## Week 40 2025

### [Replace bittorrent in status-go](https://github.com/codex-storage/nim-codex/milestone/8)

1. [BlockExchange Performance and reliability](https://github.com/codex-storage/nim-codex/issues/974)
- **achieved**:
- Resolved peer discovery failure mode where refresh state remained locked after non-responsive peers
- Implemented weighted random peer selection favoring less-loaded and more reliable peers for proportional load distribution
- Validated system behavior under distributed workload using local Kubernetes cluster deployment
- **next**:
- Evaluate peer selection heuristics incorporating reliability metrics beyond load
- Analyze load distribution characteristics under sustained concurrent file transfer on Kubernetes cluster
- **blockers**:

4. [Implement a Codex library so that clients can use Codex directly from their apps](https://github.com/codex-storage/nim-codex/issues/1220)
- **achieved:**
- Completed the download feature by adding `fetchManifest`.
- Implemented the remaining Data API features: network download, block/dataset deletion, manifest listing, and node space retrieval.
- Fixed memory and pointer issues.
- Began extracting the Go wrapper into a separate GitHub repository for easier integration (with tests and documentation).
- **next:**
- Finalize the Go wrapper repository.
- Create an example project that demonstrates usage of the Go
- **blockers:**

5. [Integration with status-go](https://github.com/codex-storage/nim-codex/issues/1304)
- **achieved**
- first raw draft of complete integration:
- community owner: sharing history archives with both BitTorrent and Codex
- community member: can choose from three modes of operations when downloading the the archives:
- auto - the first comming, satisfying (in term of recency) archive index dicatates which channel (BT or Codex) will be used for fetching individual archives.
- codex - BitTorrent archive index ignored
- torrent - Codex archive index CID ignored
- **next:**
- testing/fixing bugs and fine-tuning the design to make sure nothing is missing
- documenting
- **blockers:**

6. [NAT support](https://github.com/codex-storage/nim-codex/issues/904)
- [Extensions of Multiformats in nim-libp2p](https://github.com/vacp2p/nim-libp2p/issues/1682): PR opened https://github.com/vacp2p/nim-libp2p/pull/1734
- Researched how `nwaku` utilizes both libp2p NAT traversal and UPnP.
- [Started implementation of the NAT and reachability detection using AutoNAT](https://github.com/codex-storage/nim-codex/issues/1319).

### [Research future work](https://github.com/codex-storage/nim-codex/milestone/9)

1. **Altruistic Mode.**
* Wrapped up our understanding of [Swarm incentives](https://hackmd.io/aSkvCy-LT8GjjdOzTrrLfw);
* Ongoing research into existing solutions and recent publications related to privacy-first data storage/sharing as we rebuild our knowledge of related approaches.
* **Document:** [Related work on privacy-first decentralized data storage/sharing](https://hackmd.io/ezscQOlBSsWXQhTQxSgbVA)
* **Document:** Summary of [research findings](https://hackmd.io/4iFskVZwRoSediZePbnj6A) into approaches for lightweight storage proofs with outsourcing erasure coding.
* **Implementation:** About 85% of the first prototype of the "outsourcing Reed-Solomon encoding" sub-project is implemented [here](https://github.com/codex-storage/outsourcing-Reed-Solomon)
