 - The `<recommended relay URL>` item present on the `"e"` and `"p"` tags is an optional (could be set to `""`) URL of a relay the client could attempt to connect to fetch the tagged event or other events from a tagged profile. It MAY be ignored, but it exists to increase censorship resistance and make the spread of relay addresses more seamless across clients.
 - Clients should use the created_at field to judge the age of a metadata event and completely replace older metadata events with newer metadata events regardless of the order in which they arrive.  Clients should not merge any filled fields within older metadata events into empty fields of newer metadata events.

+Dealing with unknown event kinds
+--------------------------------
+
+`draft` `optional` `author:pablof7z` `author:fiatjaf`
+
+When creating a new custom event kind that is part of a custom protocol and isn't meant to be read as text (like `kind:1`), clients should use an `alt` tag to write a short human-readable plaintext summary of what that event is about.
+
+The intent is that social clients, used to display only `kind:1` notes, can still show something in case a custom event pops up in their timelines. The content of the `alt` tag should provide enough context for a user that doesn't know anything about this event kind to understand what it is.
+
+These clients that only know `kind:1` are not expected to ask relays for events of different kinds, but users could still reference these weird events on their notes, and without proper context these could be nonsensical notes. Having the fallback text makes that situation much better -- even if only for making the user aware that they should try to view that custom event elsewhere.
+
+`kind:1`-centric clients can make interacting with these event kinds more functional by supporting [NIP-89](https://github.com/nostr-protocol/nips/blob/master/89.md).

+Labeling
+---------
+
+`draft` `optional` `author:staab` `author:gruruya` `author:s3x-jay`
+
+A label is a `kind 1985` event that is used to label other entities. This supports a number of use cases, from distributed moderation and content recommendations to reviews and ratings.
+
+Label Target
+----
+
+The label event MUST include one or more tags representing the object or objects being
+labeled: `e`, `p`, `a`, `r`, or `t` tags. This allows for labeling of events, people, relays,
+or topics respectively. As with NIP-01, a relay hint SHOULD be included when using `e` and
+`p` tags.
+
+Label Tag
+----
+
+This NIP introduces a new tag `l` which denotes a label, and a new `L` tag which denotes a label namespace.
+A label MUST include a mark matching an `L` tag. `L` tags refer to a tag type within nostr, or a nomenclature
+external to nostr defined either formally or by convention. Any string can be a namespace, but publishers SHOULD
+ensure they are unambiguous by using a well-defined namespace (such as an ISO standard) or reverse domain name notation.
+
+Namespaces starting with `#` indicate that the label target should be associated with the label's value.
+This is a way of attaching standard nostr tags to events, pubkeys, relays, urls, etc.
+
+Some examples:
+
+- `["l", "footstr", "#t"]` - the publisher thinks the given entity should have the `footstr` topic applied.
+- `["l", "<pubkey>", "#p"]` - the publisher thinks the given entity is related to `<pubkey>`
+- `["l", "IT-MI", "ISO-3166-2"]` - Milano, Italy using ISO 3166-2.
+- `["l", "VI-hum", "com.example.ontology"]` - Violence toward a human being as defined by ontology.example.com.
+
+`L` tags containing the label namespaces MUST be included in order to support searching by
+namespace rather than by a specific tag. The special `ugc` ("user generated content") namespace
+MAY be used when the label content is provided by an end user.
+
+`l` and `L` tags MAY be added to other event kinds to support self-reporting. For events
+with a kind other than 1985, labels refer to the event itself.
+
+Label Annotations
+-----
+
+A label tag MAY include a 4th positional element detailing extra metadata about the label in question. This string
+should be a json-encoded object. Any key MAY be used, but the following are recommended:
+
+- `quality` may have a value of 0 to 1. This allows for an absolute, granular scale that can be represented in any way (5 stars, color scale, etc).
+- `confidence` may have a value of 0 to 1. This indicates the certainty which the author has about their rating.
+- `context` may be an array of urls (including NIP-21 urls) indicating other context that should be considered when interpreting labels.
+
+Content
+-------
+
+Labels should be short, meaningful strings. Longer discussions, such as for a review, or an
+explanation of why something was labeled the way it was, should go in the event's `content` field.
+
+Example events
+--------------
+
+A suggestion that multiple pubkeys be associated with the `permies` topic.
+
+```json
+{
+  "kind": 1985,
+  "tags": [
+    ["L", "#t"],
+    ["l", "permies", "#t"],
+    ["p", <pubkey1>, <relay_url>],
+    ["p", <pubkey2>, <relay_url>]
+  ],
+  "content": "",
+  ...
+}
+```
+
+A review of a relay.
+
+```json
+{
+  "kind": 1985,
+  "tags": [
+    ["L", "com.example.ontology"],
+    ["l", "relay/review", "com.example.ontology", "{\"quality\": 0.1}"],
+    ["r", <relay_url>]
+  ],
+  "content": "This relay is full of mean people.",
+  ...
+}
+```
+
+Publishers can self-label by adding `l` tags to their own non-1985 events.
+
+```json
+{
+  "kind": 1,
+  "tags": [
+    ["L", "com.example.ontology"],
+    ["l", "IL-frd", "com.example.ontology"]
+  ],
+  "content": "Send me 100 sats and I'll send you 200 back",
+  ...
+}
+```
+
+Other Notes
+-----------
+
+When using this NIP to bulk-label many targets at once, events may be deleted and a replacement
+may be published. We have opted not to use parameterizable/replaceable events for this due to the
+complexity in coming up with a standard `d` tag. In order to avoid ambiguity when querying,
+publishers SHOULD limit labeling events to a single namespace.
+
+Before creating a vocabulary, explore how your use case may have already been designed and
+imitate that design if possible. Reverse domain name notation is encouraged to avoid
+namespace clashes, but for the sake of interoperability all namespaces should be
+considered open for public use, and not proprietary. In other words, if there is a

