+The proposal details must be supplied via a JSON file. For values that contains

+
+IMPORTANT: Currently parameter changes are evaluated but not validated, so it is
+very important that any "value" change is valid (ie. correct type and within bounds)
+for its respective parameter, eg. "MaxValidators" should be an integer and not a decimal.
+
+Proper vetting of a parameter change proposal should prevent this from happening
+(no deposits should occur during the governance process), but it should be noted
+regardless.
