 ### Kinds
 
-Kinds specify how clients should interpret the meaning of each event and the other fields of each event (e.g. an `"r"` tag may have a meaning in an event of kind 1 and an entirely different meaning in an event of kind 10002). Each NIP may define the meaning of a set of kinds that weren't defined elsewhere. [NIP-10](10.md), for instance, specifies the `kind:1` text note for social media applications.

+## Interactive Rooms and Meetings
+-----
+
+`draft` `optional`
+
+Service providers want to offer Interactive Rooms to the Nostr network in such a way that participants can easily log and query by clients. This NIP describes a general framework to advertise rooms and their associated events.
+
+## Concepts
+
+### Interactive Room (kind:30312)
+
+A special event with `kind:30312` "Interactive Room" defines the configuration and properties of a virtual interactive space. Each room has a unique identifier and can host multiple events/meetings.
+
+```jsonc
+{
+  "kind": 30312,
+  "tags": [
+    ["d", "<unique identifier>"],              // Required: Room identifier
+    ["room", "<name of the room>"],            // Required: Display name
+    ["summary", "<description>"],              // Optional: Room description
+    ["image", "<preview image url>"],          // Optional: Room image
+    ["status", "<open, private, closed>"],     // Required: Room accessibility
+    ["service", "<url>"],                      // Required: URL to access the room
+    ["endpoint", "<url>"],                     // Optional: API endpoint for status/info
+    ["t", "<hashtag>"],                        // Optional: Multiple hashtags allowed
+    ["p", "<pubkey>", "<url>", "<role>", "<proof>"],  // Required: At least one provider
+    ["relays", "<url>", "<url>", /*...*/]     // Optional: Preferred relays
+  ],
+  "content": ""  // Usually empty, may contain additional metadata
+}
+```
+
+Room properties:
+* MUST be either open, private or closed. Closed means the room is not in operation.
+* MAY specify access control policy for private rooms (e.g. invite-only, payment required)
+* MAY persist when not in use
+* MUST have at least one provider with "Host" role
+* MAY have multiple providers with different roles
+Provider roles (p tags):
+* Host: Full room management capabilities
+* Moderator: Room moderation capabilities
+* Speaker: Allowed to present/speak
+* Optional proof field for role verification
+
+### Room Meeting (kind:30313)
+
+A special event with kind:30313 represents a scheduled or ongoing meeting within a room. It MUST reference its parent room using the d tag.
+
+```jsonc
+{
+  "kind": 30313,
+  "tags": [
+    ["d", "<event-unique-identifier>"],        // Required: Event identifier
+    ["a", "30312:<pubkey>:<room-id>", "wss://nostr.example.com"], // Required: Reference to parent room, 'd' from 30312
+    ["title", "<meeting-title>"],              // Required: Meeting title
+    ["summary", "<description>"],              // Optional: Meeting description
+    ["image", "<preview image url>"],          // Optional: Meeting image

+    ["total_participants", "<number>"],        // Optional: Total registered
+    ["current_participants", "<number>"],      // Optional: Currently active
+    ["p", "<pubkey>", "<url>", "<role>"],     // Optional: Participant with role
+  ],
+  "content": ""  // Usually empty, may contain additional metadata
+}
+```
+
+Event properties:
+* MUST reference parent room via d tag
+* MUST have a status (planned/live/ended)
+* MUST have a start time
+* MAY track participant counts
+* MAY include participant roles specific to the event
+Event management:
+* Clients SHOULD update event status regularly when live
+* Events without updates for 1 hour MAY be considered ended
+* starts and ends timestamps SHOULD be updated when status changes

+## Room Presence
+
+New `kind: 10312` provides an event which signals presence of a listener. 
+
+The presence event SHOULD be updated at regular intervals and clients SHOULD filter presence events older than 
+a given time window.
+
+**This kind `10312` is a regular replaceable event, as such presence can only be indicated in one room at a time.**

+```json

+
+## Top-level posts
+
+For top-level posts, the uppercase and lowercase NIP-22 tags should both refer to the community definition itself.

+
+## Backwards compatibility note
+
+Previously kind 1 events were used for posts in communities, with an "a" tag pointing to the community. For backwards compatibility, clients MAY still query for kind 1 events, but SHOULD NOT use them for new posts. Instead, clients SHOULD use kind 1111 events with the `A` and `a` tags as described above.
+

