Scorex under the hood uses Akka actor references for message passing between modules meaning there's no static type checking for class properties that use ActorRef. What you can do then is, for example,
If you want to change consensus rules or whatnot, just reference different files. Alternatively, you can always do this in memory. For reference, a simple ForgingSettings might look like this:
(This is using io.circe for json parsing) You can generally just swap between different children of Settings for different consensus modules.
Scorex also has a testkit built in if you want to do discrete runs quickly between different settings. It would essentially be handled the same way as well.
Cheers!
Code:
implicit lazy val settings = new ForgingSettings {
override val settingsJSON: Map[String, circe.Json] = settingsFromFile(settingsFilename)
}
val forger: ActorRef = actorSystem.actorOf(Props(classOf[Forger], settings, nodeViewHolderRef))
override val localInterface: ActorRef = actorSystem.actorOf(Props(classOf[BifrostLocalInterface], nodeViewHolderRef, forger, settings))
override val settingsJSON: Map[String, circe.Json] = settingsFromFile(settingsFilename)
}
val forger: ActorRef = actorSystem.actorOf(Props(classOf[Forger], settings, nodeViewHolderRef))
override val localInterface: ActorRef = actorSystem.actorOf(Props(classOf[BifrostLocalInterface], nodeViewHolderRef, forger, settings))

Thanks a ton for the detailed response, it is very useful for me. Good luck for your project.
