However, apparently its usage is fine... Having said that, I'd still recommend removing all dependencies on chrono, but this will require some database migrations... * 2023-01-13-OAK-11 (#3009) * wip * Introducing the concept of starting epoch transition in `nym-api` * split epoch operations into multiple files * epoch operation failure recovery * sending rewarding transactions in correct order * tests and fixes due to epoch state progression * lint * missed rebasing import changes * Setting cw2 contract version during first migration run * calling 'reconcile_epoch_events' at least once * Made message to BeginEpochTransition more consistent with other variants * Merge layer assignment updates --------- Co-authored-by: Jędrzej Stuczyński <jedrzej.stuczynski@gmail.com>
The Nym Privacy Platform
The platform is composed of multiple Rust crates. Top-level executable binary crates include:
- nym-mixnode - shuffles 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 framework.
Building
Platform build instructions are available on our docs site. Wallet build instructions are also available on our docs site.
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.
For Typescript components, please see ts-packages.
Developer chat
You can chat to us in Keybase. Download their chat app, then click Teams -> Join a team. Type nymtech.friends into the team name and hit continue. For general chat, hang out in the #general channel. Our development takes places in the #dev channel. Node operators should be in the #node-operators channel.
Rewards
Node, node operator and delegator rewards are determined according to the principles laid out in the section 6 of Nym Whitepaper. 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.
| Symbol | Definition |
|---|---|
| global share of rewards available, starts at 2% of the reward pool. | |
node reward for mixnode i. |
|
| ratio of total node stake (node bond + all delegations) to the token circulating supply. | |
| ratio of stake operator has pledged to their node to the token circulating supply. | |
fraction of total effort undertaken by node i, set to 1/k. |
|
number of nodes stakeholders are incentivised to create, set by the validators, a matter of governance. Currently determined by the reward set size, and set to 720 in testnet Sandbox. |
|
| Sybil attack resistance parameter - the higher this parameter is set the stronger the reduction in competitivness gets for a Sybil attacker. | |
declared profit margin of operator i, defaults to 10% in. |
|
uptime of node i, scaled to 0 - 1, for the rewarding epoch |
|
cost of operating node i for the duration of the rewarding epoch, set to 40 NYMT. |
Node reward for node i is determined as:
and
Operator of node i is credited with the following amount:
Delegate with stake s recieves:
where s' is stake s scaled over total token circulating supply.
