Codex is currently in its first proof of concept iteration, codenamed Dagger. Before Katana—the name of the forthcoming beta main net release, expected by the end of 2023—we aim to deliver two additional PoC clients, Scimitar and Longsword
- **Scimitar:** The PoC-2 client will implement fast erasure coding, the marketplace and partial durability guarantees—expected end of Q3 2023.
- **Longsword:** Codex PoC-3 will improve on the SNARK-based remote auditing mechanism and add bandwidth incentives to the marketplace—expected end of Q3 2023.
- **Katana:** Codex v1 brings payment channels to the network, adds the bandwidth-preserving lazy repair scheme and makes further improvements to durability guarantees.
We believe the above roadmap to be the most logical approach to building a data storage engine with stronger durability guarantees and resistance to censorship than currently offered by Codex's centralized or decentralized counterparts while providing incredibly strong resistance to censorship.
First, we must establish a mechanism through which users can initiate a contract with a storage provider to host their data. Then, we can add erasure coding, required for efficient redundancy and auditing. Next, the system needs a way to prove the hosts still have data available. Finally, repairs must be incentivized. Naturally, each layer of sophistication requires testing for economic and technical feasibility.
