+### Challenges
+
+Designing two separate apps can be a bit complicated. It would be easier for both app developers and users if all three modules (as shown in the image) were integrated into a single app. However, consolidating them into a single app might make it challenging for users to trust the app even if it's open source and lacks sufficient code reviewers.

 ## Security enhancement of an operating system (e.g. Linux OS)
 
 With technology like [AppImage](./appimage.md), there is no need to change the operating system. This further increases the security of the OS. One can also check if something has changed or tampered in the system files crucial for security by obtaining the hash of the OS folder, as it will have the same hash at all times. In the case of an OS update, the changed hash can be publicly declared.
