NIP-Metadata

Metadata events

draft optional

Defines a protocol for metadata events. Metadata events hold metadata information about other events, or entities

Kind 34578 — Metadata Event

Metadata events use kind 34578 (addressable). They are distinguished by their d tag and the presence of the ["t", "<sub_type>"] tag. The content of a metadata event always has a json which is encrypted to the author's pubkey. The shape of the json depends on the sub type of the metadata event

Examples

User metadata event:

{
  "kind": 34578,
  "pubkey": "abc123...",
  "created_at": 1700000000,
  "tags": [
    ["d", "0:abc123..."],
  ],
  "content": "<nip44-ciphertext of json encrypted to abc123>",
  "sig": "..."
}