+Methods for dealing with lost or compromised keys
+-------------------------------------------------
+
+`draft` `optional` `author:fiatjaf`
+
+This NIP defines a series of methods that can be used to make catastrophic key loss events less horrible.
+
+The intention here is not to claim that there is a generalized "key rotation" scheme on Nostr, but still make it
+so that in most cases people are able to move to new keys and not lost 100% of their followers and reputation
+when that happens, and also that it is possible to prevent most of the reputational damage that could be
+caused by having an evil hacker take control of someone else's keys.
+
+The implementation of this NIP could be done directly in social clients or in dedicated clients that users would
+visit from time to time in order to have an automated scan be done on their contacts and then the dedicated app
+could suggest migrating from old keys to new keys, or suggest stop following compromised keys, or even perform
+these migrations automatically.
+
+### Method A: Simple Key Deletion
+
+Based on https://github.com/nostr-protocol/nips/pull/377, the idea is that someone, after noticing that their key
+has been compromised and deciding that it is not possible to use any of the other methods here described, can
+proceed to publish the following event:
+
+```js
+{
+  "kind": 10529,
+  "pubkey": "<compromised-pubkey>",
+  "tags": [
+    ["reason", "I typed my key on anigma"]
+
+    // this is unnecessary, but it's an extra requirement to prevent people from making a 10529 event by chance
+    ["key-compromised"],
+  ],
+  "content": "",
+  // ...
+}
+```
+
+Upon receiving this, relays implementing this NIP SHOULD somehow mark it as invalid and refuse to store any more
+events from this key. Relays MAY also decide to also delete all events from this key.
+
+Upon receiving this, clients implementing this NIP SHOULD stop following the key.
+
+Clients may give users the option to "delete your public key" with this type of event. Clients SHOULD display a
+prominent message explaining that the action is not reversible, SHOULD explain that this does not guarantee their
+posts are deleted forever, and SHOULD require special confirmation such as requiring the user to type a message.
+
+### Method B: Social Key Migration
+
+The idea here is that users could pick some friends from their contact list and a threshold number to signal to
+the rest that the old key has been lost and what is the new key -- e.g. Alice can determine that, from Bob, Carol
+and Derek, if any 2 of these 3 agree, their recommendation is authoritative.
+
+This is done by publishing an event like this (for example):
+
+```js
+{
+  "kind": 10520,
+  "pubkey": "<user-pubkey-that-will-be-compromised>",
+  "tags": [
+    ["p", "<friend1-pubkey>"],
+    ["p", "<friend2-pubkey>"],
+    ["p", "<friend3-pubkey>"],
+    ["threshold", "2"]
+  ],
+  "content": "",
+  // ...
+}
+```
+
+And then, when the friends want to recommend the switch to a new pubkey, they can publish events like
+
+```js
+{
+  "kind": 1521,
+  "pubkey": "<friend1-pubkey>",
+  "tags": [
+    ["p", "<compromised-pubkey>"],
+    ["e", "<event-of-kind-10520-that-this-refers-to>"],
+    ["new-key", "<new-key>"]
+  ],
+  "content": "",
+  // ...
+}
+```
+
+Very importantly, when evaluating events of kind `1521` for a given `p`, clients should ensure that their corresponding
+event `10520` is at least 3 months older **and that an OpenTimestamps proof exists for that**.
+
+### Method C: Hierarchically Pregenerated Keys
+
+I'll write this later, just a placeholder. It's probably better to see if methods A and B work first.

