Protonet
A Cross-Platform, Multi-Communication, Serverless (Decentralized) App.
Important
This version is a complete rewrite from scratch and currently intended for the Polygon Hackathon on Devpost There's much improvement from the previous implementation. The previous version can be found here.
About
Protonet is a communication app, based on modern techniques, intended to be a secure way of interaction, whether Text Messaging or Voice Calling or Video Sharing or Purchasing Crypto Currencies or Using Crypto Currencies for shopping, should be reliable and secure. It is based upon blockchain compatible wallet. It allows a blockchain user to communicate with another blockchain user, independent of what blockchain they belong. It also allows auto creation of blockchain wallet account.
Security
Security is the primary concern of this app and hence it takes it seriously. A user password is required to access the app. The app doesn't save the user password anywhere. The user can then either copy/paste private key from clipboard or auto create a new account. The private key is encrypted with user's password and then stored in the database. This makes sure that the original private key is never stored on the user's device and if for any reason(s), the app's database base is compromised, then the attacker will need your password to view private key(s).
Security Notes
The app is in very early stage(alpha) and not recommended for production. If the user looses his password then there's no way he can access the account(s) in this app. The app clears the clipboard after private key is pasted for better security. There are some OS like Windows 10 where clipboard history can be maintained and enabled. If that's the case (or similar) with your OS, then make sure it is disabled, otherwise your private key is vulnerable to attackers, especially in copy/paste private key process.

Prerequisites
Running
From commandline/terminal, cd into the root directory of this project, then make sure all the dependencies are
installed. Run go get ./..., followed by go run .
Android Build
Make sure AndroidStudio and AndroidSdk is installed
Run the following command inside the root directory of the project from terminal/commandline
gogio -x -buildmode archive -appid protonet.x -o ./android/app/libs/protonet.aar -version 1 -target android .
The above command will generate protonet.aar file inside android/app/libs directory.
Now open the android folder using Android Studio IDE
The IDE will help you out with the rest of the debug/run/build process.
