Nomos blockchain node mvp
|
|
|
|
|
|
## Project structure
|
|
|
|
- `nomos-core`: Nomos core is the collection of essential structures for the Nomos mvp and experimental nodes.
|
|
- `nomos-services`: Nomos services is the collection of components that are used as building blocks of the Nomos node prototype and the experimental nodes.
|
|
- consensus
|
|
- log
|
|
- http
|
|
- mempool
|
|
- network
|
|
- metrics
|
|
- `nodes`: Nomos nodes is the collection of nodes that are used to run the Nomos mvp and experimental nodes.
|
|
- `nomos-node`: main implementation of the Nomos mvp node.
|
|
- `mockpool-node`: node with single mempool service, used to measure transaction dissemination.
|
|
|
|
|
|
## Services
|
|
|
|
The Nomos node uses `Overwatch` as its main internal framework. This means that services request communication channels
|
|
to other services to interchange information through a specified messaging API.
|
|
|
|
### Service architecture
|
|
|
|
Most of the services are implemented with the same idea behind. There is a front layer responsible for handling the `Overwatch` service
|
|
and a back layer that implement the actual service logic.
|
|
|
|
This allows us to easily replace components as needed in a type level system. In any case, a node can be setup in a declarative way composing the types.
|
|
For example:
|
|
|
|
```rust
|
|
...
|
|
#[derive(Services)]
|
|
struct MockPoolNode {
|
|
logging: ServiceHandle<Logger>,
|
|
network: ServiceHandle<NetworkService<Waku>>,
|
|
mockpool: ServiceHandle<MempoolService<WakuAdapter<Tx>, MockPool<TxId, Tx>>>,
|
|
http: ServiceHandle<HttpService<AxumBackend>>,
|
|
bridges: ServiceHandle<HttpBridgeService>,
|
|
}
|
|
```
|
|
|
|
|
|
|
|
## Docker
|
|
|
|
To build and run a docker container with Nomos node run:
|
|
|
|
```bash
|
|
docker build -t nomos .
|
|
docker run nomos /etc/nomos/config.yml
|
|
```
|
|
|
|
To run a node with a different configuration run:
|
|
|
|
```bash
|
|
docker run -v /path/to/config.yml:/etc/nomos/config.yml nomos /etc/nomos/config.yml
|
|
```
