+# Standards Proposal Guide
+
+This document walks you through submitting standards proposals to standardize the BitTorrent Gateway's innovative streaming and hybrid protocol features.
+
+## 🎯 Overview
+
+The BitTorrent Gateway implements pioneering features that deserve standardization:
+
+1. **NIP-35 Streaming Extensions** - Adds streaming metadata to Nostr torrent announcements
+2. **Blossom BUD-09** - Streaming support for the Blossom protocol
+3. **Hybrid Protocol Specification** - BitTorrent + Blossom integration patterns
+
+## 📋 Required Pull Requests
+
+### 1. NIP-35 Streaming Extensions
+
+**Repository**: https://github.com/nostr-protocol/nips  
+**Target File**: `35.md`  
+**Type**: Enhancement to existing NIP  
+
+#### What to Propose
+
+Add streaming-specific tags to NIP-35 to support video/audio streaming announcements:
+
+**New Tags**:
+- `stream`: Direct streaming URL
+- `hls`: HLS playlist URL  
+- `duration`: Content duration in seconds
+- `video`: Resolution, framerate, codec info
+- `m`: MIME type (following NIP-94 convention)
+
+#### Proposed Addition to NIP-35
+
+```markdown
+## Streaming Extensions
+
+For content that supports streaming, the following additional tags MAY be included:
+
+- `stream` - Direct streaming URL for progressive download/streaming
+- `hls` - HLS playlist URL (.m3u8) for adaptive streaming  
+- `duration` - Duration in seconds for time-based media
+- `video` - Video metadata as `<resolution>`, `<framerate>`, `<codec>`
+- `m` - MIME type (following NIP-94)
+
+### Example with Streaming
+
+```json
+{
+  "kind": 2003,
+  "content": "High-quality nature documentary",
+  "tags": [
+    ["title", "Nature Documentary"],
+    ["x", "d1c5a0f85a4e4f3d8e7d8f9c6b5a4e3f2d1c0b9a8e7d6f5c4b3a2e1d0c9b8a7f6"],
+    ["file", "nature-doc.mp4", "2147483648"],
+    ["magnet", "magnet:?xt=urn:btih:..."],
+    ["webseed", "https://example.com/api/webseed/hash"],
+    ["stream", "https://example.com/api/stream/hash"],
+    ["hls", "https://example.com/api/stream/hash/playlist.m3u8"],
+    ["duration", "3600"],
+    ["video", "1920x1080", "30fps", "h264"],
+    ["m", "video/mp4"],
+    ["t", "video"],
+    ["t", "streaming"],
+    ["tcat", "video,documentary"]
+  ]
+}
+```
+
+These extensions enable:
+- **Stream Discovery**: Users can find streamable content
+- **Player Integration**: Video players can directly consume streams  
+- **Quality Selection**: Multiple formats and qualities can be announced
+- **Social Streaming**: Comments and reactions on streaming content
+```
+
+### 2. Blossom BUD-11: Streaming Support
+
+**Repository**: https://github.com/hzrd149/blossom  
+**Target Directory**: `buds/`  
+**File**: `buds/11.md`  
+**Type**: New BUD (Blossom Upgrade Document)
+
+#### What to Propose
+
+Create BUD-11 to define streaming endpoints and behavior for Blossom servers:
+
+**New Endpoints**:
+- `GET /{hash}/stream` - Direct blob streaming with range support
+- `GET /{hash}/playlist.m3u8` - HLS playlist generation  
+- `GET /{hash}/segment/{n}` - HLS segment delivery
+- `GET /{hash}/info` - Media metadata extraction
+
+#### Complete BUD-11 Draft
+
+```markdown
+# BUD-11: Streaming Support
+
+## Abstract
+
+This BUD defines streaming endpoints for Blossom servers to support direct video/audio streaming and HLS (HTTP Live Streaming) delivery from stored blobs.
