## The Nym Privacy Platform

The platform is composed of multiple Rust crates. Top-level executable binary crates include:

* `nym-node` - a tool for running a node within the Nym network. Nym Nodes containing functionality such as `mixnode`, `entry-gateway` and `exit-gateway` are fundamental components of Nym Mixnet architecture. Nym Nodes are ran by decentralised node operators. Read more about `nym-node` in [Operators Guide documentation](https://nymtech.net/operators/nodes/nym-node.html). Network functionality of `nym-node` (labeled with `--mode` flag) can be:
	- `mixnode` - shuffles [Sphinx](https://github.com/nymtech/sphinx) packets together to provide privacy against network-level attackers.
	- `gateway` - acts sort of like a mailbox for mixnet messages, which removes the need for direct delivery to potentially offline or firewalled devices. Gateways can be further categorized as `entry-gateway` and `exit-gateway`. The latter has an extra embedded IP packet router and Network requester to route data to the internet.
* `nym-client` - an executable which you can build into your own applications. Use it for interacting with Nym nodes.
* `nym-socks5-client` - a Socks5 proxy you can run on your machine and use with existing applications.
* `nym-explorer` - a (projected) block explorer and (existing) mixnet viewer.
* `nym-wallet` - a desktop wallet implemented using the [Tauri](https://tauri.app)) framework.
* `nym-cli` - a tool for interacting with the network from the CLI.
<!-- coming soon
* `nym-network-monitor` - sends packets through the full system to check that they are working as expected, and stores node uptime histories as the basis of a rewards system ("mixmining" or "proof-of-mixing").

### Building

* Platform build instructions are available on Nym [Operators Guide documentation](https://nymtech.net/operators/binaries/building-nym.html).
* Wallet build instructions are available [here](https://github.com/nymtech/nym/tree/master/nym-wallet#installation-prerequisites---linux--mac).

### Developing

References for developers:

* [Dev Docs](https://nym.com/docs/developers)
* [SDKs](https://nym.com/docs/developers/rust)
* [Network Docs](https://nym.com/docs/network)
* [Release Cycle - git flow](https://nym.com/docs/operators/release-cycle)

### Developer chat

You can chat to us in the #dev channel on [Matrix](https://matrix.to/#/#dev:nymtech.chat) or on the [Nym Forum](https://forum.nymtech.net).

### Tokenomics & Rewards

Nym network economic incentives, operator and validator rewards, and scalability of the network are determined according to the principles laid out in the section 6 of [Nym Whitepaper](https://nymtech.net/nym-whitepaper.pdf).
Initial reward pool is set to 250 million Nym, making the circulating supply 750 million Nym.

### Licensing and copyright information

This is a monorepo and components that make up Nym as a system are licensed individually, so for accurate information, please check individual files.

As a general approach, licensing is as follows this pattern:

- applications and binaries are GPLv3
- libraries and components are Apache 2.0 or MIT
- documentation is Apache 2.0 or CC0-1.0
