The platform is composed of multiple Rust crates. Top-level executable binary crates include:
|
||||
|
||||
* nym-mixnode - shuffles [Sphinx](https://github.com/nymtech/sphinx) packets together to provide privacy against network-level attackers.
|
||||
* 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-gateway - acts sort of like a mailbox for mixnet messages, which removes the need for direct delivery to potentially offline or firewalled devices.
|
||||
* 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").
|
||||
* nym-explorer - a (projected) block explorer and (existing) mixnet viewer.
|
||||
* nym-wallet - a desktop wallet implemented using the [Tauri](https://tauri.studio/en/docs/about/intro) framework.
|
||||
* `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.studio/en/docs/about/intro) framework.
|
||||
<!-- 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 [our docs site](https://nymtech.net/docs/binaries/pre-built-binaries.html).
|
||||
Wallet build instructions are also available on [our docs site](https://nymtech.net/docs/wallet/desktop-wallet.html).
|
||||
* Platform build instructions are available on Nym [Operators Guide documentation](https://nymtech.net/operators/binaries/building-nym.html).
|
||||
* Wallet build instructions are available on Nym [Technical docs](https://nymtech.net/docs/wallet/desktop-wallet.html).
|
||||
|
||||
### Developing
|
||||
|
||||
There's a `.env.sample-dev` file provided which you can rename to `.env` if you want convenient logging, backtrace, or other environment variables pre-set. The `.env` file is ignored so you don't need to worry about checking it in.
|
||||
There's a [`sandbox.env`](https://github.com/nymtech/nym/envs/sandbox.env) file provided which you can rename to `.env` if you want convenient testing environment. Read more about sandbox environment in our [Operators Guide page](https://nymtech.net/operators/sandbox.html).
|
||||
|
||||
For Typescript components, please see [ts-packages](./ts-packages).

### Developer chat
|
||||
|
||||
> We used to use Keybase for developer chats, but we have since migrated to Matrix and Discord. We no longer check the old **nymtech.friends** Keybase team.
|
||||
|
||||
You can chat to us in two places:
|
||||
* The #dev channel on [Matrix](https://matrix.to/#/#dev:nymtech.chat)
|

### Rewards
|
||||
### Tokenomics & Rewards
|
||||
|
||||
Node, node operator and delegator rewards are determined according to the principles laid out in the section 6 of [Nym Whitepaper](https://nymtech.net/nym-whitepaper.pdf). Below is a TLDR of the variables and formulas involved in calculating the epoch rewards. Initial reward pool is set to 250 million Nym, making the circulating supply 750 million Nym.

|
||||
|
||||
Delegate with stake `s` receives:
|
||||
|
||||
<img src="https://render.githubusercontent.com/render/math?math=max\{0, (1-PM_{i}) \cdot (s^'/\sigma_{i}) \cdot (R_{i} - PP_{i})\}#gh-light-mode-only">

|
||||
|
||||
where `s'` is stake `s` scaled over total token circulating supply.
|
||||
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.
