The network with which the scenario is run can be configured in the parameters field.

The components of this object are a subset of the ones that can be found in the global configuration file (see this section for example).

fn main() {
type sandbox_param = {
  delegate_selection: mitten_delegate_selection;
  committee: int option;
  quorum: int option;
  round_durations: (int * int) option;


The scenario parameters always override the ones in the global configuration file.
