README

Our networks configuration is structured like this:

Networks

We define the following networks:

• devnet: what a developer runs locally on their machine to simulate a full end-to-end network setup.
• testnet: what Union runs on their nodes in order to test a mainnet-like environment.
• mainnet: what runs on the public Union mainnet. ("the production environment")

Genesis

genesis/ contains the genesis configurations for each network.

Services

services/ contains all of the service-generating functions. They are defined as Nix functions so that dependencies and network-specific configuration can be injected as needed for the network in which they are used. These functions are then included in arion specs.

Arion

In devnet.nix we combine Genesis configuration and service-generating functions so that they are injected in an arion spec. Arion is a Nix wrapper around docker-compose. This allows us to create reproducible networks.
