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:

...
#[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:

docker build -t nomos .
docker run nomos /etc/nomos/config.yml

To run a node with a different configuration run:

docker run -v /path/to/config.yml:/etc/nomos/config.yml nomos /etc/nomos/config.yml
