MAY have multiple `p` tags.
+
+
+### Persona account
+
+```jsonc
+{
+  "kind": 0,
+  "tags": [
+    ["P", "<base account pubkey>"],
+  ],
+  // ...
+}
+```
+
+- The `P` tag contains the base account pubkey.
+  - It MUST NOT have multiple `P` tags.
