Complier Service package

Model: QmW3dTa1QZxnZzpF9TDuHKN7GDKaJDVoQys4u38xmdAGHF

The service offsets CO2 footprint by burning VCU tokens

1 MWh of non-renewable electricity produces 1 ton of C02. 1 t of C02 is covered by consuption of 1 VCU.

The payment token is DAI. 1 DAI token is $1

Scenerio

1. A user sends a demand message with the amount of electricity written in objective and the name of the country. The cost is 0
2. The service calculates the price and sends an offer back
3. If the user agree, a new offer with the price is sent
4. After a liability is created, the service converts the electricity to the amount of VCU tokens and burns it

Objecitve topics

• /geo - the name of the country
• /power_kwh - the amount of the electricity power in kHw

Build

nix build -f release.nix

Launch

By default the agent is set up to work in (sidechain)[https://github.com/airalab/airalab-sidechain] network. To run in a different network change the following properties in the agent.launch file

<param name="model" value="QmW3dTa1QZxnZzpF9TDuHKN7GDKaJDVoQys4u38xmdAGHF" />
<param name="token" value="0x7cfd3337F9e423751C9314f9C80cbA57CA2844FE" />

To launch manually run:

source result/setup.zsh (bash)
roslaunch complier_service agent.launch

or as a NixOS service add the following lines to /etc/nixos/configuration.nix:

systemd.services.complier_service = {
      requires = [ "roscore.service" ];
      after = ["roscore.service" ];
      wantedBy = [ "multi-user.target" ];
      script = ''
        source /root/complier_service/result/setup.bash \
        && roslaunch complier_service agent.launch
      '';
      serviceConfig = {
        Restart = "on-failure";
        StartLimitInterval = 0;
        RestartSec = 60;
        User = "root";
      };
    };