 Having lightning receipts on nostr allows clients to display lightning payments from entities on the network. These can be used for fun or for spam deterrence.
 
 ## Protocol flow
 
 1. Client calculates a recipient's lnurl pay request url from the `zap` tag on the event being zapped (see Appendix G), or by decoding their lud06 or lud16 field on their profile according to the [lnurl specifications](https://github.com/lnurl/luds). The client MUST send a GET request to this url and parse the response. If `allowsNostr` exists and it is `true`, and if `nostrPubkey` exists and is a valid BIP 340 public key in hex, the client should associate this information with the user, along with the response's `callback`, `minSendable`, and `maxSendable` values.
-2. Clients may choose to display a lightning zap button on each post or on a user's profile. If the user's lnurl pay request endpoint supports nostr, the client SHOULD use this NIP to request a zap receipt rather than a normal lnurl invoice.

 3. When a user (the "sender") indicates they want to send a zap to another user (the "recipient"), the client should create a `zap request` event as described in Appendix A of this NIP and sign it.
 4. Instead of publishing the `zap request`, the `9734` event should instead be sent to the `callback` url received from the lnurl pay endpoint for the recipient using a GET request. See Appendix B for details and an example.
-5. The recipient's lnurl server will receive this request and validate it. See Appendix C for details on how to properly configure an lnurl server to support zaps, and Appendix D for details on how to validate the `nostr` query parameter.
-6. If the request is valid, the server should fetch a description hash invoice where the description is this note and this note only. No additional lnurl metadata is included in the description. This will be returned in the response according to [LUD06](https://github.com/lnurl/luds/blob/luds/06.md).

 8. Once the invoice is paid, the recipient's lnurl server MUST generate a `zap receipt` as described in Appendix E, and publish it to the `relays` specified in the `zap request`.

