+NIP-35
+======
+
+Torrents
+-----------
+
+`draft` `optional`
+
+This NIP defined a new `kind 2003` which is Torrent. 
+
+`kind 2003` is a simple torrent index where there is enough information to search for content and construct the magnet link. No torrent files exist on nostr.
+
+## Tags
+- `btih`: V1 BitTorrent Info Hash, as seen in the [magnet link](https://www.bittorrent.org/beps/bep_0053.html) `magnet:?xt=urn:btih:HASH`
+- `file`: A file entry inside the torrent, including the full path ie. `info/example.txt`
+
+In order to make torrents searchable by general category, you SHOULD include a few tags like `movie`, `tv`, `HD`, `UHD` etc.
+
+## Tag prefixes
+
+Tag prefixes are used to label the content with references, ie. `["t", "imdb:1234"]`
+
+- `tcat`: A comma separated text category path, ie. `["t", "tcat:video,movie,4k"]`, this should also match the `newznab` category in a best effort approach.
+- `newznab`: The category ID from [newznab](https://github.com/Prowlarr/Prowlarr/blob/develop/src/NzbDrone.Core/Indexers/NewznabStandardCategory.cs)
+- `tmdb`: [The movie database](https://www.themoviedb.org/) id.
+- `ttvdb`: [TV database](https://thetvdb.com/) id.
+- `imdb`: [IMDB](https://www.imdb.com/) id.
+- `mal`: [MyAnimeList](https://myanimelist.net/) id.
+- `anilist`: [AniList](https://anilist.co/) id.
+
+A second level prefix should be included where the database supports multiple media types.
+- `tmdb:movie:693134` maps to `themoviedb.org/movie/693134`
+- `ttvdb:movie:290272` maps to `thetvdb.com/movies/dune-part-two`
+- `mal:anime:9253` maps to `myanimelist.net/anime/9253`
+- `mal:manga:17517` maps to `myanimelist.net/manga/17517`
+
+In some cases the url mapping isnt direct, mapping the url in general is out of scope for this NIP, the section above is only a guide so that implementers have enough information to succsesfully map the url if they wish.

+```json
+{
+  "kind": 2003,›
+  "content": "<long-description-pre-formatted>",
+  "tags": [
+    ["title", "<torrent-title>"],
+    ["btih", "<bittorrent-info-hash>"],
+    ["file", "<file-name>", "<file-size-in-bytes>"],
+    ["file", "<file-name>", "<file-size-in-bytes>"],
+    ["t", "tcat:video,movie,4k"],
+    ["t", "newznab:2045"],
+    ["t", "imdb:tt15239678"],
+    ["t", "tmdb:movie:693134"],
+    ["t", "ttvdb:movie:290272"],
+    ["t", "movie"],
+    ["t", "4k"],
+  ]
+}
