 # Ironforce + Degeon
 IronForce is a peer-to-peer decentralized network, Degeon is a messenger built on it.
 In this repository there is three Cargo crates and one python project:
 - `ironforce` is the decentralized network
 - `degeon_core` contains messenger's protocol
 - `degeon` is the messenger app in Rust + Iced
 - `degeon_py` is a version of the messenger app in Python + Pygame
 ![](images/dependency_graph.png)
 # Ironforce
-The Ironforce network:
+IronForce is a decentralized network
 - Has messages encrypted and signed using RSA
 - Can build efficient tunnels between two nodes
 - Is anonymous: it's very hard to create a connection between a node's IP and its public key
 - Can be extended to support any interface, like Bluetooth or even radio
 - Can run on ARM microcontrollers
 ![](images/scheme.png)
 ### Running IronForce
 The `IF` network has a worker daemon that can be used to read the broadcast messages and write them.
 Also, you can us `IF` as a Rust library (as it's done in Degeon).
 To get started:
 1. Clone this repository: `git clone ssh://git@gitlab.ennucore.com:10022/ironforce/ironforce.git`
 2. Install Rust and Cargo. The best way to do this is to use RustUp:
 ```shell
 sudo pacman -S rustup    # this is for Arch Linux, on other distros use the corresponding package manager
 rustup default nightly   # this will install rust & cargo (nightly toolchain)
 ```
 3. Run the worker:
 ```shell
 cd ironforce/ironforce
 cargo build --features std    # This will build ironforce network
 # To run the worker, use this:
 cargo run --bin worker --features std
 ```
 # Degeon
 Degeon is a messenger built on IronForce to show its abilities.
 Its core is in the crate `degeon_core`. The crate can be used as a Python module or in Rust.
 To build it, install Cargo and Rust, then do this:
 ```shell
 cd ironforce/degeon_core
 cargo build
 ```
 You will find the `libdegeon_core.so` file that can be used in Python in the `target/debug` directory.
 It should be renamed to `degeon_core.so`. 
 In Windows Rust should generate a `.dll` file that you will be able to use likewise.
 There are two GUI options for this interface:
 - A Rust + Iced client (preferred)
 - A Pygame client
 To run the Rust client, `cd` into the `degeon` folder of this repository, then use cargo:
 `cargo run`. 
 Note: this application requires Vulkan to be installed. 
 For me on Arch Linux and Intel GPU the installation command was `sudo pacman -S vulkan-intel`.
 On most systems it should be pre-installed.
