/*

The big Question is , Are you woke ?

Are you woke to what is happening right now in the world?

Governments are not our allies; we are starting a movement to escape that.
Resist the governments.

Private encrypted messaging service powered by blockchain technology coming soon.
 
Along with decentralised hosting services.

A place or platform where your messages are really end-to-end encrypted and not fake encryption like other platforms which leaks your data to the government.

First true decentralised messaging platform is coming 🔜.
