+# Codex Archiving PoC FURPS
+
+## Functionality
+
+1. Any end user can publish a backup snapshot of the entire SDS log to Codex.
+2. End user (may be privileged) can publish the corresponding Codex CID with metadata over Waku to a dedicated snapshot content topic.
+3. Participants can query the Waku snapshot topic for the latest CID.
+4. Participants can retrieve the archived messages from Codex.
+5. Participants can perform a store Query for more recent messages following the snapshot timestamp and SDS state.
+
+## Usability
+
+1. Workflow should be conceptually identical, whether the Codex interaction is via a local node or Codex gateway.
+2. Publishing or retrieving via Codex should be optional.
+
+## Reliability
+
+## Performance
+
+
+## Supportability
+
+1. Developers can use this protocol in web applications.