+Recommended Application Handlers
+--------------------------------
+
+`draft` `optional` `author:pablof7z`
+
+This NIP describes `kind:31989` and `kind:31990`: a way to discover applications that can handle unknown event-kinds.
+
+## Rationale
+Nostr's discoverability and transparent event interaction is one of its most interesting/novel mechanics.
+This NIP provides a simple way for clients to discover applications that handle events of a specific kind to ensure smooth cross-client and cross-kind interactions.
+
+### Parties involved
+There are three actors to this workflow:
+
+* application that handles a specific event kind (note that an application doesn't necessarily need to be a distinct entity and it could just be the same pubkey as user A)
+    * Publishes `kind:31990`, detailing how apps should redirect to it
+* user A, who recommends an app that handles a specific event kind
+    * Publishes `kind:31989`
+* user B, who seeks a recommendation for an app that handles a specific event kind
+    * Queries for `kind:31989` and, based on results, queries for `kind:31990`
+
+# Events
+
+## Recommendation event
+```json
+{
+    "kind": 31989,
+    "pubkey": <recommender-user-pubkey>,
+    "tags": [
+        [ "d", <supported-event-kind> ],
+        [ "a", "31990:app1-pubkey:<d-identifier>", "wss://relay1", "ios" ],
+        [ "a", "31990:app2-pubkey:<d-identifier>", "wss://relay2", "web" ]
+    ]
+}
+```
+
+The `d` tag in `kind:31989` is the supported event kind this event is recommending.
+
+Multiple `a` tags can appear on the same `kind:31989`.
+
+The second value of the tag SHOULD be a relay hint.
+The third value of the tag SHOULD be the platform where this recommendation might apply.
+
+## Handler information
+```json
+{
+    "kind": 31990,
+    "pubkey": <pubkey>,
+    "content": "<optional-kind:0-style-metadata>",
+    "tags": [
+        [ "d", <random-id> ],
+        [ "k", <supported-event-kind> ],
+        [ "web", "https://..../a/<bech32>", "nevent" ],
+        [ "web", "https://..../p/<bech32>", "nprofile" ],
+        [ "web", "https://..../e/<bech32>" ],
+        [ "ios", ".../<bech32>" ]
+    ]
+}
+```
+
+* `content` is an optional `set_metadata`-like stringified JSON object, as described in NIP-01. This content is useful when the pubkey creating the `kind:31990` is not an application. If `content` is empty, the `kind:0` of the pubkey should be used to display application information (e.g. name, picture, web, LUD16, etc.)
+
+* `k` tags' value is the event kind that is supported by this `kind:31990`.
+Using a `k` tag(s) (instead of having the kind onf the NIP-33 `d` tag) provides:
+    * Multiple `k` tags can exist in the same event if the application supports more than one event kind and their handler URLs are the same.
+    * The same pubkey can have multiple events with different apps that handle the same event kind.
+
+* `bech32` in a URL MUST be replaced by clients with the NIP-19-encoded entity that should be loaded by the application.
+
+Multiple tags might be registered by the app, following NIP-19 nomenclature as the second value of the array.
+
+A tag without a second value in the array SHOULD be considered a generic handler for any NIP-19 entity that is not handled by a different tag.
+
+# User flow
+A user A who uses a non-`kind:1`-centric nostr app could choose to announce/recommend a certain kind-handler application.
+
+When user B sees an unknown event kind, e.g. in a social-media centric nostr client, the client would allow user B to interact with the unknown-kind event (e.g. tapping on it).
+
+The client MIGHT query for the user's and the user's follows handler.
+
+# Example
+
+## User A recommends a `kind:31337`-handler
+User A might be a user of Zapstr, a `kind:31337`-centric client (tracks). Using Zapstr, user A publishes an event recommending Zapstr as a `kind:31337`-handler.
+
+```json
+{
+    "kind": 31989,
+    "tags": [
+        [ "d", "31337" ],
+        [ "a", "31990:1743058db7078661b94aaf4286429d97ee5257d14a86d6bfa54cb0482b876fb0:abcd", <relay-url>, "web" ]
+    ]
+}
+```
+
+## User B interacts with a `kind:31337`-handler
+User B might see in their timeline an event referring to a `kind:31337` event
+(e.g. a `kind:1` tagging a `kind:31337`).
+
+User B's client, not knowing how to handle a `kind:31337` might display the event
+using its `alt` tag (as described in NIP-31). When the user clicks on the event,
+the application queries for a handler for this `kind`:
+
+`["REQ", <id>, '[{ "kinds": [31989], "#d": ["31337"], 'authors': [<user>, <users-contact-list>] }]']`
+
+User B, who follows User A, sees that `kind:31989` event and fetches the `a`-tagged event for the app and handler information.
+
+User B's client sees the application's `kind:31990` which includes the information to redirect the user to the relevant URL with the desired entity replaced in the URL.
+
+## Alternative query bypassing `kind:31989`

-### Preamble
-
-Some [benchmarks](https://github.com/fiatjaf/nostr-json-benchmarks/tree/2f254fff91b3ad063ef9726bb4a3d25316cf12d8) made using all libraries available on Golang show that JSON decoding is very slow. And even when people do assembly-level optimizations things only improve up to a point (e.g. for decoding a Nostr event, the "Sonic" library uses about 50% of that of the standard library).
-
-Meanwhile, doing a simple TLV encoding reduces the decoding time to 35% and a simpler static binary format for Nostr events makes that number drop to 4%. However, it would be bad for Nostr if a binary encoding was introduced, as it would be likely to cause compatibility issues, centralize the protocol and/or increase the work for everybody, more about this in [this comment](https://github.com/nostr-protocol/nips/pull/512#issuecomment-1542368664).
-
-### The actual NIP
-
-NSON is a crazy idea that, according to the benchmarks above, reduces the decoding time to 14% of that of the standard library. It works by having the JSON sender encode the event _as JSON_, but in a specific, very strict, order of fields (taking advantage of the fact that Nostr events have static fields, static lengths for some fields, and an overall rigid structure) and include in the JSON object a new field called `"nson"` that contains metadata the JSON receiver can read to help in the decoding process.
-
-Here's an example of a NSON-encoded Nostr event:
-
-`{"id":"57ff66490a6a2af3992accc26ae95f3f60c6e5f84ed0ddf6f59c534d3920d3d2","pubkey":"79be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798","sig":"504d142aed7fa7e0f6dab5bcd7eed63963b0277a8e11bbcb03b94531beb4b95a12f1438668b02746bd5362161bc782068e6b71494060975414e793f9e19f57ea","created_at":1683762317,"nson":"2801000b0203000100400005040001004000000014","kind":1,"content":"hello world","tags":[["e","b6de44a9dd47d1c000f795ea0453046914f44ba7d5e369608b04867a575ea83e","reply"],["p","c26f7b252cea77a5b94f42b1a4771021be07d4df766407e47738605f7e3ab774","","wss://relay.damus.io"]]}`
-
-The idea is that `"id"` comes first, so it can be accessed by reading a slice of the string from character `7` to character `71`, `pubkey` from character `83` to `147` and so on. `"content"`, `"kind"` and `"tags"` have dynamic sizes, so their sizes are given by the values inside the `"nson"` field (which is also dynamic, its size given by its first byte).
-
-### Anatomy of the `"nson"` field
-
-It is hex-encoded. Some fields are a single byte, others are two bytes (4 characters), big-endian.
-
-                    tt: number of tags (let's say it's two)
-                      nn: number of items on the first tag (let's say it's 3)