+
+## Motivation  
+
+As Blossom adoption grows for media storage, there's increasing need for streaming capability without requiring separate streaming infrastructure. This BUD enables:
+
+- Direct blob streaming with HTTP range support
+- HLS playlist generation from single blobs  
+- Adaptive streaming for better user experience
+- Integration with existing video players
+
+## Specification
+
+### Streaming Endpoint
+
+```
+GET /<hash>/stream
+```
+
+Servers implementing BUD-09 MUST support:
+- HTTP range requests (RFC 7233)  
+- Proper MIME type detection and headers
+- CORS headers for web player compatibility
+
+**Headers**:
+- `Accept-Ranges: bytes`
+- `Content-Type: <detected-mime-type>`
+- `Content-Length: <blob-size>`
+- `Access-Control-Allow-Origin: *`
+
+### HLS Playlist Endpoint  
+
+```
+GET /<hash>/playlist.m3u8
+```
+
+For video/audio blobs, servers MAY generate HLS playlists:
+- Virtual segmentation of the blob
+- Standard M3U8 format compliance
+- Segment duration typically 6-10 seconds
+
+**Example Response**:
+```
+#EXTM3U
+#EXT-X-VERSION:3
+#EXT-X-TARGETDURATION:7
+#EXT-X-MEDIA-SEQUENCE:0
+#EXT-X-PLAYLIST-TYPE:VOD
+#EXTINF:6.000,
+<hash>/segment/0
+#EXTINF:6.000,
+<hash>/segment/1
+#EXT-X-ENDLIST
+```
+
+### HLS Segment Endpoint
+
+```  
+GET /<hash>/segment/<n>
+```
+
+Delivers virtual segments from the blob:
+- Segment boundaries calculated from blob size
+- Proper byte range extraction  
+- Video container format preservation
+
+### Media Info Endpoint
+
+```
+GET /<hash>/info  
+```
+
+Returns JSON metadata about media blobs:
+
+```json
+{
+  "hash": "sha256...",
+  "size": 104857600,
+  "mime_type": "video/mp4", 
+  "duration": 3600,
+  "video": {
+    "width": 1920,
+    "height": 1080,
+    "codec": "h264",
+    "fps": "30"
+  },
+  "streaming": {
+    "stream_url": "/<hash>/stream",
+    "hls_url": "/<hash>/playlist.m3u8"
+  }
+}
+```
+
+## Implementation Notes
+
+- Servers SHOULD cache generated playlists for performance
+- Range requests MUST be handled efficiently for large blobs
+- Video codec compatibility varies by browser
+- Consider implementing quality variants for adaptive streaming
+
+## References
+
+- RFC 8216: HTTP Live Streaming (HLS)
+- RFC 7233: Range Requests  
+- BUD-01: Authorization  
+- BUD-02: Upload and List
+```
+
+### 3. Hybrid Protocol Specification
+
+**Repository**: Create new repository or add to existing project  
+**Target**: New specification document  
+**Type**: Protocol definition
+
+#### What to Propose
+
+Document the hybrid BitTorrent + Blossom approach as a reusable pattern:
+
+**Key Components**:
+- Storage threshold rules (when to use Blossom vs BitTorrent)
+- WebSeed integration patterns
+- Chunk mapping strategies  
+- Fallback hierarchies
+- P2P bootstrapping methods

+### Step 5: Submit Pull Requests
+
+#### NIP-35 Pull Request
+
+```bash
+cd nips
+git push origin nip-35-streaming-extensions
+```
+
+**PR Title**: `NIP-35: Add streaming extensions for video/audio content`
+
+**PR Description**:
+```markdown
+## Summary
+
+This PR extends NIP-35 to support streaming media by adding optional tags for direct streaming and HLS delivery.
+
+## Motivation
+
+Current NIP-35 only supports basic torrent metadata. With the growth of video/audio content on Nostr, there's a need for streaming-specific metadata that enables:
+
+- Direct video streaming in clients
+- HLS playlist discovery  
+- Media player integration
+- Social features around streaming content
+
+## Changes
+
+- Added `stream` tag for direct streaming URLs
+- Added `hls` tag for HLS playlist URLs
+- Added `duration` tag for time-based media
+- Added `video` tag for resolution/codec metadata
+- Added `m` tag for MIME type (consistent with NIP-94)
+- Updated example to demonstrate streaming extensions
+
+## Implementation
+
+This extension is already implemented in the BitTorrent Gateway project:
+https://github.com/YOUR_USERNAME/torrentGateway
+
+## Backward Compatibility
+
+All new tags are optional. Existing NIP-35 implementations continue to work unchanged.
+```
+
+#### BUD-11 Pull Request  
+
+```bash
+cd blossom
+git push origin bud-11-streaming-support
+```
+
+**PR Title**: `BUD-11: Add streaming support for media blobs`
+
+**PR Description**:
+```markdown  
+## Summary
+
+This BUD defines streaming endpoints that enable Blossom servers to serve video/audio content directly with support for HTTP range requests and HLS streaming.
+
+## Motivation
+
+Blossom is increasingly used for media storage, but lacks streaming capability. This BUD enables:
+
+- Direct blob streaming without separate infrastructure
+- HLS support for adaptive streaming
+- Better user experience for video/audio content  
+- Integration with standard video players
+
+## Specification
+
+- `GET /<hash>/stream` - Direct streaming with range support
+- `GET /<hash>/playlist.m3u8` - HLS playlist generation
+- `GET /<hash>/segment/<n>` - HLS segment delivery  
+- `GET /<hash>/info` - Media metadata endpoint
+
+## Implementation
+
+Reference implementation available in:
+https://github.com/YOUR_USERNAME/torrentGateway
+
+The implementation demonstrates practical usage and performance characteristics.
+```
+
+### Step 6: Follow Up and Iterate
+
+1. **Respond to Feedback**: Address reviewer comments promptly
+2. **Update Implementation**: Make changes based on specification feedback
+3. **Community Engagement**: Participate in discussions and decisions
+4. **Documentation**: Update your implementation as specs evolve