+Ecash Mint Discoverability
+--------------------------------
+
+`draft` `optional`
+
+This NIP describes `kind:38173`, `kind:38172` and `kind:38000`: a way to discover ecash mints, their capabilities, and people who recommend them.
+
+## Rationale
+
+Nostr's discoverability and transparent event interaction is one of its most interesting/novel mechanics.
+This NIP provides a simple way for users to discover ecash mints recommended by other users and to interact with them.
+
+### Parties involved
+
+There are three actors to this workflow:
+
+* An ecash mint operator, announces their mint and its capabilities.
+    * Publishes `kind:38173` or `kind:38172`, detailing how to connect to it and its capabilities.
+* user A, who recommends an ecash mint
+    * Publishes `kind:38000`
+* user B, who seeks a recommendation for an ecash mint
+    * Queries for `kind:38000` and, based on results, queries for `kind:38173`/`kind:38172`
+
+## Events
+
+### Recommendation event
+```json
+{
+  "kind": 38000,
+  "pubkey": <recommender-user-pubkey>,
+  "tags": [
+    ["k", "38173"],
+    ["d", "<d-identifier>"],
+    ["u", <recommended-fedimint-invite-code>],
+    ["a", "38173:fedimint-pubkey:<d-identifier>", "wss://relay1"]
+  ],
+  "content": "I trust this mint with my life"
+}
+```
+
+The recommendation event is a parameterized-replacable event so that a user can change edit their recommendation without creating a new event.
+
+The `d` tag in `kind:38000` is the `kind:38173`/`kind:38172` event identifier this event is recommending, if no event exists, the `d` tag can still be calculated from the mint's pubkey/id.
+The `k` tag is the kind number that corresponds to the event kind that the user is recommending, in this case `kind:38173` for fedimints and `kind:38172` for cashu mints.
+
+Optional `u` tags can be added to give a recommend way to connect to the mint.
+The value of the tag is the URL or invite code of the ecash mint.
+Multiple `u` tags can appear on the same `kind:38000`.
+
+`a` tags are used to point to the `kind:38173`/`kind:38172` event of the ecash mint.
+The first value of the tag is the `kind:38173`/`kind:38172` event identifier, the second value of the tag is a relay hint.
+This is used to correctly point to the mint's `kind:38173`/`kind:38172` event in case there are duplicates claiming to be the same mint.
+
+The content can be used to give a review.
+
+## Ecash Mint Information
+
+Cashu mints SHOULD publish `kind:38172` events to announce their capabilities and how to connect to them.
+
+For cashu mints, the `u` tag SHOULD be the URL to the cashu mint and it should list the nuts that the cashu mint supports.
+
+The `d` tag SHOULD be the mint's pubkey (found when querying `/v1/info`), this way users can query by pubkey and find the mint announcement.
+
+An `n` tag SHOULD be added to signify the network the cashu mint is on (either `mainnet`, `testnet`, `signet`, or `regtest`)
+
+```json
+{
+  "kind": 38172,
+  "pubkey": "<application-pubkey>",
+  "content": "<optional-kind:0-style-metadata>",
+  "tags": [
+    ["d", <cashu mint pubkey>],
+    ["u", "https://cashu.example.com"],
+    ["nuts", "1,2,3,4,5,6,7"],
+    ["n", "mainnet"]
+  ]
+}
+```
+
+Fedimints SHOULD publish `kind:38173` events to announce their capabilities and how to connect to them.
+
+For fedimints, it should list all known fedimint invite codes in `u` tags and it should list the modules it supports.
+
+The `d` tag SHOULD be the federation id, this way users can query by federation id and find the fedimint announcement.
+
+An `n` tag SHOULD be added to signify the network the fedimint is on (either `mainnet`, `testnet`, `signet`, or `regtest`)
+
+```json
+{
+  "kind": 38173,
+  "pubkey": "<application-pubkey>",
+  "content": "<optional-kind:0-style-metadata>",
+  "tags": [
+    ["d", <federation-id>],
+    ["u", "fed11abc.."],
+    ["u", "fed11xyz.."],
+    ["modules", "lightning,wallet,mint"],
+    ["n", "signet"]
+  ]
+}
+```
+
+* `content` is an optional `metadata`-like stringified JSON object, as described in NIP-01. This content is useful when the pubkey creating the `kind:38173` is not a normal user. If `content` is empty, the `kind:0` of the pubkey should be used to display mint information (e.g. name, picture, web, LUD16, etc.)
+
+## Example
+
+### User A recommends some mints
+User A might be a user of a cashu mint. Using a client, user A publishes an event recommending the cashu mint they use.
+
+```json
+{
+  "kind": 38000,
+  "tags": [
+    ["u", "fed11abc..", "fedimint"],
+    ["u", "https://cashu.example.com", "cashu"],
+    ["a", "38173:fedimint-pubkey:<d-identifier>", "wss://relay1", "fedimint"],
+    ["a", "38172:cashu-mint-pubkey:<d-identifier>", "wss://relay2", "cashu"]
+  ],
+  ...
+}
+```
+
+### User B finds a mint
+User B wants to use an ecash wallet, they need to find a mint.
+
+User B's wallet client queries for `kind:38000` events, looking for recommendations for ecash mints.
+
+```json
+["REQ", <id>, [{ "kinds": [38000], "authors": [<user>, <users-contact-list>], "#k": ["38173"] }]]
+```
+
+User B, who follows User A, sees that `kind:38000` event and tries to connect to the corresponding mints.
+
+### Alternative query bypassing `kind:38000`
+Alternatively, users might choose to query directly for `kind:38173` for an event kind. Clients SHOULD be careful doing this and use spam-prevention mechanisms or querying high-quality restricted relays to avoid directing users to malicious handlers.
+
+```json
+["REQ", <id>, [{ "kinds": [38173], "authors": [...] }]]
+```

