# Backend Report 1 

 **STORAGE**
 Phala allows team to opt in either for centralized or decentralized storage using offchain queries. In Ordum we are exploring for both of them as we analyse pros and cons. For centralized databases we are currently exploring **Firestore** and **Mongo Db**.
 Centralized storage candidate is Crust. Things which will be stored will be but not limited to Completion Certificates, User applications and Miscellenius data.

*Challenges for storage*
* We do care about ownership of user data as to why we are thinking of decentralized databes but the bottleneck is for us to deliver within the time and to test the product to the user we are much better to use centralized databases.
* Long term aim is to have data portability as the Certificates acquired should and must be controlled by their owners.

 **ORDUM-CLI and contracts**
 We aim to build a simple command-line application for terminal lovers, as this will enable teams to view and apply relevant grants without living the workspace (i.e terminal). 
 
 *Challenges faced while building*
 * Subxt doesnt work well with Phat contract
 * Sumbitting Phat queries (offchain functions for phala) from the client is still cumbersome as lack of proper documentation
 
 *What did we get done at the moment*
 * Phat contract with creation and managing of user  profiles
 * Application functionality for grants
 
 *What is remaining for the POC*
 * Listing grants and their application processes.
 * Kusama treasury grant simplified application

**SUBSQUID**
We aim to use subquid chain indexers for the phat contract's front end.

- Do we have anything to list for FrontEnd?
