Week 42 2025 §

Replace bittorrent in status-go §

1. BlockExchange Performance and reliability

   • achieved:
     • Implemented comprehensive memory diagnostics including GC statistics logging, pending blocks tracking, and libp2p connection tracking to compare local vs K8s behavior
     • Added connection cleanup on stream failures
   • next:
     • Commit Vector configuration files for Codex benchmarks
     • Scale testing in K8s - Test larger files (>10GB) and higher node counts (>32 nodes) to validate memory behavior and performance characteristics
   • blockers:

2. Implement a Codex library so that clients can use Codex directly from their apps

   • achieved:
     • Completed the Go example application: https://github.com/codex-storage/example-codex-go-bindings
     • Set up GitHub CD to publish Codex library files, allowing quick integration into any project (via download and environment variables)
   • next:
     • Use the library in the current Status Go integration
   • blockers:
     • Waiting for the Status Go integration code to move forward before using the library

3. Integration with status-go

   • achieved:
     • finished (draft) of the archive download flow - most importantly importing archives after they are downloaded
     • parallelizing the archive download (initial implementation was sequential)
     • tested the low-level CodexClient abstraction (appears to do what it is supposed to do)
   • next:
     • a small isolated utility project around CodexClient, so that it is easier to test codex-lib integration in isolation (almost finished)
     • testing the layers above the CodexClient:
       • downloading of the history index (codex_index_downloader.go)
       • downloading of the history archives (codex_archive_downloader.go)
   • blockers:

4. NAT support

   • achieved:
     • small advance in upnp component refactor
   • next:
   • blockers:

Research future work §

1. Altruistic Mode.

• Document: Research into Tor & Tribler and a summary of how they work and the anonymity guarantees that they provide, which Codex can utilize in the new design.

2. Roadmap.

• Document: Tentative short-term roadmap and FURPS
• Document: Tentative longer-term roadmap