-                                      1111: number of chars on the first item
-                                          2222: number of chars on the second item
-    "nson":"xxkkccccttnn111122223333nn11112222"
-            xx: nson size
-              kk: kind chars
-                cccc: content chars

-### Other restrictions
-
-Besides the field ordering and the presence of the `"nson"` field, other restrictions must be applied:
-
-- the `"created_at"` field must have 10, characters, which gives us a range of dates from about 20 years ago up to 250 years in the future.
-- to simplify decoding of `"content"` and `"tags"` strings, escape codes like `\uXXXX` are forbidden in NSON, UTF-8 must be used instead. `\n`, `\\` and `\"` are the only valid escaped sequences.
-
-### Backwards-compatibility
-
-Any reader who is not aware of the NSON-encoding can receive these events and decode them using whatever means they want. The `"nson"` field will just be ignored and life will continue as normal.
-
-Also, other event fields that may be present (for example, the NIP-03 `"ots"` field) can be added at the end, after `"tags"`, with no loss to anyone.
-
-### Other points worth mentioning
-
-- Relays can receive non-nsonified events from clients, then reformat and store them nsonified so they can serve future clients better by sending them NSON always.
-
-### Open questions to be edited out of the NIP
-
-- How to signal NSON support? I thought it would work to have an initial field `"n":1` (before `"id"`) on the JSON, which could be read very fast, but I don't know.

+HTTP Auth
+-------------------------
+
+`draft` `optional` `author:kieran` `author:melvincarvalho`
+
+This NIP defines an ephemerial event used to authorize requests to HTTP servers using nostr events.
+
+This is useful for HTTP services which are build for Nostr and deal with Nostr user accounts.
+
+## Nostr event
+
+A `kind 27235` (In reference to [RFC 7235](https://www.rfc-editor.org/rfc/rfc7235)) event is used.
+
+The `content` SHOULD be empty.
+
+The following tags are defined as REQUIRED.
+
+* `u` - absolute URL
+* `method` - HTTP Request Method
+
+Example event:
+```json
+{
+    "id": "fe964e758903360f28d8424d092da8494ed207cba823110be3a57dfe4b578734",
+    "pubkey": "63fe6318dc58583cfe16810f86dd09e18bfd76aabc24a0081ce2856f330504ed",
+    "content": "",
+    "kind": 27235,
+    "created_at": 1682327852,
+    "tags": [
+        [
+            "u",
+            "https://api.snort.social/api/v1/n5sp/list"
+        ],
+        [
+            "method",
+            "GET"
+        ]
+    ],
+    "sig": "5ed9d8ec958bc854f997bdc24ac337d005af372324747efe4a00e24f4c30437ff4dd8308684bed467d9d6be3e5a517bb43b1732cc7d33949a3aaf86705c22184"
+}
+```
+
+Servers MUST perform the following checks in order to validate the event:
+1. The `kind` MUST be `27235`.
+2. The `created_at` MUST be within a reasonable time window (suggestion 60 seconds).
+3. The `u` tag MUST be exactly the same as the absolute request URL (including query parameters).
+4. The `method` tag MUST be the same HTTP method used for the requested resource.
+
+When the request contains a body (as in POST/PUT/PATCH methods) clients SHOULD include a SHA256 hash of the request body in a `payload` tag as hex (`["payload", "<sha256-hex>"]`), servers MAY check this to validate that the requested payload is authorized.
+
+If one of the checks was to fail the server SHOULD respond with a 401 Unauthorized response code.
+
+All other checks which server MAY do are OPTIONAL, and implementation specific.
+
+## Request Flow
+
+Using the `Authorization` header, the `kind 27235` event MUST be `base64` encoded and use the Authorization scheme `Nostr`
+
+Example HTTP Authorization header:
+```
+Authorization: Nostr 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