 This NIP defines `kind:30402`: an addressable event to describe classified listings that list any arbitrary product, service, or other thing for sale or offer and includes enough structured metadata to make them useful.
 
-The category of classifieds includes a very broad range of physical goods, services, work opportunities, rentals, free giveaways, personals, etc. and is distinct from the more strictly structured marketplaces defined in [NIP-15](15.md) that often sell many units of specific products through very specific channels.
+The specification supports a broad range of use cases physical goods, services, work opportunities, rentals, free giveaways, personals, etc. To promote interoperability between clients implementing NIP-99 for e-commerce, you can find the extension proposal [here](https://github.com/GammaMarkets/market-spec/blob/main/spec.md) which standardizes the e-commerce use case while maintaining the specification's lightweight and flexible nature. While [NIP-15](15.md) provides a strictly structured marketplace specification, NIP-99 has emerged as a simpler and more flexible alternative.
 
 The structure of these events is very similar to [NIP-23](23.md) long-form content events.

+Voice Messages
+-----------
+
+**Status:** Draft
+
+This NIP defines new events `kind: 1222` for root messages and `kind: 1244` for reply messages to be used for short voice messages, typically up to 60 seconds in length.
+
+## Specification
+
+### Event Kind `1222` and Kind `1244`
+
+The `kind: 1222` event is defined as follows:
+
+-   `content`: MUST be a URL pointing directly to an audio file.
+    -   The audio file SHOULD be in `audio/mp4` (.m4a) format using AAC or Opus encoding. Clients MAY support other common audio formats like `audio/ogg`, `audio/webm`, or `audio/mpeg` (mp3), but `audio/mp4` is recommended for broad compatibility and efficiency.
+    -   The audio duration SHOULD be no longer than 60 seconds. Clients publishing `kind: 1222` events SHOULD enforce this limit or provide a clear warning to the user if exceeded.
+-   `tags`:
+    -   Tags MAY be included as per other NIPs (e.g., `t` for hashtags, `g` for geohash, etc.).
+
+  The `kind: 1244` event is defined as follows:
+  
+-    To be used for replies, `kind: 1244` events MUST follow the structure of `NIP-22`.
+-   `content`: MUST be a URL pointing directly to an audio file.
+    -   The audio file SHOULD be in `audio/mp4` (.m4a) format using AAC or Opus encoding. Clients MAY support other common audio formats like `audio/ogg`, `audio/webm`, or `audio/mpeg` (mp3), but `audio/mp4` is recommended for broad compatibility and efficiency.
+    -   The audio duration SHOULD be no longer than 60 seconds. Clients publishing `kind: 1222` events SHOULD enforce this limit or provide a clear warning to the user if exceeded.
+-   `tags`:
+    -   Tags MAY be included as per other NIPs (e.g., `t` for hashtags, `g` for geohash, etc.).
+
+
+## Visual representation with `imeta` (NIP-92) tag (optional)
+
+The following imeta (NIP-92) tags MAY be included so clients can render a visual preview without having to download the audio file first:
+
+- `waveform`: amplitude values over time, space separated full integers, less than 100 values should be enough to render a nice visual
+- `duration`: audio length in seconds
+

- a way to publish LLM prompts that describe modifications to software projects. Where code diffs usually expire in a couple of releases and require constant upkeep,tThese "prompt diffs" enable way longer-lasting, shareable software modifications.
-
-## Abstract
-
-A prompt diff is a Nostr event that contains instructions for an LLM to modify a codebase. Prompt diffs describe the intent and let LLMs handle the implementation details.

-# Implementation Guidelines
-### For Prompt Authors
-
-Write clear, specific prompts that describe intent rather than implementation
-Include context about why changes should be made in certain locations
-Specify what should NOT be changed to prevent over-modification
-Add test commands to verify the modification works
-Test prompts against the current main branch of the repository
-
-# Security Considerations
-
-* Always review LLM-generated changes before applying
-* Prompt Injection Protection: Clients MUST sanitize repository file contents before passing to LLMs to prevent malicious code comments or documentation from hijacking the modification intent
