 * Equivocation: The evidence has a conflicting block that has the same height, but a non-deterministic field is different, e.g. time.
 * Lunatic: The evidence has a conflicting block that differs in the app hash.
 * Amnesia: The evidence has a conflicting block that is the same as the original block.
