Week 41 2025 §

Replace bittorrent in status-go §

1. BlockExchange Performance and reliability

   • achieved:
     • Fixed DHT discovery eviction bug where nodes with perfect reliability (1.0) were prematurely removed from the routing table
     • Optimized block exchange engine with runtime quota-based yielding, achieving significant throughput improvements in both single-node and multi-node configurations
     • Comprehensive performance testing and validation across local, multi-node, and K8s environments establishing baseline metrics and identifying K8s-specific performance characteristics
   • next:
     • Test runtime quota optimizations in K8s environment and measure discovery ping RTT under load
     • Evaluate more aggressive runtime quota especially if discovery timeouts persist
     • Validate routing table stability during sustained large file transfers and multi-node concurrent workloads
     • Analyze K8s network and CPU performance characteristics (shared vs dedicated CPU) impacting both discovery timeouts and overall transfer performance
   • blockers:

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

   • achieved:
     • Completed the Go wrapper.
     • Improvements in nim-codex:
       • Distinguished between stop and close methods to manage node restarts properly.
       • Added configuration for block retry number.
     • Started working on a Go application integration example.
   • next:
     • Finish the Go example application.
     • Integrate the Go wrapper into Status Go.
   • blockers:

3. Integration with status-go

   • achieved
     • only a bit of testing
   • next:
     • testing + scheduled integration with the Codex lib
   • blockers:
     • Resource unavailable most of this week

4. NAT support

   • achieved
     • Initial AutoNAT integration finished
     • Started to reshuffle and trim down the original UPNP (and similar) support in nim-codex into the new NAT decision making component (ReachabilityManager).
     • Looking into how NAT traversal could be tested using Docker.
   • next:
     • Wrap up https://github.com/codex-storage/nim-codex/issues/1319, test it and submit PR
   • blockers:

Research future work §

1. Altruistic Mode.

• Continue research into existing solutions and recent publications related to privacy-first data storage/sharing.
• Document: Related work: Fileverse and BTFS
• Document: Related work: IPFS-FAN and Freenet Contracts
• Document: Use Case: Serving Dynamic Websites in Codex
• Implementation: Implemented batch FRI verifier prototype for the “trustless outsourcing of Reed-Solomon encoding” sub-project.
