 # Quantum Safe Filesystem
 
+![](img/qsss_intro.png)  
+
 A redundant filesystem, can store PB's (millions of gigabytes) of information.
 
 Unique features:
 
-- Unlimited scalable (many petabytes) filesystem
+- Unlimited scalability (many petabytes)
 - Quantum Safe:
-  - On the TFGrid, no farmer knows what the data is about
-  - Even a quantum computer cannot decrypt
+  - On the TFGrid no farmer knows what the data is
+  - Even a quantum computer cannot decrypt the data
 - Data can't be lost
   - Protection for datarot, data will autorepair
 - Data is kept forever (data does not get deleted)
 - Data is dispersed over multiple sites
-- Sites can go down, data not lost
+  - Even if the sites go down the data will not be lost
 - Up to 10x more efficient than storing on classic storage cloud systems
-- Can be mounted as filesystem on any OS or any deployment system (OSX, Linux, Windows, Docker, Kubernetes, TFGrid, ...)
+- Can be mounted as filesystem on any OS or any deployment system (OSX, Linux, Windows, Docker, Kubernetes, TFGrid etc.)
 - Compatible with ± all data workloads (not high performance data driven workloads like a database)
 - Self-healing: when a node or disk is lost, the storage system can get back to the original redundancy level
-- Helps with compliance to regulations like GDPR (as the hosting facility has no view on what is stored, information is encrypted and incomplete)
-- Hybrid: can be installed onsite, public, private, ...

 This storage layer relies on 3 primitives of the ThreeFold technology : 
 
 - [0-db](https://github.com/threefoldtech/0-db) is the storage engine.
-It is an always append database, which stores objects in an immutable format. It allows keeping the history out-of-the-box, good performance on disk, low overhead, easy data structure and easy backup (linear copy and immutable files).

 - [0-stor-v2](https://github.com/threefoldtech/0-stor_v2) is used to disperse the data into chunks by performing 'forward-looking error-correcting code' (FLECC) on it and send the fragments to safe locations.
 It takes files in any format as input, encrypts the file with AES based on a user-defined key, then FLECC-encodes the file and spreads out the result
-to multiple 0-DBs. The number of generated chunks is configurable to make it more or less robust against data loss through unavailable fragments. Even if some 0-DBs are unreachable, you can still retrieve the original data, and missing 0-DBs can even be rebuilt to have full consistency. It's an essential element of the operational backup.

 - [0-db-fs](https://github.com/threefoldtech/0-db-fs) is the filesystem driver which uses 0-DB as a primary storage engine. It manages the storage of directories and metadata in a dedicated namespace and file payloads in another dedicated namespace.
