My 2024 review and high-level report. Let's start with some stats for the nostr.build:

- 720 Million media requests served

- 650 TiB of bandwidth consumed

- 8 Million unique visitors

- 85% average cache hit rate

- Improved median CPU time per request from 200 down to 2 milliseconds per request

- 20 requests per second are served on average

- 99.994% uptime for the hosted media

- 98% uptime for the website and uploading servers

- 2.5K daily free uploads on average

Some improvements for the free uploads:

- Increased free upload size from 10MiB to 50MiB

- Increased image resolution from 1980px to 3840px

- Increased per server RAM from 1GiB to 4GiB

- Added full mirror of all uploaded media to the additional vendor (backup)

- Implemented moderation headers (can be used to hide NSFW content if desired)

Now some of the stats of my dev work for the nostr.build:

- 1,333 git commits

- 42 repositories with my contributions

- 10k+ lines of code written, or changed

Some features and completed projects:

- Rewritten nostr.build account page (AI, stats, nostr share, drag-n-drop, variaty of sizes, poster for video, etc.)

- Added AI Studio, onboarded multiple models from SD and Flux.

- Added media statistics

- Rewritten media serving front-end (dropping CPU utilization by 100x) and improving TTFB as well as cache hit rate (from 50%+ to 85%+ on average)

- Implemented variaty of the spam, and other illegal media upload prevention mechanisms (automated AI media scanner, PhotoDNA scanner, etc.)

- Implemented AI Moderation API that is shareable with other nostr media hosts (e.g., nostrcheck.me)

- Implemented upload of pdf, zip, etc., with full virus scanning.

- Various improvements to the PHP code, bug fixes and optimizations.

- Implemented e.nostr.build to allow easy embedding and sharing of the video/audio files for the account holders

- Referal links and account credits

- Onboarded more nostr clients for uploads (e.g., YakiHonne)

Some of the prototyping I've done for nostr.build:

- Semantic search of the media (ML based), multilingual

- Basic search for media using AI Vision

- Video transcoding using serverless and server-based setups

- Video transcoding to DASH/HLS (CMAF)

- Multi-party audio/video chat

Some of the in-flight projects that I'll have to complete in 2025:

- Seamless implementation of the Blossom protocol (70% done)

- Rewrite of the post-upload scanning to utilize workflows (50% done)

- New video upload and transcoding experience, HLS, DASH, VBR video/audio (10% done)

- New NoSQL based data-plane backend with the new API (50% done)

- Full rewrite of the Accounts page (5% done, blocked by new API and data-plane)

- Additional models for the AI Studio (90% done)

- (25% done)

I am sure I am forgetting a bunch, and this is only done from my memory.
